Python 3.10+, packaged with hatchling, managed with uv.\n\n## Setup\n\n```bash\nuv venv --python 3.12\nuv pip install -e \".[dev]\"\n```\n\n## Before Committing\n\nAll of these must pass — CI enforces them:\n\n```bash\nruff check src/               # Lint (E, F, I, W, B rules)\nruff format --check src/      # Format check\nmypy src/mcp_server_tree_sitter  # Type check\npytest tests/                  # 217+ tests, must all pass\n```\n\nOr use the Makefile: `make prepare`\n\n## Key Architecture\n\n- **Source:** `src/mcp_server_tree_sitter/`\n- **DI container:** `di.py` — constructs all dependencies; avoid circular imports with it\n- **Config:** `config.py` — `ConfigurationManager` auto-loads YAML from `MCP_TS_CONFIG_PATH` or `~/.config/tree-sitter/config.yaml`. Precedence: env vars > YAML > defaults\n- **Language registry:** `language/registry.py` — maps file extensions to tree-sitter-language-pack identifiers\n- **Templates:** `language/templates/` — per-language query templates (one file per language)\n- **Tools:** `tools/` — MCP tool implementations (analysis, search, ast_operations, file_operations)\n- **Helpers:** `utils/tree_sitter_helpers.py` — includes `query_captures()` compat wrapper for tree-sitter >= 0.24\n\n## tree-sitter API Compatibility\n\ntree-sitter >= 0.24 removed `Query.captures()`. Always use the `query_captures(query, node)` wrapper from `utils/tree_sitter_helpers.py` instead of calling `query.captures()` directly. This applies to both source and test code.\n\n## Adding a New Language\n\n1. Create `language/templates/<lang>.py` with a `TEMPLATES` dict (follow existing patterns like `go.py`)\n2. Register the file extension in `language/registry.py` `_language_map`\n3. Import and register in `language/templates/__init__.py`\n4. Add default symbol types in `tools/analysis.py` `extract_symbols()`\n5. Verify the language identifier works: `from tree_sitter_language_pack import get_language; get_language(\"<id>\")`\n\n## Common Pitfalls\n\n- **Circular imports with `di.py`:** The DI container constructs registries. Don't import `get_container` from `__init__` methods of objects the container creates. Use method injection instead.\n- **Root logger:** Do NOT call `configure_root_logger()` at module import time. Libraries must not reconfigure the root logger.\n- **`common_languages` list:** Uses tree-sitter-language-pack identifiers (e.g., `csharp` not `c_sharp`). Verify with `get_language()` before adding.\n- **TypeScript grammar:** Import statements require the `import_clause` node between `import_statement` and `named_imports`/`namespace_import`.\n- **Test isolation:** Some tests are order-dependent due to shared singleton state. If a test passes alone but fails in suite, check for state leakage.\n\n## PR Process\n\n- All PRs must pass CI (ruff check, ruff format, mypy, pytest)\n- Squash merge to main\n- Credit community contributors in commit messages and PR descriptions\n- For dependency bumps, pin transitive deps with security floors in `pyproject.toml`\n\n## Release Process\n\n1. Bump version in `pyproject.toml`\n2. Update README if features/languages changed\n3. Merge to main, confirm CI green\n4. Create GitHub release with tag `vX.Y.Z` — this triggers the release workflow which publishes to PyPI\n"

    "content": "# Contributing to MCP Tree-sitter Server\n\nThank you for your interest in contributing to MCP Tree-sitter Server! This guide will help you understand our development process and coding standards.\n\n## Development Setup\n\n1. Clone the repository:\n   ```bash\n   git clone https://github.com/organization/mcp-server-tree-sitter.git\n   cd mcp-server-tree-sitter\n   ```\n\n2. Install with development dependencies:\n   ```bash\n   make install-dev\n   ```\n\n3. Install language parsers (optional):\n   ```bash\n   make install-languages\n   ```\n\n## Code Style and Standards\n\nWe follow a strict set of coding standards to maintain consistency throughout the codebase:\n\n### Python Style\n\n- We use [Black](https://black.readthedocs.io/) for code formatting with a line length of 88 characters\n- We use [Ruff](https://github.com/charliermarsh/ruff) for linting\n- We use [MyPy](https://mypy.readthedocs.io/) for static type checking\n\n### Exception Handling\n\n- Use specific exception types rather than catching generic exceptions when possible\n- When re-raising exceptions, use the `from` clause to preserve the stack trace:\n  ```python\n  try:\n      # Some code\n  except SomeError as e:\n      raise CustomError(\"Meaningful message\") from e\n  ```\n\n### Testing\n\n- Write tests for all new functionality\n- Run tests before submitting:\n  ```bash\n  make test\n  ```\n\n### Documentation\n\n- Document all functions, classes, and modules using docstrings\n- Follow the Google Python Style Guide for docstrings\n- Include type hints for all function parameters and return values\n\n## Development Workflow\n\n1. Create a branch for your feature or bugfix:\n   ```bash\n   git checkout -b feature/your-feature-name\n   ```\n\n2. Make your changes and ensure they pass linting and tests:\n   ```bash\n   make format\n   make lint\n   make test\n   ```\n\n3. Commit your changes with a clear message describing the change\n\n4. Submit a pull request to the main repository\n\n## Running the Server\n\nYou can run the server in different modes:\n\n- For development and testing:\n  ```bash\n  make mcp-dev\n  ```\n\n- For direct execution:\n  ```bash\n  make mcp-run\n  ```\n\n- To install in Claude Desktop:\n  ```bash\n  make mcp-install\n  ```\n\n## Project Architecture\n\nThe project follows a modular architecture:\n\n- `config.py` - Configuration management\n- `language/` - Tree-sitter language handling\n- `models/` - Data models for AST and projects\n- `cache/` - Caching mechanisms\n- `resources/` - MCP resources (files, AST)\n- `tools/` - MCP tools (search, analysis, etc.)\n- `utils/` - Utility functions\n- `prompts/` - MCP prompts\n- `server.py` - FastMCP server implementation\n\n## Seeking Help\n\nIf you have questions or need help, please open an issue or contact the maintainers.\n"

All 31 languages are available and functional.\n\n| Feature Area | Status | Test Results |\n|--------------|--------|--------------|\n| Language Tools | ✅ Working | All tests pass. Language tools properly report and list available languages |\n| AST Analysis | ✅ Working | All tests pass. `get_ast` and `get_node_at_position` work correctly with proper node IDs and AST traversal operations |\n| Search Queries | ✅ Working | All tests pass. Text search works, query building works, and tree-sitter query execution returns expected results |\n| Code Analysis | ✅ Working | All tests pass. Structure and complexity analysis works, symbol extraction and dependency analysis provide useful results |\n\n**Current Integration Capabilities:**\n- AST functionality works well for retrieving and traversing trees and nodes\n- Query execution and result handling work correctly\n- Symbol extraction and dependency analysis provide useful results\n- Project management, file operations, and search features work correctly\n\n### Implementation Gaps\n\nBased on the latest tests as of March 18, 2025, these are the current implementation gaps:\n\n#### Tree Editing and Incremental Parsing\n- **Status:** ⚠️ Partially Working\n- Core AST functionality works\n- Tree manipulation functionality requires additional implementation\n\n#### Tree Cursor API\n- **Status:** ✅ Fully Working\n- AST node traversal works correctly\n- Cursor-based tree walking is efficient and reliable\n- Can be extended for more advanced semantic analysis\n\n#### Similar Code Detection\n- **Status:** ⚠️ Partially Working\n- Command executes successfully but testing did not yield results\n- May require more specific snippets or fine-tuning of similarity thresholds\n\n#### UTF-16 Support\n- **Status:** ❌ Not Implemented\n- Encoding detection and support is not yet available\n- Will require parser improvements after core AST functionality is fixed\n\n#### Read Callable Support\n- **Status:** ❌ Not Implemented\n- Custom read strategies are not yet available\n- Streaming parsing for large files remains unavailable\n\n### MCP SDK Implementation\n\n| Feature | Status | Notes |\n|---------|--------|-------|\n| Application Lifecycle Management | ✅ Working | Basic lifespan support is functioning correctly |\n| Image Handling | ❌ Not Implemented | No support for returning images from tools |\n| MCP Context Handling | ⚠️ Partial | Basic context access works, but progress reporting not fully implemented |\n| Claude Desktop Integration | ✅ Working | MCP server can be installed in Claude Desktop |\n| Server Capabilities Declaration | ✅ Working | Capabilities are properly declared |\n\n---\n\n## Implementation Notes\n\nThis project uses a structured dependency injection (DI) pattern, but still has global singletons at its core:\n\n1. A central `DependencyContainer` singleton that holds all shared services\n2. A `global_context` object that provides a convenient interface to the container\n3. API functions that access the container internally\n\nThis architecture provides three main ways to access functionality:\n\n```python\n# Option 1: API Functions (preferred for most use cases)\nfrom mcp_server_tree_sitter.api import get_config, get_language_registry\n\nconfig = get_config()\nlanguages = get_language_registry().list_available_languages()\n\n# Option 2: Direct Container Access\nfrom mcp_server_tree_sitter.di import get_container\n\ncontainer = get_container()\nproject_registry = container.project_registry\ntree_cache = container.tree_cache\n\n# Option 3: Global Context\nfrom mcp_server_tree_sitter.context import global_context\n\nconfig = global_context.get_config()\nresult = global_context.register_project(\"/path/to/project\")\n```\n\nThe dependency injection approach helps make the code more testable and maintainable, even though it still uses singletons internally.