Answers built from our own checks of this server.

What can YarnGPT MCP by Nova (CIVAI) do?

It exposes 2 tools, read directly from the server on our last check. Among them: list_voices, text_to_speech. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is YarnGPT MCP by Nova (CIVAI) working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 89 of 91 checks got a reply (97.8%), average response time 554 ms. The bar chart above shows every period we have measured.

Did YarnGPT MCP by Nova (CIVAI) ever remove tools?

Yes. bgpt_yarngpt is no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

How do I connect YarnGPT MCP by Nova (CIVAI)?

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 is a remote server, so there is nothing to install — the client connects to the address.

Does YarnGPT MCP by Nova (CIVAI) need an API key?

No. YarnGPT MCP by Nova (CIVAI) completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is YarnGPT MCP by Nova (CIVAI)?

It answers our handshake in 554 ms on average, which is faster than 20% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
