AST MCP Server
MCP server for Abstract Syntax Tree (AST) analysis of source code. Enables AI agents to parse source code into ASTs, query code structure, extract function definitions and class hierarchies, analyze code patterns, and perform structural code analysis — supporting AI-driven code understanding and refactoring workflows.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Local parsing. No credentials. Source code stays local. Low risk.
⚡ Reliability
Best When
A developer building code analysis or refactoring agents needs structural understanding of source code — using AST parsing to extract code structure beyond simple text search.
Avoid When
Simple grep/regex-based code search satisfies your needs. AST parsing adds complexity — evaluate whether structural analysis is actually required.
Use Cases
- • Parsing source code into ASTs from code analysis agents
- • Extracting function signatures and class structures from codebase understanding agents
- • Analyzing code patterns and dependencies from refactoring agents
- • Supporting AI code review with structural code analysis
Not For
- • Runtime debugging (AST is static analysis)
- • Binary/compiled code analysis without source
- • Teams with existing LSP-based tools covering the same functionality
Interface
Authentication
Local code analysis — no authentication required.
Pricing
Free open source AST analysis tool.
Agent Metadata
Known Gotchas
- ⚠ Language support varies — verify which programming languages the AST parser supports
- ⚠ AST structure differs by language and parser version — agents must understand language-specific AST
- ⚠ Large codebases can be slow to parse — implement caching or selective file parsing
- ⚠ Community tool at 30 stars — evaluate maintenance before production dependency