\n\n---\n\n## Testing Guidelines\n\nWhen testing the MCP Tree-sitter server, use this structured approach:\n\n1. **Project Setup**\n   - Register a project with `register_project_tool`\n   - Verify registration with `list_projects_tool`\n\n2. **Basic File Operations**\n   - Test `list_files` to ensure project access\n   - Test `get_file` to verify content retrieval\n   - Test `get_file_metadata` to check file information\n\n3. **Language Parser Verification**\n   - Test `check_language_available` to verify specific language support\n   - Use `list_languages` to see all available languages\n\n4. **Feature Testing**\n   - Test AST operations with `get_ast` to ensure proper node IDs and structure\n   - Test query execution with `run_query` to verify proper result capture\n   - Test symbol extraction with `get_symbols` to verify proper function, class, and import detection\n   - Test dependency analysis with `get_dependencies` to verify proper import detection\n   - Test complexity analysis with `analyze_complexity` to verify metrics are being calculated correctly\n   - Test usage finding with `find_usage` to verify proper symbol reference detection\n\n5. **Test Outcomes**\n   - All 185 tests now pass successfully\n   - No diagnostic errors reported\n   - Core functionality works reliably across all test cases\n\n---\n\n## Implementation Progress\n\nBased on the test results as of March 18, 2025, all critical functionality is now working:\n\n1. **✅ Tree-Sitter Query Result Handling**\n   - Query result handling works correctly\n   - Queries execute and return proper results with correct capture processing\n\n2. **✅ Tree Cursor Functionality**\n   - Tree cursor-based traversal is working correctly\n   - Efficient navigation and analysis of ASTs is now possible\n\n3. **✅ AST Node ID Generation**\n   - AST nodes are correctly assigned unique IDs\n   - Node traversal and reference works reliably\n\n4. **✅ Symbol Extraction**\n   - Symbol extraction correctly identifies functions, classes, and imports\n   - Location information is accurate\n\n5. **✅ Dependency Analysis**\n   - Dependency analysis correctly identifies imports and references\n   - Properly handles different import styles\n\n6. **✅ Code Complexity Analysis**\n   - Complexity metrics are calculated correctly\n   - Line counts, cyclomatic complexity, and other metrics are accurate\n\n7. **⚠️ Similar Code Detection**\n   - Command completes execution but testing did not yield results\n   - May need further investigation with more appropriate test cases\n\n8. **Future Work: Complete MCP Context Progress Reporting**\n   - Add progress reporting for long-running operations to improve user experience\n\n---\n\nThis feature matrix reflects test results as of March 18, 2025. All core functionality is now working correctly, with only minor issues in similar code detection. The project is fully operational with all 185 tests passing successfully.\n"

    "content": "# MCP Tree-sitter Server\n\nA Model Context Protocol (MCP) server that provides code analysis capabilities using tree-sitter, designed to give AI assistants intelligent access to codebases with appropriate context management. Claude Desktop is the reference implementation target.\n\n## Features\n\n- 🔍 **Flexible Exploration**: Examine code at multiple levels of granularity\n- 🧠 **Context Management**: Provides just enough information without overwhelming the context window\n- 🌐 **Language Agnostic**: Supports many programming languages including Python, JavaScript, TypeScript, Go, Rust, C, C++, C#, Swift, Java, Kotlin, Dart, Julia, and APL via tree-sitter-language-pack\n- 🌳 **Structure-Aware**: Uses AST-based understanding with efficient cursor-based traversal\n- 🔎 **Searchable**: Find specific patterns using text search and tree-sitter queries\n- 🔄 **Caching**: Optimized performance through parse tree caching\n- 🔑 **Symbol Extraction**: Extract and analyze functions, classes, and other code symbols\n- 📊 **Dependency Analysis**: Identify and analyze code dependencies and relationships\n- 🧩 **State Persistence**: Maintains project registrations and cached data between invocations\n- 🔒 **Secure**: Built-in security boundaries and input validation\n\nFor a comprehensive list of all available commands, their current implementation status, and detailed feature matrix, please refer to the [FEATURES.md](FEATURES.md) document.\n\n## Installation\n\n### Prerequisites\n\n- Python 3.10+\n- Tree-sitter language parsers for your preferred languages\n\n### Basic Installation\n\n```bash\npip install mcp-server-tree-sitter\n```\n\n### Development Installation\n\n```bash\ngit clone https://github.com/wrale/mcp-server-tree-sitter.git\ncd mcp-server-tree-sitter\npip install -e \".[dev]\"\n```\n\n## Quick Start\n\n### Running with Claude Desktop\n\nYou can make the server available in Claude Desktop either through the MCP CLI or by manually configuring Claude Desktop.\n\n#### Using MCP CLI\n\nRegister the server with Claude Desktop:\n\n```bash\nmcp install mcp_server_tree_sitter.server:mcp --name \"tree_sitter\"\n```\n\n#### Manual Configuration\n\nAlternatively, you can manually configure Claude Desktop:\n\n1. Open your Claude Desktop configuration file:\n   - macOS/Linux: `~/Library/Application Support/Claude/claude_desktop_config.json`\n   - Windows: `%APPDATA%\\Claude\\claude_desktop_config.json`\n   \n   Create the file if it doesn't exist.\n\n2. Add the server to the `mcpServers` section:\n\n   ```json\n   {\n       \"mcpServers\": {\n           \"tree_sitter\": {\n               \"command\": \"python\",\n               \"args\": [\n                   \"-m\",\n                   \"mcp_server_tree_sitter.server\"\n               ]\n           }\n       }\n   }\n   ```\n\n   Alternatively, if using uv or another package manager:\n\n   ```json\n   {\n       \"mcpServers\": {\n           \"tree_sitter\": {\n               \"command\": \"uv\",\n               \"args\": [\n                   \"--directory\",\n                   \"/ABSOLUTE/PATH/TO/YOUR/PROJECT\",\n                   \"run\",\n                   \"-m\",\n                   \"mcp_server_tree_sitter.server\"\n               ]\n           }\n       }\n   }\n   ```\n\n   Note: Make sure to replace `/ABSOLUTE/PATH/TO/YOUR/PROJECT` with the actual absolute path to your project directory.\n\n3. Save the file and restart Claude Desktop.\n\nThe MCP tools icon (hammer) will appear in Claude Desktop's interface once you have properly configured at least one MCP server. You can then access the `tree_sitter` server's functionality by clicking on this icon.\n\n### Configuring with Released Version\n\nIf you prefer not to manually install the package from PyPI (released version) or clone the repository, simply use the following configuration for Claude Desktop:\n\n1. Open your Claude Desktop configuration file (same location as above).\n\n2. Add the tree-sitter server to the `mcpServers` section:\n\n   ```json\n   {\n       \"mcpServers\": {\n           \"tree_sitter\": {\n               \"command\": \"uvx\",\n               \"args\": [\n                   \"--directory\", \"/ABSOLUTE/PATH/TO/YOUR/PROJECT\",\n                   \"mcp-server-tree-sitter\"\n               ]\n           }\n       }\n   }\n   ```\n\n3. Save the file and restart Claude Desktop.\n\nThis method uses `uvx` to run the installed PyPI package directly, which is the recommended approach for the released version. The server doesn't require any additional parameters to run in its basic configuration.