MUDD World Sanctuary missed 2 checks 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.

MUDD World Sanctuary — questions

Answers built from our own checks of this server.

What can MUDD World Sanctuary do?

It exposes 53 tools, read directly from the server on our last check. Among them: blueprint_list, brew, build_invention, buy, buy_ingredient, cancel_gift and 47 more. 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 →

What is MUDD World Sanctuary mostly used for?

Its tools cluster around gift, workshop and codelab. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is MUDD World Sanctuary working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 91 checks got a reply (98.9%), average response time 344 ms. The bar chart above shows every period we have measured.

Did MUDD World Sanctuary ever remove tools?

Yes. gathering_create, gathering_join, gathering_list, say are 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 MUDD World Sanctuary?

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 MUDD World Sanctuary need an API key?

No. MUDD World Sanctuary completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 53 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is MUDD World Sanctuary?

It answers our handshake in 344 ms on average, which is faster than 41% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
