AST MCP Server について

By transforming source code into a queryable Semantic Graph and a structured AST, this tool bridges the gap between "reading text" and "understanding structure." For an AI assistant, it provides the "spatial" awareness needed to navigate deep dependencies without getting lost in

概要

What is AST MCP Server?

AST MCP Server is an MCP (Model Context Protocol) server that provides code structure and semantic analysis capabilities through Abstract Syntax Trees (AST) and Abstract Semantic Graphs (ASG). It supports multiple programming languages (Python, JavaScript, TypeScript, Go, Rust, C/C++, Java) and is compatible with Claude Desktop and other MCP clients.

How to use AST MCP Server?

Requires Python 3.9+ and either uv (recommended) or pip. Clone the repository, run uv sync then uv run build-parsers. Configure Claude Desktop by editing its configuration file and adding an MCP server entry with the absolute path to the server directory. Claude can then use tools like parse_to_ast, generate_asg, analyze_code, etc. to analyze code snippets or local files.

Key features of AST MCP Server

  • Parse code into Abstract Syntax Trees (AST)
  • Generate Abstract Semantic Graphs (ASG) from code
  • Analyze code structure and complexity
  • Support for multiple programming languages
  • Incremental parsing for large files
  • AST diffing to identify code changes
  • Resource caching for improved performance

Use cases of AST MCP Server

  • Analyze code structure in any supported language using Claude Desktop
  • Compare code versions using AST diffing
  • Cache analysis results for repeated queries
  • Use incremental parsing for large files
  • Locate specific nodes in code by line and column

よくある質問

1

What languages does AST MCP Server support?

Python, JavaScript, TypeScript, Go, Rust, C, C++, and Java.

2

Where does data live?

All tool execution happens locally on your machine, with results returned to Claude for interpretation.

3

How do I configure Claude Desktop?

Edit the Claude Desktop configuration file (located at `~/Library/Application Support/claude-desktop/claude_desktop_config.json` on macOS, with similar paths on Linux and Windows) and add the AST MCP server entry with the absolute path to the server directory.

4

What are the prerequisites?

Python 3.9 or higher and the `uv` package manager (recommended) or pip.

5

How do I add support for a new language?

Install the corresponding tree-sitter language package, update the `LANGUAGE_MODULES` dictionary in `build_parsers.py` and `ast_mcp_server/tools.py`, then run `uv run build-parsers`.