\n\n## State Persistence\n\nThe MCP Tree-sitter Server maintains state between invocations. This means:\n- Projects stay registered until explicitly removed or the server is restarted\n- Parse trees are cached according to configuration settings\n- Language information is retained throughout the server's lifetime\n\nThis persistence is maintained in-memory during the server's lifetime using singleton patterns for key components.\n\n### Running as a standalone server\n\nThere are several ways to run the server:\n\n#### Using the MCP CLI directly:\n\n```bash\npython -m mcp run mcp_server_tree_sitter.server\n```\n\n#### Using Makefile targets:\n\n```bash\n# Show available targets\nmake\n\n# Run the server with default settings\nmake mcp-run\n\n# Show help information\nmake mcp-run ARGS=\"--help\"\n\n# Show version information\nmake mcp-run ARGS=\"--version\"\n\n# Run with custom configuration file\nmake mcp-run ARGS=\"--config /path/to/config.yaml\"\n\n# Enable debug logging\nmake mcp-run ARGS=\"--debug\"\n\n# Disable parse tree caching\nmake mcp-run ARGS=\"--disable-cache\"\n```\n\n#### Using the installed script:\n\n```bash\n# Run the server with default settings\nmcp-server-tree-sitter\n\n# Show help information\nmcp-server-tree-sitter --help\n\n# Show version information\nmcp-server-tree-sitter --version\n\n# Run with custom configuration file\nmcp-server-tree-sitter --config /path/to/config.yaml\n\n# Enable debug logging\nmcp-server-tree-sitter --debug\n\n# Disable parse tree caching\nmcp-server-tree-sitter --disable-cache\n```\n\n### Using with the MCP Inspector\n\nUsing the MCP CLI directly:\n\n```bash\npython -m mcp dev mcp_server_tree_sitter.server\n```\n\nOr using the Makefile target:\n\n```bash\nmake mcp-dev\n```\n\nYou can also pass arguments:\n\n```bash\nmake mcp-dev ARGS=\"--debug\"\n```\n\n## Usage\n\n### Register a Project\n\nFirst, register a project to analyze:\n\n```\nregister_project_tool(path=\"/path/to/your/project\", name=\"my-project\")\n```\n\n### Explore Files\n\nList files in the project:\n\n```\nlist_files(project=\"my-project\", pattern=\"**/*.py\")\n```\n\nView file content:\n\n```\nget_file(project=\"my-project\", path=\"src/main.py\")\n```\n\n### Analyze Code Structure\n\nGet the syntax tree:\n\n```\nget_ast(project=\"my-project\", path=\"src/main.py\", max_depth=3)\n```\n\nExtract symbols:\n\n```\nget_symbols(project=\"my-project\", path=\"src/main.py\")\n```\n\n### Search Code\n\nSearch for text:\n\n```\nfind_text(project=\"my-project\", pattern=\"function\", file_pattern=\"**/*.py\")\n```\n\nRun tree-sitter queries:\n\n```\nrun_query(\n    project=\"my-project\",\n    query='(function_definition name: (identifier) @function.name)',\n    language=\"python\"\n)\n```\n\n### Analyze Complexity\n\n```\nanalyze_complexity(project=\"my-project\", path=\"src/main.py\")\n```\n\n## Direct Python Usage\n\nWhile the primary intended use is through the MCP server, you can also use the library directly in Python code:\n\n```python\n# Import from the API module\nfrom mcp_server_tree_sitter.api import (\n    register_project, list_projects, get_config, get_language_registry\n)\n\n# Register a project\nproject_info = register_project(\n    path=\"/path/to/project\", \n    name=\"my-project\", \n    description=\"Description\"\n)\n\n# List projects\nprojects = list_projects()\n\n# Get configuration\nconfig = get_config()\n\n# Access components through dependency injection\nfrom mcp_server_tree_sitter.di import get_container\ncontainer = get_container()\nproject_registry = container.project_registry\nlanguage_registry = container.language_registry\n```\n\n## Configuration\n\nCreate a YAML configuration file:\n\n```yaml\ncache:\n  enabled: true                # Enable/disable caching (default: true)\n  max_size_mb: 100             # Maximum cache size in MB (default: 100)\n  ttl_seconds: 300             # Cache entry time-to-live in seconds (default: 300)\n\nsecurity:\n  max_file_size_mb: 5          # Maximum file size to process in MB (default: 5)\n  excluded_dirs:               # Directories to exclude from processing\n    - .git\n    - node_modules\n    - __pycache__\n  allowed_extensions:          # Optional list of allowed file extensions\n    # - py\n    # - js\n    # Leave empty or omit for all extensions\n\nlanguage:\n  default_max_depth: 5         # Default max depth for AST traversal (default: 5)\n  preferred_languages:         # List of languages to pre-load at startup for faster performance\n    - python                   # Pre-loading reduces latency for first operations\n    - javascript\n\nlog_level: INFO                # Logging level (DEBUG, INFO, WARNING, ERROR)\nmax_results_default: 100       # Default maximum results for search operations\n```\n\nLoad it with:\n\n```\nconfigure(config_path=\"/path/to/config.yaml\")\n```\n\n### Logging Configuration\n\nThe server's logging verbosity can be controlled using environment variables:\n\n```bash\n# Enable detailed debug logging\nexport MCP_TS_LOG_LEVEL=DEBUG\n\n# Use normal informational logging (default)\nexport MCP_TS_LOG_LEVEL=INFO\n\n# Only show warning and error messages\nexport MCP_TS_LOG_LEVEL=WARNING\n```\n\nFor comprehensive information about logging configuration, please refer to the [logging documentation](docs/logging.md). For details on the command-line interface, see the [CLI documentation](docs/cli.md).\n\n### About preferred_languages\n\nThe `preferred_languages` setting controls which language parsers are pre-loaded at server startup rather than on-demand. This provides several benefits:\n\n- **Faster initial analysis**: No delay when first analyzing a file of a pre-loaded language\n- **Early error detection**: Issues with parsers are discovered at startup, not during use\n- **Predictable memory allocation**: Memory for frequently used parsers is allocated upfront\n\nBy default, all parsers are loaded on-demand when first needed. For optimal performance, specify the languages you use most frequently in your projects.\n\nYou can also configure specific settings:\n\n```\nconfigure(cache_enabled=True, max_file_size_mb=10, log_level=\"DEBUG\")\n```\n\nOr use environment variables:\n\n```bash\nexport MCP_TS_CACHE_MAX_SIZE_MB=256\nexport MCP_TS_LOG_LEVEL=DEBUG\nexport MCP_TS_CONFIG_PATH=/path/to/config.yaml\n```\n\nEnvironment variables use the format `MCP_TS_SECTION_SETTING` (e.g., `MCP_TS_CACHE_MAX_SIZE_MB`) for section settings, or `MCP_TS_SETTING` (e.g., `MCP_TS_LOG_LEVEL`) for top-level settings.\n\nConfiguration values are applied in this order of precedence:\n1. Environment variables (highest)\n2. Values set via `configure()` calls\n3. YAML configuration file\n4. Default values (lowest)\n\nThe server will look for configuration in:\n1. Path specified in `configure()` call\n2. Path specified by `MCP_TS_CONFIG_PATH` environment variable\n3. Default location: `~/.config/tree-sitter/config.yaml`\n\n## For Developers\n\n### Diagnostic Capabilities\n\nThe MCP Tree-sitter Server includes a diagnostic framework to help identify and fix issues:\n\n```bash\n# Run diagnostic tests\nmake test-diagnostics\n\n# CI-friendly version (won't fail the build on diagnostic issues)\nmake test-diagnostics-ci\n```\n\nDiagnostic tests provide detailed information about the server's behavior and can help isolate specific issues. For more information about the diagnostic framework, please see the [diagnostics documentation](docs/diagnostics.md).\n\n### Type Safety Considerations\n\nThe MCP Tree-sitter Server maintains type safety when interfacing with tree-sitter libraries through careful design patterns and protocols. If you're extending the codebase, please review the [type safety guide](docs/tree-sitter-type-safety.md) for important information about handling tree-sitter API variations.\n\n## Available Resources\n\nThe server provides the following MCP resources:\n\n- `project://{project}/files` - List all files in a project\n- `project://{project}/files/{pattern}` - List files matching a pattern\n- `project://{project}/file/{path}` - Get file content\n- `project://{project}/file/{path}/lines/{start}-{end}` - Get specific lines from a file\n- `project://{project}/ast/{path}` - Get the AST for a file\n- `project://{project}/ast/{path}/depth/{depth}` - Get the AST with custom depth\n\n## Available Tools\n\nThe server provides tools for:\n\n- Project management: `register_project_tool`, `list_projects_tool`, `remove_project_tool`\n- Language management: `list_languages`, `check_language_available`\n- File operations: `list_files`, `get_file`, `get_file_metadata`\n- AST analysis: `get_ast`, `get_node_at_position`\n- Code search: `find_text`, `run_query`\n- Symbol extraction: `get_symbols`, `find_usage`\n- Project analysis: `analyze_project`, `get_dependencies`, `analyze_complexity`\n- Query building: `get_query_template_tool`, `list_query_templates_tool`, `build_query`, `adapt_query`, `get_node_types`\n- Similar code detection: `find_similar_code`\n- Cache management: `clear_cache`\n- Configuration diagnostics: `diagnose_config`\n\nSee [FEATURES.md](FEATURES.md) for detailed information about each tool's implementation status, dependencies, and usage examples.\n\n## Available Prompts\n\nThe server provides the following MCP prompts:\n\n- `code_review` - Create a prompt for reviewing code\n- `explain_code` - Create a prompt for explaining code\n- `explain_tree_sitter_query` - Explain tree-sitter query syntax\n- `suggest_improvements` - Create a prompt for suggesting code improvements\n- `project_overview` - Create a prompt for a project overview analysis\n\n## Feedback & Community\n\nWe'd love to hear how you're using mcp-server-tree-sitter and what would make it more useful for your workflow.\n\n- **Questions & Feature Requests**: [GitHub Discussions](https://github.com/wrale/mcp-server-tree-sitter/discussions)\n- **Bug Reports**: [GitHub Issues](https://github.com/wrale/mcp-server-tree-sitter/issues)\n\n## License\n\nMIT"

