MCP Turtle Noir missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

give

give_up_and_reveal

Reveal the hidden solution and end the session. Only allowed once solve progress reaches 60.

start

start_session

Start a new Turtle Soup (lateral thinking puzzle) session. Returns the surface story; the hidden solution stays on the server. Optional filters: region (CN/US/JP), difficulty, keyword.

MCP Turtle Noir — questions

Answers built from our own checks of this server.

What can MCP Turtle Noir do?

It exposes 3 tools, read directly from the server on our last check. Among them: ask_question, give_up_and_reveal, start_session. 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 MCP Turtle Noir working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 325 ms. The bar chart above shows every period we have measured.

How do I connect MCP Turtle Noir?

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 MCP Turtle Noir need an API key?

No. MCP Turtle Noir completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is MCP Turtle Noir?

It answers our handshake in 325 ms on average, which is faster than 43% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use MCP Turtle Noir?

The npm package mcp-turtle-noir was installed 49 times in the last week. Week over week that is -34%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is MCP Turtle Noir open source?

The code is open source: it is published under the MIT licence, written in JavaScript and 1 stars on GitHub. The licence covers the code in the repository, not the hosted service at turtlenoir.com, which runs on its operator's own terms.
