Codemap

codemap is a blazing fast Rust CLI tool and MCP (Model Context Protocol) server for analyzing codebases. It extracts definitions (functions, classes, structs) from source code using Tree-sitter and outputs them in a structured format (Markdown or JSON) optimized for LLM context.

Features

• Fast: Built with Rust and Rayon for parallel processing.
• Accurate: Uses Tree-sitter for robust parsing.
• Structured Output: Generates concise Markdown summaries of your code structure.
• MCP Support: Runs as an MCP server to provide context to LLMs like Claude or Cursor.
• Language Support: Rust, Python, TypeScript, TSX.

Installation

cargo install --path .

Usage

CLI

Analyze a directory and output Markdown:

codemap src/

Output JSON:

codemap src/ --format json
