What is Punycode ACE prefix, host discarded mostly used for?
Its tools cluster around status and agent. 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 Punycode ACE prefix, host discarded working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 89 of 92 checks got a reply (96.7%), average response time 39 ms. The bar chart above shows every period we have measured.
How do I connect Punycode ACE prefix, host discarded?
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 Punycode ACE prefix, host discarded need an API key?
No. Punycode ACE prefix, host discarded completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 31 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Punycode ACE prefix, host discarded?
It answers our handshake in 39 ms on average, which is faster than 98% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Punycode ACE prefix, host discarded open source?
We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
