Tree-sitter MCP Server
Tree-sitter MCP server enabling AI agents to parse and analyze code using Tree-sitter's language-aware parser — generating syntax trees from source code, querying specific code constructs, extracting function and class definitions, and integrating structured code analysis into agent-driven code review and refactoring workflows across 40+ programming languages.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Local parsing. No credentials. No network. Community MCP. Standard filesystem access.
⚡ Reliability
Best When
An agent needs precise, language-aware code parsing across multiple languages — Tree-sitter provides fast, incremental parsing with pattern matching for 40+ languages.
Avoid When
You need runtime evaluation, semantic type analysis, or work only with languages lacking Tree-sitter grammars.
Use Cases
- • Parsing source code to extract function and class definitions from analysis agents
- • Querying code structure with Tree-sitter patterns from refactoring agents
- • Analyzing code complexity and structure from code review agents
- • Extracting code symbols for navigation from development agents
- • Language-aware code transformation from refactoring agents
- • Building precise code search tools from code intelligence agents
Not For
- • Runtime code execution (Tree-sitter is a parser, not a runtime)
- • Languages not supported by Tree-sitter (check supported language list)
- • Semantic analysis requiring type information (syntactic parsing only)
Interface
Authentication
No authentication — local parsing engine with Tree-sitter library. Language grammars must be available locally.
Pricing
Free open source MCP. Tree-sitter is free and open source. Language grammars may need to be installed separately.
Agent Metadata
Known Gotchas
- ⚠ Tree-sitter grammar must be installed for each language — check supported languages
- ⚠ Tree-sitter query pattern syntax must be learned — not standard regex
- ⚠ Parsing is syntactic only — no semantic type information available
- ⚠ Community MCP from wrale — quality above average for code analysis tools
- ⚠ Large files may be slow to parse — consider chunking for very large codebases
- ⚠ Query patterns vary by language — generalize cautiously across language grammars
