Overview
What is mcp-codebase-index?
A structural codebase indexer with an MCP server for AI-assisted development. It parses source files into structural metadata (functions, classes, imports, dependency graphs, call chains) and exposes 18 query tools via the Model Context Protocol, enabling Claude Code and other MCP clients to navigate codebases efficiently without reading entire files. Requires Python 3.11+ and has zero runtime dependencies.
How to use mcp-codebase-index?
Install via pip install "mcp-codebase-index[mcp]", then set the PROJECT_ROOT environment variable and run as a console script (mcp-codebase-index) or Python module (python -m mcp_codebase_index.server). Configure with Claude Code (.mcp.json) or OpenClaw (openclaw.json) by specifying the command and environment variable.
