AST MCP Server

Example Use Cases

• 1

  Extract precise code structure (AST) and semantic relationships (ASG) to power code understanding, summarization, or transformation workflows.

• 2

  Analyze code complexity, locate functions/classes, and compute metrics to support refactoring suggestions or automated code review.

• 3

  Incremental parsing, AST diffing, and cached analysis results to efficiently handle large or frequently changing codebases while integrated via MCP.

Description

This server parses code into Abstract Syntax Trees (ASTs) and generates Abstract Semantic Graphs (ASGs) to provide structural and semantic code analysis, including complexity metrics and scope handling. It supports multiple languages (Python and JavaScript), incremental parsing for large files, AST diffing to identify changes, and resource caching for reusable analysis outputs. The server is designed to run locally and integrates with MCP-aware clients (e.g., Claude Desktop) to make analysis tools available in-agent.
