Pyscn MCP Server

Python code analysis for AI agents: complexity, dead code, clones, coupling, and a health score. It runs locally over stdio via the published package.

People connecting science & health tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Go.

01 · Install Pyscn

before you install - you'll need

PYSCN_CONFIG

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add ludo-technologies-pyscn -- uvx pyscn-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "ludo-technologies-pyscn": {
      "command": "uvx",
      "args": [
        "pyscn-mcp"
      ]
    }
  }
}

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 MIT - declared in the repository

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

registry namespace io.github.ludo-technologies is GitHub-verified and matches the repo owner

06 · Pyscn FAQ

What is Pyscn?

Python code analysis for AI agents: complexity, dead code, clones, coupling, and a health score. It runs locally over stdio via the published package.

Is Pyscn still maintained?

Yes - as of 2026-08-25, its last commit was 2026-08-25 and it shipped 10+ releases in the last 90 days. We re-verify nightly.

How do I install Pyscn?

Run `uvx pyscn-mcp`. The README documents one environment variable (PYSCN_CONFIG) to set first. You can also paste the ready-made client config above.

Does Pyscn run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
