Code Factory MCP Server

An AI agent - or a human developer - can write the code, write the tests, and set the rules used to approve its own work. Everything can turn green while the result still misses the request, leaks another tenant's data, breaks during a retry, damages a migration, or slows down in production. It runs locally over stdio via the published package.

People who work with codex, prompt injection and developer tools and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Code Factory

Claude Code

claude mcp add zrk222-code-factory -- uvx factoryline-code-factory

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "zrk222-code-factory": {
      "command": "uvx",
      "args": [
        "factoryline-code-factory"
      ]
    }
  }
}

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 factoryline-code-factory - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.zrk222 is GitHub-verified and matches the repo owner
