Code Guardian runs on your own machine — the client starts it, so there is no endpoint to ping. 215 installs a week from pypi. Last commit 16 Oct 2026.

Safe to run? Will it work? Is it complete? A deterministic A-F grade for a repo, without running it.

Nothing serious here today

Today is the operative word: we check Code Guardian every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This one needs environment variables set before it will start: CODE_GUARDIAN_LLM_URL (Optional: local model for the explain tool (Ollama /api/chat or an OpenAI-compatible /v1/chat/completions URL)), CODE_GUARDIAN_LLM_MODEL (Optional: model name for the explain tool). The author declared them in the registry entry; get the values from the project itself.

Code Guardian — questions

Answers built from our own checks of this server.

Why is there no uptime for Code Guardian?

Code Guardian 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 code-guardian-mcp was installed 215 times last week.

How do I connect Code Guardian?

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 code-guardian-mcp straight from pypi; nothing to host, nothing to sign up for.

How many people use Code Guardian?

The pypi package code-guardian-mcp was installed 215 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Code Guardian open source?

Yes — it is published under the MIT licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