    "content": "# Architecture Overview\n\nThis document provides an overview of the MCP Tree-sitter Server's architecture, focusing on key components and design patterns.\n\n## Core Architecture\n\nThe MCP Tree-sitter Server follows a structured architecture with the following components:\n\n1. **Bootstrap Layer**: Core initialization systems that must be available to all modules with minimal dependencies\n2. **Configuration Layer**: Configuration management with environment variable support\n3. **Dependency Injection Container**: Central container for managing and accessing services\n4. **Tree-sitter Integration**: Interfaces with the tree-sitter library for parsing and analysis\n5. **MCP Protocol Layer**: Handles interactions with the Model Context Protocol\n\n## Bootstrap Layer\n\nThe bootstrap layer handles critical initialization tasks that must happen before anything else:\n\n```\nsrc/mcp_server_tree_sitter/bootstrap/\n├── __init__.py           # Exports key bootstrap functions\n└── logging_bootstrap.py  # Canonical logging configuration\n```\n\nThis layer is imported first in the package's `__init__.py` and has minimal dependencies. The bootstrap module ensures that core services like logging are properly initialized and globally available to all modules.\n\n**Key Design Principle**: Each component in the bootstrap layer must have minimal dependencies to avoid import cycles and ensure reliable initialization.\n\n## Dependency Injection Pattern\n\nInstead of using global variables (which was the approach in earlier versions), the application now uses a structured dependency injection pattern:\n\n1. **DependencyContainer**: The `DependencyContainer` class holds all application components and services\n2. **ServerContext**: A context class provides a clean interface for interacting with dependencies\n3. **Access Functions**: API functions like `get_logger()` and `update_log_levels()` provide easy access to functionality\n\nThis approach has several benefits:\n- Cleaner testing with the ability to mock dependencies\n- Better encapsulation of implementation details\n- Reduced global state and improved thread safety\n- Clearer dependency relationships between components\n\n## Logging Design\n\nLogging follows a hierarchical model using Python's standard `logging` module:\n\n1. **Root Package Logger**: Only the root package logger (`mcp_server_tree_sitter`) has its level explicitly set\n2. **Child Loggers**: Child loggers inherit their level from the root package logger\n3. **Handler Synchronization**: Handler levels are synchronized with their logger's effective level\n\n**Canonical Implementation**: The logging system is defined in a single location - `bootstrap/logging_bootstrap.py`. Other modules import from this module to ensure consistent behavior.\n\n### Logging Functions\n\nThe bootstrap module provides these key logging functions:\n\n```python\n# Get log level from environment variable\nget_log_level_from_env()\n\n# Configure the root logger\nconfigure_root_logger()\n\n# Get a properly configured logger\nget_logger(name)\n\n# Update log levels\nupdate_log_levels(level_name)\n```\n\n## Configuration System\n\nThe configuration system uses a layered approach:\n\n1. **Environment Variables**: Highest precedence (e.g., `MCP_TS_LOG_LEVEL=DEBUG`)\n2. **Explicit Updates**: Updates made via `update_value()` calls\n3. **YAML Configuration**: Settings from YAML configuration files\n4. **Default Values**: Fallback defaults defined in model classes\n\nThe `ConfigurationManager` is responsible for loading, managing, and applying configuration, while a `ServerConfig` model encapsulates the actual configuration settings.\n\n## Project and Language Management\n\nProjects and languages are managed by registry classes:\n\n1. **ProjectRegistry**: Maintains active project registrations\n2. **LanguageRegistry**: Manages tree-sitter language parsers\n\nThese registries are accessed through the dependency container or context, providing a clean interface for operations.\n\n## Use of Builder and Factory Patterns\n\nThe server uses several design patterns for cleaner code:\n\n1. **Builder Pattern**: Used for constructing complex objects like `Project` instances\n2. **Factory Methods**: Used to create tree-sitter parsers and queries\n3. **Singleton Pattern**: Used for the dependency container to ensure consistent state\n\n## Lifecycle Management\n\nThe server's lifecycle is managed in a structured way:\n\n1. **Bootstrap Phase**: Initializes logging and critical systems (from `__init__.py`)\n2. **Configuration Phase**: Loads configuration from files and environment\n3. **Dependency Initialization**: Sets up all dependencies in the container\n4. **Server Setup**: Configures MCP tools and capabilities\n5. **Running Phase**: Processes requests from the MCP client\n6. **Shutdown**: Gracefully handles shutdown and cleanup\n\n## Error Handling Strategy\n\nThe server implements a layered error handling approach:\n\n1. **Custom Exceptions**: Defined in `exceptions.py` for specific error cases\n2. **Function-Level Handlers**: Most low-level functions do error handling\n3. **Tool-Level Handlers**: MCP tools handle errors and return structured responses\n4. **Global Exception Handling**: FastMCP provides top-level error handling\n\n## Future Architecture Improvements\n\nPlanned architectural improvements include:\n\n1. **Complete Decoupling**: Further reduce dependencies between components\n2. **Module Structure Refinement**: Better organize modules by responsibility\n3. **Configuration Caching**: Optimize configuration access patterns\n4. **Async Support**: Add support for asynchronous operations\n5. **Plugin Architecture**: Support for extensibility through plugins\n"

    "content": "# MCP Tree-sitter Server Configuration Guide\n\nThis document explains the configuration system for the MCP Tree-sitter Server, including both the YAML configuration format and the internal architecture changes for configuration management.\n\n## YAML Configuration Format\n\nThe MCP Tree-sitter Server can be configured using a YAML file with the following sections:\n\n### Cache Settings\n\nControls the parser tree cache behavior:\n\n```yaml\ncache:\n  enabled: true                # Enable/disable caching (default: true)\n  max_size_mb: 100             # Maximum cache size in MB (default: 100)\n  ttl_seconds: 300             # Cache entry time-to-live in seconds (default: 300)\n```\n\n### Security Settings\n\nControls security boundaries:\n\n```yaml\nsecurity:\n  max_file_size_mb: 5          # Maximum file size to process in MB (default: 5)\n  excluded_dirs:               # Directories to exclude from processing\n    - .git\n    - node_modules\n    - __pycache__\n  allowed_extensions:          # Optional list of allowed file extensions\n    # - py\n    # - js\n    # - ts\n    # Leave empty or omit for all extensions\n```\n\n### Language Settings\n\nControls language behavior:\n\n```yaml\nlanguage:\n  auto_install: false          # DEPRECATED: No longer used with tree-sitter-language-pack\n  default_max_depth: 5         # Default max depth for AST traversal (default: 5)\n  preferred_languages:         # List of languages to pre-load at server startup for improved performance\n    - python                   # Pre-loading reduces latency for first operations\n    - javascript\n    - typescript\n```\n\n### General Settings\n\nControls general server behavior:\n\n```yaml\nlog_level: INFO               # General logging level (DEBUG, INFO, WARNING, ERROR)\nmax_results_default: 100      # Default maximum results for search operations\n```\n\n### Complete Example\n\nHere's a complete example configuration file:\n\n```yaml\ncache:\n  enabled: true\n  max_size_mb: 256\n  ttl_seconds: 3600\n\nsecurity:\n  max_file_size_mb: 10\n  excluded_dirs:\n    - .git\n    - node_modules\n    - __pycache__\n    - .cache\n    - .venv\n    - vendor\n  allowed_extensions:\n    - py\n    - js\n    - ts\n    - rs\n    - go\n\nlanguage:\n  default_max_depth: 7\n  preferred_languages:\n    - python         # Pre-load these language parsers at startup\n    - javascript      # for faster initial performance\n    - typescript\n\nlog_level: INFO\nmax_results_default: 100\n```\n\n## Deprecated Settings\n\nThe following settings are deprecated and should not be used in new configurations:\n\n```yaml\nlanguage:\n  auto_install: true  # DEPRECATED: No longer used with tree-sitter-language-pack\n```\n\nThis setting was used to control automatic installation of language parsers, but it's no longer relevant since the server now uses tree-sitter-language-pack which includes all supported languages.