What is the Ast MCP Server?

MCP server that uses TypeScript AST to find which tests are affected by a code change

What it actually does

ast-impact-mapper-mcp is an advanced Model Context Protocol (MCP) server that analyzes your TypeScript/JavaScript codebase using AST parsing (ts-morph) and dependency graph tracing. It helps AI agents (like Claude or Cursor) target only the relevant tests, find dead code, identify circular import dependencies, and trace API mutations.
