Overview

Description from the maker (original English)

Python code analysis for AI agents: complexity, dead code, clones, coupling, and a health score.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Clinics & health

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
You fill in yourself: PYSCN_CONFIG

You need

PyPIPython’s uv installed (for the uvx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "pyscn": {
      "command": "uvx",
      "args": [
        "pyscn-mcp"
      ],
      "env": {
        "PYSCN_CONFIG": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add pyscn --env PYSCN_CONFIG=your-value -- uvx pyscn-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "pyscn": {
      "command": "uvx",
      "args": [
        "pyscn-mcp"
      ],
      "env": {
        "PYSCN_CONFIG": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "pyscn": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "pyscn-mcp"
      ],
      "env": {
        "PYSCN_CONFIG": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

PYSCN_CONFIG env
Path to a .pyscn.toml configuration file. Defaults to the usual config discovery (.pyscn.toml, then pyproject.toml) starting from the analyzed directory.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Common questions

Is pyscn safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.33.1) reached the registry 9 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

Code quality analysis for Python in the age of AI coding.

Building with Cursor, Claude, or ChatGPT? pyscn keeps AI-generated code maintainable with structural analysis.

Quick Start

# Run analysis without installation

uvx pyscn@latest analyze .

or

pipx run pyscn analyze .

Demo

Features

One command scores your whole codebase (0-100 with an A-F grade) and generates an HTML report that shows what to fix first.

pyscn looks at your code from five angles:

🧹 Dead code - unreachable code you can safely delete
📋 Duplicate code - copy-pasted and structurally similar code worth merging (Type 1-4 clone detection)
🌀 Complexity - functions and executable class suites that are hard to read and test (cyclomatic and cognitive complexity)
🔥 Module and directory hotspots - per-file quality and per-directory complexity rollups for prioritizing refactors
🏗️ Architecture - circular imports, layer rule violations (clean / layered / hexagonal / MVC presets), and auto-detected module communities that reveal how your code is actually structured
🧩 Class design - classes that do too much or depend on too much (CBO coupling, LCOM4 cohesion)

100,000+ lines/sec • Built with Go + tree-sitter

Other Languages

pyscn is the Python analyzer of polyscan. For JavaScript, TypeScript, Go, Rust and C++, run:

npx polyscan analyze .

Same five angles, same 0-100 score, one HTML report.

Polyscan for GitHub

Polyscan App files a weekly audit report as a GitHub Issue. Free for public repositories.

AI Agent Integration

pyscn ships Agent Skills that teach AI coding agents when and how to run each analysis: health checks, refactoring, architecture review, and CI-friendly reports.

Agent Skills (Recommended)

uvx add-skills ludo-technologies/pyscn

This installs the Skills into your project. They work with Claude Code, Cursor, Codex, Gemini CLI, and many other agents (add --agent cursor etc. to target one, --global for all projects).

Then just ask your agent:

"Analyze the code quality of the app/ directory"

"Find duplicate code and help me refactor it"

"Show me complex code and help me simplify it"

MCP Server (Optional)

For tighter integration, the bundled pyscn-mcp server exposes the same analyses as MCP tools to Claude Code, Cursor, ChatGPT, and other MCP clients.

Claude Code plugin (sets up the MCP server and the Skills together):

claude plugin marketplace add ludo-technologies/pyscn

claude plugin install pyscn-mcp@pyscn-marketplace

Manual setup for Claude Code:

claude mcp add pyscn-mcp uvx -- pyscn-mcp

Cursor / Claude Desktop: add to your MCP settings (~/.config/claude-desktop/config.json or Cursor settings):

"mcpServers": { "pyscn-mcp": { "command": "uvx", "args": ["pyscn-mcp"], "env": { "PYSCN_CONFIG": "/path/to/.pyscn.toml" } } } }

Dive deeper in mcp/README.md for setup walkthroughs and docs/MCP_INTEGRATION.md for architecture details.

Installation

# Install with pipx (recommended)

pipx install pyscn

Or with uv

uv tool install pyscn

macOS Intel (x86_64): PyPI wheels are built for Apple Silicon only (the Intel wheel was dropped in v1.5.1), so uvx, pipx, uv, and pip cannot install pyscn on Intel Macs. Use brew install pyscn or go install github.com/ludo-technologies/pyscn/cmd/pyscn@latest instead.

Alternative installation methods

Build from source

git clone https://github.com/ludo-technologies/pyscn.git

cd pyscn make build

Go install

go install github.com/ludo-technologies/pyscn/cmd/pyscn@latest

Common Commands

`pyscn analyze`

Run comprehensive analysis with HTML report

pyscn analyze .                              # All analyses with HTML report

pyscn analyze --json . # Generate JSON report pyscn analyze --json --output - . | jq # JSON report on stdout pyscn analyze --json --html --no-open . # JSON and HTML reports from one run pyscn analyze --select complexity . # Only complexity analysis pyscn analyze --select deps . # Only dependency analysis pyscn analyze --select complexity,deps,deadcode . # Multiple analyses pyscn analyze --skip-communities . # Skip module community detection

`pyscn check`

Fast CI-friendly quality gate

pyscn check .                         # Quick pass/fail check

pyscn check --max-complexity 15 . # Custom thresholds pyscn check --max-cycles 0 . # Only allow 0 cycle dependency pyscn check --select deps . # Check only for circular dependencies pyscn check --select di . # Detect DI anti-patterns (opt-in) pyscn check --allow-circular-deps . # Allow circular dependencies (warning only)

`pyscn init`

Create configuration file

pyscn init                         # Generate .pyscn.toml

💡 Run pyscn --help or pyscn --help for complete options

Configuration

Create a .pyscn.toml file or add [tool.pyscn] to your pyproject.toml:

# .pyscn.toml

[complexity] max_complexity = 15

[dead_code] min_severity = "warning"

[output] directory = "reports"

⚙️ Run pyscn init to generate a full configuration file with all available options