\n\n## Language Settings: preferred_languages\n\nThe `preferred_languages` setting allows you to specify which language parsers should be pre-loaded at server startup:\n\n```yaml\nlanguage:\n  preferred_languages:\n    - python\n    - javascript\n    - typescript\n```\n\n**Purpose and benefits:**\n\n- **Performance improvement**: Pre-loading parsers avoids the latency of loading them on first use\n- **Early error detection**: Any issues with parsers are detected at startup, not during operation\n- **Predictable memory usage**: Memory for parsers is allocated upfront\n\nBy default, this list is empty and parsers are loaded on-demand when first needed. For best performance, specify the languages you plan to use most frequently in your projects.\n\n## Configuration Architecture\n\n### Dependency Injection Approach\n\nThe MCP Tree-sitter Server uses a dependency injection (DI) pattern for configuration management. This is implemented with a central container and a global context that serve as structured access points. This approach improves:\n\n- **Testability**: Components can be tested with mock configurations\n- **Thread safety**: Configuration access is centralized with proper locking\n- **Modularity**: Components are decoupled from direct global variable access\n\nWhile the system does use singleton objects internally, they are accessed through proper dependency injection patterns rather than direct global variable usage.\n\n### Key Components\n\n#### Dependency Container\n\nThe central component is the `DependencyContainer` which holds all shared services:\n\n```python\nfrom mcp_server_tree_sitter.di import get_container\n\n# Get the global container instance\ncontainer = get_container()\n\n# Access services\nconfig_manager = container.config_manager\nproject_registry = container.project_registry\nlanguage_registry = container.language_registry\ntree_cache = container.tree_cache\n```\n\n#### ServerContext\n\nThe `ServerContext` provides a convenient high-level interface to the container:\n\n```python\nfrom mcp_server_tree_sitter.context import ServerContext, global_context\n\n# Use the global context instance\nconfig = global_context.get_config()\n\n# Or create a custom context for testing\ntest_context = ServerContext()\ntest_config = test_context.get_config()\n```\n\n#### API Functions\n\nThe most convenient way to access functionality is through API functions:\n\n```python\nfrom mcp_server_tree_sitter.api import get_config, get_language_registry, register_project\n\n# Access services through API functions\nconfig = get_config()\nlanguage_registry = get_language_registry()\nproject = register_project(\"/path/to/project\")\n```\n\n### Global Context vs. Pure Dependency Injection\n\nThe server provides multiple approaches to accessing services:\n\n1. **API Functions**: For simplicity and convenience, most code should use these functions\n2. **Dependency Container**: For more control, access the container directly\n3. **Global Context**: A higher-level interface to the container\n4. **Pure DI**: For testing, components can accept explicit dependencies as parameters\n\nExample of pure DI:\n\n```python\ndef configure_with_context(context, config_path=None, cache_enabled=None, ...):\n    # Use the provided context rather than global state\n    result, config = context.config_manager.load_from_file(config_path)\n    return result, config\n```\n\n## Configuring the Server\n\n### Using the MCP Tool\n\nUse the `configure` MCP tool to apply configuration:\n\n```python\n# Load from YAML file\nconfigure(config_path=\"/path/to/config.yaml\")\n\n# Set specific values\nconfigure(cache_enabled=True, max_file_size_mb=10, log_level=\"DEBUG\")\n```\n\n### Using Environment Variables\n\nSet environment variables to configure the server:\n\n```sh\n# Set cache size\nexport MCP_TS_CACHE_MAX_SIZE_MB=256\n\n# Set log level\nexport MCP_TS_LOG_LEVEL=DEBUG\n\n# Set config file path \nexport MCP_TS_CONFIG_PATH=/path/to/config.yaml\n\n# Run the server\nmcp run mcp_server_tree_sitter.server\n```\n\nEnvironment variables use the format `MCP_TS_SECTION_SETTING` where:\n- `MCP_TS_` is the required prefix for all environment variables\n- `SECTION` corresponds to a configuration section (e.g., `CACHE`, `SECURITY`, `LANGUAGE`)\n- `SETTING` corresponds to a specific setting within that section (e.g., `MAX_SIZE_MB`, `MAX_FILE_SIZE_MB`)\n\nFor top-level settings like `log_level`, the format is simply `MCP_TS_SETTING` (e.g., `MCP_TS_LOG_LEVEL`).\n\n#### Configuration Precedence\n\nThe server follows this precedence order when determining configuration values:\n\n1. **Environment Variables** (highest precedence)\n2. **Explicit Updates** via `update_value()`\n3. **YAML Configuration** from file\n4. **Default Values** (lowest precedence)\n\nThis means environment variables will always override values from other sources.\n\n##### Reasoning for this Precedence Order\n\nThis precedence model was chosen for several important reasons:\n\n1. **Containerization compatibility**: Environment variables are the standard way to configure applications in containerized environments like Docker and Kubernetes. Having them at the highest precedence ensures compatibility with modern deployment practices.\n\n2. **Operational control**: System administrators and DevOps teams can set environment variables to enforce certain behaviors without worrying about code accidentally or intentionally overriding those settings.\n\n3. **Security boundaries**: Critical security settings like `max_file_size_mb` are better protected when environment variables take precedence, creating a hard boundary that code cannot override.\n\n4. **Debugging convenience**: Setting `MCP_TS_LOG_LEVEL=DEBUG` should reliably increase logging verbosity regardless of other configuration sources, making troubleshooting easier.\n\n5. **Runtime adjustability**: Having explicit updates second in precedence allows for runtime configuration changes that don't persist beyond the current session, unlike environment variables which might be set system-wide.\n\n6. **Fallback clarity**: With this model, it's clear that YAML provides the persistent configuration and defaults serve as the ultimate fallback, leading to predictable behavior.\n\n## Default Configuration Locations\n\nThe server will look for configuration files in the following locations:\n\n1. Path specified by `MCP_TS_CONFIG_PATH` environment variable\n2. Default location: `~/.config/tree-sitter/config.yaml`\n\n## Best Practices\n\n### For Server Users\n\n1. Create a `.treesitter.yaml` file in your project root with your preferred settings\n2. Use the `configure` MCP tool with the path to your YAML file\n3. Adjust cache size based on your project size and available memory\n\n### For Server Developers\n\n1. Use API functions for most operations\n2. Use dependency injection with explicit parameters for new code\n3. Access the dependency container directly only when necessary\n4. Write tests with isolated contexts rather than relying on global state\n\n## Migration from Global CONFIG\n\nIf you have code that previously used the global `CONFIG` variable directly, update it as follows:\n\n**Old code:**\n```python\nfrom mcp_server_tree_sitter.config import CONFIG\n\nmax_depth = CONFIG.language.default_max_depth\n```\n\n**New code:**\n```python\nfrom mcp_server_tree_sitter.api import get_config\n\nconfig = get_config()\nmax_depth = config.language.default_max_depth\n```\n\n### Importing Exceptions\n\nWith the dependency injection approach, exceptions must be imported explicitly. For example, if using `SecurityError` or `FileAccessError`:\n\n```python\nfrom mcp_server_tree_sitter.exceptions import SecurityError, FileAccessError\n\n# Now you can use these exceptions in your code\n```\n\nFor tests, create isolated contexts:\n\n```python\nfrom mcp_server_tree_sitter.context import ServerContext\nfrom mcp_server_tree_sitter.config import ConfigurationManager\n\n# Create test context\nconfig_manager = ConfigurationManager()\nconfig_manager.update_value(\"cache.enabled\", False)\ntest_context = ServerContext(config_manager=config_manager)\n\n# Use test context in your function\nresult = my_function(context=test_context)\n```\n"

