N3Mo

Overview

N3Mo is a Model Context Protocol server that transforms code repositories into queryable symbol graphs, enabling AI assistants to understand and navigate codebases with precision. Any MCP-compatible assistant can invoke N3Mo's tools directly during conversations or agent runs, letting the model decide when detailed code intelligence adds value to its reasoning.

The server runs locally on your machine using the Python package n3mo, installed via uvx n3mo. It requires no authentication and works immediately out of the box, communicating with your MCP client over stdio. The latest release is v2.0.3, maintained at RajX-dev/N3MO on GitHub where the project has 24 stars.

N3Mo belongs in the Development category on mcp.site and integrates with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. Maintainers from RajX-dev are welcome to claim this listing, verify ownership, and ensure the information stays current.
