Rigor MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Rigor MCP?

Rigor 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 rigor-mcp was installed 132 times last week.

How do I connect Rigor MCP?

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

How many people use Rigor MCP?

The pypi package rigor-mcp was installed 132 times in the last week. Week over week that is -11%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Rigor MCP open source?

Yes — it is published under the MIT licence, written in Python and 1 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.