    "content": "# MCP Tree-sitter Server Diagnostics\n\nThis document describes the diagnostic testing approach for the MCP Tree-sitter Server project.\n\n## Overview\n\nThe diagnostics suite consists of targeted pytest tests that isolate and document specific issues in the codebase. These tests are designed to:\n\n1. Document current behavior with proper pass/fail results\n2. Isolate failure points to specific functions or modules\n3. Provide detailed error information and stack traces\n4. Create a foundation for developing targeted fixes\n\nThe diagnostic framework combines standard pytest behavior with enhanced diagnostic capabilities:\n- Tests properly pass or fail based on assertions\n- Comprehensive diagnostic data is captured for debugging\n- Diagnostic information is saved to JSON for further analysis\n\n## Running Diagnostics\n\nThe Makefile includes several targets for running diagnostics:\n\n```bash\n# Run all diagnostic tests\nmake test-diagnostics\n\n# CI-friendly version (won't fail the build on diagnostic issues)\nmake test-diagnostics-ci\n```\n\nFor running diagnostics alongside regular tests:\n\n```bash\n# Run both regular tests and diagnostics\nmake test-all\n```\n\n## Using the Diagnostic Framework\n\n### Basic Test Structure\n\n```python\nimport pytest\nfrom mcp_server_tree_sitter.testing import diagnostic\n\n@pytest.mark.diagnostic  # Mark the test as producing diagnostic data\ndef test_some_feature(diagnostic):  # Use the diagnostic fixture\n    # Add details to diagnostic data\n    diagnostic.add_detail(\"key\", \"value\")\n    \n    try:\n        # Test your functionality\n        result = some_functionality()\n        \n        # Use standard assertions - the test will fail if they don't pass\n        assert result is not None, \"Result should not be None\"\n        \n    except Exception as e:\n        # Record the error in diagnostic data\n        diagnostic.add_error(\"ErrorType\", str(e))\n        \n        # Add any artifacts you want to save\n        diagnostic.add_artifact(\"error_artifact\", {\"error\": str(e)})\n        \n        # Re-raise to fail the test\n        raise\n```\n\n### Diagnostic Operations\n\nThe `diagnostic` fixture provides several methods:\n\n- `add_detail(key, value)`: Add a key-value pair to diagnostic details\n- `add_error(error_type, message, traceback=None)`: Add an error\n- `add_artifact(name, content)`: Add an artifact (e.g., JSON data)\n- `finalize(status=\"completed\")`: Mark the diagnostic as complete\n\n## Key Issues Identified and Fixed\n\nThe following issues were identified during the diagnostic process and have since been fixed in the current implementation:\n\n### 1. Language Registry Issues (FIXED)\n- `list_languages()` previously returned empty lists despite languages being available\n- Language detection through `install_language()` worked, but languages didn't appear in available lists\n\n### 2. AST Parsing Failures (FIXED)\n- `get_ast()` previously failed with errors when attempting to build the tree\n- Core AST parsing functionality is now operational with efficient cursor-based traversal\n\n### 3. \"Too Many Values to Unpack\" Errors (FIXED)\n- Several analysis functions failed with \"too many values to unpack (expected 2)\"\n- Affected `get_symbols()`, `get_dependencies()`, and `analyze_complexity()`\n- These issues were resolved by fixing query captures handling\n\n### 4. Tree-sitter Language Pack Integration (FIXED)\n- Integration with tree-sitter-language-pack is now complete and stable\n- All supported languages are correctly recognized and available for analysis\n\n## Diagnostic Results\n\nThe diagnostic tests generate detailed JSON result files in the `diagnostic_results` directory with timestamps. These files contain valuable information for debugging:\n\n- Error messages and stack traces\n- Current behavior documentation\n- Environment and configuration details\n- Detailed information about tree-sitter integration\n\nIn addition, the test output includes a diagnostic summary:\n```\n============================== Diagnostic Summary ==============================\nCollected 4 diagnostics, 2 with errors\n-------------------------------- Error Details ---------------------------------\n- /path/to/test.py::test_function\n  Error 1: ErrorType: Error message\n```\n\n## Recommended Debugging Approach\n\n1. Run the diagnostic tests to verify current issues\n   ```\n   make test-diagnostics\n   ```\n\n2. Examine the diagnostic results in the terminal output and the `diagnostic_results` directory\n\n3. Review specific error patterns to identify the root cause:\n   - For unpacking errors, check the query capture processing code\n   - For AST parsing, examine the tree-sitter integration layer\n   - For language registry issues, check the initialization sequence\n\n4. Make targeted fixes to address specific issues, using the diagnostic tests to verify repairs\n\n5. After fixes, run both diagnostics and regular tests to ensure no regressions\n   ```\n   make test-all\n   ```\n\n## Previous Issue Priority (Now Resolved)\n\nThe following priority was used to address the previously identified issues, which have all been resolved:\n\n1. ✅ **Language Registry Issues** - Fixed language listing to enable proper language detection\n2. ✅ **AST Parsing** - Fixed core parsing functionality with efficient cursor-based traversal\n3. ✅ **Query Handling** - Resolved unpacking errors in query captures to enable analysis tools\n4. ✅ **Incremental Improvements** - Core functionality is working correctly and ready for further refinement\n\nAll 90 tests are now passing, including the diagnostic tests.\n\n## Integrating with Development Workflow\n\nDiagnostics should be run:\n- After any significant changes to core tree-sitter integration code\n- Before submitting pull requests that touch language or AST handling\n- When investigating specific failures in higher-level functionality\n- As part of debugging for issues reported by users\n\n## Continuous Integration\n\nFor CI environments, the diagnostic tests have special considerations:\n\n### CI-Friendly Targets\n\nThe Makefile includes CI-friendly targets that won't fail the build due to known issues:\n\n- `make test-diagnostics-ci`: Runs diagnostics but always returns success\n\n### CI Setup Recommendations\n\n1. **Primary CI Pipeline**: Use `make test` for regression testing of working functionality\n   ```yaml\n   test:\n     script:\n       - make test\n   ```\n\n2. **Diagnostic Job**: Add a separate, optional job for diagnostics\n   ```yaml\n   diagnostics:\n     script:\n       - make test-diagnostics-ci\n     artifacts:\n       paths:\n         - diagnostic_results/\n     allow_failure: true\n   ```\n\n## Benefits of the Pytest-based Approach\n\nThe pytest-based diagnostic framework offers significant advantages:\n\n1. **Unified framework**: All tests use pytest with consistent behavior\n2. **Clear pass/fail**: Tests fail when they should, making issues obvious\n3. **Rich diagnostics**: Detailed diagnostic information is still collected\n4. **Standard integration**: Works with pytest's fixtures, plugins, and reporting\n\n## Future Improvements\n\nIn the future, we plan to:\n\n1. Enhance the diagnostic plugin with more features\n2. Integrate with CI/CD pipelines for better reporting\n3. Add automatic visualization of diagnostic data\n4. Improve the organization of diagnostic tests\n"

