What the code does

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command python/src/pyscn/main.py:67
        result = subprocess.run(
            initPath := filepath.Join(packagePath, name)

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add pyscn -- uvx pyscn-mcp
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "pyscn": {
      "args": [
        "pyscn-mcp"
      ],
      "command": "uvx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.pyscn]
command = "uvx"
args = ["pyscn-mcp"]
.cursor/mcp.json
{
  "mcpServers": {
    "pyscn": {
      "args": [
        "pyscn-mcp"
      ],
      "command": "uvx"
    }
  }
}
.vscode/mcp.json
{
  "mcpServers": {
    "pyscn": {
      "args": [
        "pyscn-mcp"
      ],
      "command": "uvx"
    }
  }
}

This one needs environment variables set before it will start: PYSCN_CONFIG (Path to a .pyscn.toml configuration file. Defaults to the usual config discovery (.pyscn.toml, then pyproject.toml) starting from the analyzed directory.). The author declared them in the registry entry; get the values from the project itself.

pyscn — questions

Answers built from our own checks of this server.

Why is there no uptime for pyscn?
pyscn runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package pyscn-mcp was installed 1 399 times last week.
How do I connect pyscn?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls pyscn-mcp straight from pypi; nothing to host, nothing to sign up for.
How many people use pyscn?
The pypi package pyscn-mcp was installed 1 399 times in the last week. Week over week that is +24%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is pyscn open source?
Yes — it is published under the MIT licence, written in Go, 1 068 stars on GitHub and 8 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
