Nothing serious here today

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

Polygon — questions

Answers built from our own checks of this server.

Why is there no uptime for Polygon?

Polygon 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 mcparmory-polygon was installed 217 times last week.

How do I connect Polygon?

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 mcparmory-polygon straight from pypi; nothing to host, nothing to sign up for.

How many people use Polygon?

The pypi package mcparmory-polygon was installed 217 times in the last week. Week over week that is +8%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Polygon open source?

We cannot say either way: written in Python, 32 stars on GitHub and 3 open issues, but we could not determine the licence, and without one the code is not open source by default.
