Nothing serious here today

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

Rails MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Rails MCP?

Rails MCP 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 rails-mcp was installed 106 times last week.

How do I connect Rails MCP?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls rails-mcp straight from pypi; nothing to host, nothing to sign up for.

How many people use Rails MCP?

The pypi package rails-mcp was installed 106 times in the last week. Week over week that is +25%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Rails MCP 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.