    "content": "# Logging Configuration Guide\n\nThis document explains how logging is configured in the MCP Tree-sitter Server and how to control log verbosity using environment variables.\n\n## Environment Variable Configuration\n\nThe simplest way to control logging verbosity is by setting the `MCP_TS_LOG_LEVEL` environment variable:\n\n```bash\n# Enable detailed debug logging\nexport MCP_TS_LOG_LEVEL=DEBUG\n\n# Use normal informational logging\nexport MCP_TS_LOG_LEVEL=INFO\n\n# Only show warning and error messages\nexport MCP_TS_LOG_LEVEL=WARNING\n```\n\n## Log Level Values\n\nThe following log level values are supported:\n\n| Level | Description |\n|-------|-------------|\n| DEBUG | Most verbose, includes detailed diagnostic information |\n| INFO | Standard informational messages |\n| WARNING | Only warning and error messages |\n| ERROR | Only error messages |\n| CRITICAL | Only critical failures |\n\n## How Logging Is Configured\n\nThe logging system follows these principles:\n\n1. **Early Environment Variable Processing**: Environment variables are processed at the earliest point in the application lifecycle\n2. **Root Logger Configuration**: The package root logger (`mcp_server_tree_sitter`) is configured based on the environment variable value\n3. **Logger Hierarchy**: Levels are set _only_ on the root package logger, allowing child loggers to inherit properly\n4. **Handler Synchronization**: Handler levels are synchronized to match their logger's effective level\n5. **Consistent Propagation**: Log record propagation is preserved throughout the hierarchy\n\n## Using Loggers in Code\n\nWhen adding logging to code, use the centralized utility function:\n\n```python\nfrom mcp_server_tree_sitter.bootstrap import get_logger\n\n# Create a properly configured logger\nlogger = get_logger(__name__)\n\n# Use standard logging methods\nlogger.debug(\"Detailed diagnostic information\")\nlogger.info(\"Standard information\")\nlogger.warning(\"Warning message\")\nlogger.error(\"Error message\")\n```\n\n> **Note**: For backwards compatibility, you can also import from `mcp_server_tree_sitter.logging_config`, but new code should use the bootstrap module directly.\n\nThe `get_logger()` function respects the logger hierarchy and only sets explicit levels on the root package logger, allowing proper level inheritance for all child loggers.\n\n## Dynamically Changing Log Levels\n\nLog levels can be updated at runtime using:\n\n```python\nfrom mcp_server_tree_sitter.bootstrap import update_log_levels\n\n# Set to debug level\nupdate_log_levels(\"DEBUG\")\n\n# Or use numeric values\nimport logging\nupdate_log_levels(logging.INFO)\n```\n\nThis will update _only_ the root package logger and its handlers while maintaining the proper logger hierarchy. Child loggers will automatically inherit the new level.\n\n> **Note**: You can also import these functions from `mcp_server_tree_sitter.logging_config`, which forwards to the bootstrap module for backwards compatibility.\n\n## Command-line Configuration\n\nWhen running the server directly, you can use the `--debug` flag:\n\n```bash\npython -m mcp_server_tree_sitter --debug\n```\n\nThis flag sets the log level to DEBUG both via environment variable and direct configuration, ensuring consistent behavior.\n\n## Persistence of Log Levels\n\nLog level changes persist through the current server session, but environment variables must be set before the server starts to ensure they are applied from the earliest initialization point. Environment variables always take highest precedence in the configuration hierarchy.\n\n## How Logger Hierarchy Works\n\nThe package uses a proper hierarchical logger structure following Python's best practices:\n\n- `mcp_server_tree_sitter` (root package logger) - **only logger with explicitly set level**\n  - `mcp_server_tree_sitter.config` (module logger) - **inherits level from parent**\n  - `mcp_server_tree_sitter.server` (module logger) - **inherits level from parent**\n  - etc.\n\n### Level Inheritance\n\nIn Python's logging system:\n- Each logger maintains its own level setting\n- Child loggers inherit levels from parent loggers **unless** explicitly set\n- Log **records** (not levels) propagate up the hierarchy if `propagate=True`\n- The effective level of a logger is determined by its explicit level, or if not set, its nearest ancestor with an explicit level\n\nSetting `MCP_TS_LOG_LEVEL=DEBUG` sets the root package logger's level to DEBUG, which affects all child loggers that don't have explicit levels. Our implementation strictly adheres to this principle and avoids setting individual logger levels unnecessarily.\n\n### Handler vs. Logger Levels\n\nThere are two separate level checks in the logging system:\n\n1. **Logger Level**: Determines if a message is processed by the logger\n2. **Handler Level**: Determines if a processed message is output by a specific handler\n\nOur system synchronizes handler levels with their corresponding logger's effective level (which may be inherited). This ensures that messages that pass the logger level check also pass the handler level check.\n\n## Troubleshooting\n\nIf logs are not appearing at the expected level:\n\n1. Ensure the environment variable is set before starting the server\n2. Verify the log level was applied to the root package logger (`mcp_server_tree_sitter`)\n3. Check that handler levels match their logger's effective level\n4. Verify that log record propagation is enabled (`propagate=True`)\n5. Use `logger.getEffectiveLevel()` to check the actual level being used by any logger\n6. Remember that environment variables have the highest precedence in the configuration hierarchy\n\n## Implementation Details\n\nThe logging system follows strict design requirements:\n\n1. **Environment Variable Processing**: Environment variables are processed at the earliest point in the application lifecycle, before any module imports\n2. **Root Logger Configuration**: Only the package root logger has its level explicitly set\n3. **Handler Synchronization**: Handler levels are synchronized with their logger's effective level\n4. **Propagation Preservation**: Log record propagation is enabled for consistent behavior\n5. **Centralized Configuration**: All logging is configured through the `logging_config.py` module\n6. **Configuration Precedence**: Environment variables > Explicit updates > YAML config > Defaults\n\nFor the complete implementation details, see the `bootstrap/logging_bootstrap.py` module source code.\n\n## Bootstrap Architecture\n\nThe logging system is now implemented using a bootstrap architecture for improved dependency management:\n\n1. The canonical implementation of all logging functionality is in `bootstrap/logging_bootstrap.py`\n2. This module is imported first in the package's `__init__.py` before any other modules\n3. The module has minimal dependencies to avoid import cycles\n4. All other modules import logging utilities from the bootstrap module\n\n### Why Bootstrap?\n\nThe bootstrap approach solves several problems:\n\n1. **Import Order**: Ensures logging is configured before any other modules are imported\n2. **Avoiding Redundancy**: Provides a single canonical implementation of logging functionality\n3. **Dependency Management**: Prevents circular imports and configuration issues\n4. **Consistency**: Ensures all modules use the same logging setup\n\n### Migration from logging_config.py\n\nFor backwards compatibility, `logging_config.py` still exists but now forwards all imports to the bootstrap module. Existing code that imports from `logging_config.py` will continue to work, but new code should import directly from the bootstrap module.\n\n```python\n# Preferred for new code\nfrom mcp_server_tree_sitter.bootstrap import get_logger, update_log_levels\n\n# Still supported for backwards compatibility\nfrom mcp_server_tree_sitter.logging_config import get_logger, update_log_levels\n```\n"

    "content": "# Requirements for Correct Logging Behavior in MCP Tree-sitter Server\n\nThis document specifies the requirements for implementing correct logging behavior in the MCP Tree-sitter Server, with particular focus on ensuring that environment variables like `MCP_TS_LOG_LEVEL=DEBUG` work as expected.\n\n## Core Requirements\n\n### 1. Environment Variable Processing\n\n- Environment variables MUST be processed before any logging configuration is applied\n- The system MUST correctly parse `MCP_TS_LOG_LEVEL` and convert it to the appropriate numeric logging level\n- Environment variable values MUST take precedence over hardcoded defaults and other configuration sources\n\n```python\n# Example of correct implementation\ndef get_log_level_from_env() -> int:\n    env_level = os.environ.get(\"MCP_TS_LOG_LEVEL\", \"INFO\").upper()\n    return LOG_LEVEL_MAP.get(env_level, logging.INFO)\n```\n\n### 2. Root Logger Configuration\n\n- `logging.basicConfig()` MUST use the level derived from environment variables\n- Root logger configuration MUST happen early in the application lifecycle, before other modules are imported\n- Root logger handlers MUST be configured with the same level as the logger itself\n\n```python\n# Example of correct implementation\ndef configure_root_logger() -> None:\n    log_level = get_log_level_from_env()\n    \n    # Configure the root logger with proper format and level\n    logging.basicConfig(\n        level=log_level,\n        format=\"%(asctime)s - %(name)s - %(levelname)s - %(message)s\"\n    )\n    \n    # Ensure the root logger for our package is also set correctly\n    pkg_logger = logging.getLogger(\"mcp_server_tree_sitter\")\n    pkg_logger.setLevel(log_level)\n    \n    # Ensure all handlers have the correct level\n    for handler in logging.root.handlers:\n        handler.setLevel(log_level)\n    \n    # Ensure propagation is preserved\n    pkg_logger.propagate = True\n```\n\n### 3. Package Logger Hierarchy\n\n- The main package logger (`mcp_server_tree_sitter`) MUST be explicitly set to the level from environment variables\n- **DO NOT** explicitly set levels for all individual loggers in the hierarchy unless specifically needed\n- Log record propagation MUST be preserved (default `propagate=True`) to ensure messages flow up the hierarchy\n- Child loggers SHOULD inherit the effective level from their parents by default\n\n```python\n# INCORRECT approach - setting levels for all loggers\ndef get_logger(name: str) -> logging.Logger:\n    logger = logging.getLogger(name)\n    \n    # Setting levels for all package loggers disrupts hierarchy\n    if name.startswith(\"mcp_server_tree_sitter\"):\n        logger.setLevel(get_log_level_from_env())\n    \n    return logger\n\n# CORRECT approach - respecting logger hierarchy\ndef get_logger(name: str) -> logging.Logger:\n    logger = logging.getLogger(name)\n    \n    # Only set the level explicitly for the root package logger\n    if name == \"mcp_server_tree_sitter\":\n        logger.setLevel(get_log_level_from_env())\n    \n    return logger\n```\n\n### 4. Handler Configuration\n\n- Every logger with handlers MUST have those handlers' levels explicitly set to match the logger level\n- New handlers created during runtime MUST inherit the appropriate level setting\n- Handler formatter configuration MUST be consistent to ensure uniform log output\n\n```python\n# Example of correct handler synchronization\ndef update_handler_levels(logger: logging.Logger, level: int) -> None:\n    for handler in logger.handlers:\n        handler.setLevel(level)\n```\n\n### 5. Configuration Timing\n\n- Logging configuration MUST occur before any module imports that might create loggers\n- Environment variable processing MUST happen at the earliest possible point in the application lifecycle\n- Any dynamic reconfiguration MUST update both logger and handler levels simultaneously\n\n### 6. Level Update Mechanism\n\n- When updating log levels, the system MUST update the root package logger level\n- The system MUST update handler levels to match their logger levels\n- The system SHOULD preserve the propagation setting when updating loggers\n\n```python\n# Example of correct level updating\ndef update_log_levels(level_name: str) -> None:\n    level_value = LOG_LEVEL_MAP.get(level_name.upper(), logging.INFO)\n    \n    # Update root package logger\n    pkg_logger = logging.getLogger(\"mcp_server_tree_sitter\")\n    pkg_logger.setLevel(level_value)\n    \n    # Update all handlers on the package logger\n    for handler in pkg_logger.handlers:\n        handler.setLevel(level_value)\n    \n    # Update existing loggers in our package\n    for name in logging.root.manager.loggerDict:\n        if name == \"mcp_server_tree_sitter\" or name.startswith(\"mcp_server_tree_sitter.\"):\n            logger = logging.getLogger(name)\n            logger.setLevel(level_value)\n            \n            # Update all handlers for this logger\n            for handler in logger.handlers:\n                handler.setLevel(level_value)\n            \n            # Preserve propagation\n            logger.propagate = True\n```\n\n## Implementation Requirements\n\n### 7. Logging Utility Functions\n\n- Helper functions MUST be provided for creating correctly configured loggers\n- Utility functions MUST ensure consistent behavior across different modules\n- These utilities MUST respect Python's logging hierarchy where each logger maintains its own level\n\n### 8. Error Handling\n\n- The system MUST handle invalid log level strings in environment variables gracefully\n- Default fallback values MUST be used when environment variables are not set\n- When importing logging utilities fails, modules SHOULD fall back to standard logging\n\n```python\n# Example of robust logger acquisition with fallback\ntry:\n    from ..logging_config import get_logger\n    logger = get_logger(__name__)\nexcept (ImportError, AttributeError):\n    # Fallback to standard logging\n    import logging\n    logger = logging.getLogger(__name__)\n```\n\n### 9. Module Structure\n\n- The `logging_config.py` module MUST be designed to be imported before other modules\n- The module MUST automatically configure the root logger when imported\n- The module MUST provide utility functions for getting loggers and updating levels\n\n## Documentation Requirements\n\n### 10. Documentation\n\n- Documentation MUST explain how to use environment variables to control logging\n- Documentation MUST provide examples for common logging configuration scenarios\n- Documentation MUST explain the logger hierarchy and level inheritance\n- Documentation MUST clarify that log records (not levels) propagate up the hierarchy\n\n## Testing Requirements\n\n### 11. Testing\n\n- Tests MUST verify that environment variables are correctly processed\n- Tests MUST verify that logger levels are correctly inherited in the hierarchy\n- Tests MUST verify that handler levels are synchronized with logger levels\n- Tests MUST verify that log messages flow up the hierarchy as expected\n\n## Expected Behavior\n\nWhen all these requirements are satisfied, setting `MCP_TS_LOG_LEVEL=DEBUG` will properly increase log verbosity throughout the application, allowing users to see detailed debug information for troubleshooting.\n"

    "content": "# Tree-sitter Type Safety Guide\n\nThis document explains our approach to type safety when interfacing with the tree-sitter library and why certain type-checking suppressions are necessary.\n\n## Background\n\nThe MCP Tree-sitter Server maintains type safety through Python's type hints and mypy verification. However, when interfacing with external libraries like tree-sitter, we encounter challenges:\n\n1. Tree-sitter's Python bindings have inconsistent API signatures across versions\n2. Tree-sitter objects don't always match our protocol definitions\n3. The library may work at runtime but fail static type checking\n\n## Type Suppression Strategy\n\nWe use targeted `# type: ignore` comments to handle specific scenarios where mypy can't verify correctness, but our runtime code handles the variations properly.\n\n### Examples of Necessary Type Suppressions\n\n#### Parser Interface Variations\n\nSome versions of tree-sitter use `set_language()` while others use `language` as the attribute/method:\n\n```python\ntry:\n    parser.set_language(safe_language)  # type: ignore\nexcept AttributeError:\n    if hasattr(parser, 'language'):\n        # Use the language method if available\n        parser.language = safe_language  # type: ignore\n    else:\n        # Fallback to setting the attribute directly\n        parser.language = safe_language  # type: ignore\n```\n\n#### Node Handling Safety\n\nFor cursor navigation and tree traversal, we need to handle potential `None` values:\n\n```python\ndef visit(node: Optional[Node], field_name: Optional[str], depth: int) -> bool:\n    if node is None:\n        return False\n    # Continue with node operations...\n```\n\n## Guidelines for Using Type Suppressions\n\n1. **Be specific**: Always use `# type: ignore` on the exact line with the issue, not for entire blocks or files\n2. **Add comments**: Explain why the suppression is necessary\n3. **Try alternatives first**: Only use suppressions after trying to fix the actual type issue\n4. **Include runtime checks**: Always pair suppressions with runtime checks (try/except, if hasattr, etc.)\n\n## Our Pattern for Library Compatibility\n\nWe follow a consistent pattern for tree-sitter API compatibility:\n\n1. **Define Protocols**: Use Protocol classes to define expected interfaces\n2. **Safe Type Casting**: Use wrapper functions like `ensure_node()` to safely cast objects\n3. **Feature Detection**: Use `hasattr()` checks before accessing attributes\n4. **Fallback Mechanisms**: Provide multiple ways to accomplish the same task\n5. **Graceful Degradation**: Handle missing features by providing simplified alternatives\n\n## Testing Approach\n\nEven with type suppressions, we ensure correctness through:\n\n1. Comprehensive test coverage for different tree-sitter operations\n2. Tests with and without tree-sitter installed to verify fallback mechanisms\n3. Runtime verification of object capabilities before operations\n\n## When to Update Type Suppressions\n\nReview and potentially remove type suppressions when:\n\n1. Upgrading minimum supported tree-sitter version\n2. Refactoring the interface to the tree-sitter library\n3. Adding new wrapper functions that can handle type variations\n4. Improving Protocol definitions to better match runtime behavior\n\nBy following these guidelines, we maintain a balance between static type safety and runtime flexibility when working with the tree-sitter library.\n"
