Nothing serious here today

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

Schema — questions

Answers built from our own checks of this server.

Why is there no uptime for Schema?

Schema 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 npm package @rog0x/mcp-schema-tools was installed 30 times last week.

How do I connect Schema?

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 @rog0x/mcp-schema-tools straight from npm; nothing to host, nothing to sign up for.

How many people use Schema?

The npm package @rog0x/mcp-schema-tools was installed 30 times in the last week. Week over week that is +112%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Schema open source?

We cannot say either way: written in TypeScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
