Qtcl MCP Server — questions

Answers built from our own checks of this server.

Is Qtcl MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 451 ms. The bar chart above shows every period we have measured.
The registry lists Qtcl MCP Server as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Qtcl MCP Server?
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 is a remote server, so there is nothing to install — the client connects to the address.
Does Qtcl MCP Server need an API key?
No. Qtcl MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.
Is Qtcl MCP Server open source?
Yes — it is published under the Apache-2.0 licence and 0 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.
