JSON MCP Server

Nothing serious here today

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

JSON — questions

Answers built from our own checks of this server.

Why is there no uptime for JSON?
JSON runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.
Is JSON open source?
We cannot say either way: written in JavaScript and 1 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
