N3mo MCP Server

A structural code intelligence layer that transforms source code into a queryable knowledge graph for search, impact analysis, and AI-powered development. It runs locally over stdio via the published package.

People who work with ci cd, code intelligence and impact analysis and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install N3mo

Claude Code

claude mcp add rajx-dev-n3mo -- uvx n3mo

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "rajx-dev-n3mo": {
      "command": "uvx",
      "args": [
        "n3mo"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license no standard license detected - usage rights unclear; check the repo before commercial use

pypi package n3mo - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.RajX-dev is GitHub-verified and matches the repo owner
