Pmcp — questions

Answers built from our own checks of this server.

Why is there no uptime for Pmcp?
Pmcp runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.
Is Pmcp open source?
Yes — it is published under the MIT licence, written in Rust, 54 stars on GitHub and 8 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
