Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

ask
ask_question
Ask one yes/no style question about the current puzzle. The AI host answers with one of four judgments: 是(Yes) / 不是(No) / 是也不是(Both) / 没有关系(Irrelevant), plus solve progress (0-100).
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 274 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 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 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 274 ms on average, which is faster than 50% 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 53 times in the last week. Week over week that is -83%. 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?
Yes — it is published under the MIT licence, written in JavaScript and 1 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.
