Echo does not always answer

Over the last week it answered 93.1% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Echo — questions

Answers built from our own checks of this server.

What can Echo do?
It exposes 5 tools, read directly from the server on our last check. Among them: echo_beacon, echo_collect_key, echo_order, echo_tts, echo_voices. 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 Echo working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 54 of 58 checks got a reply (93.1%), average response time 625 ms. The bar chart above shows every period we have measured.
How do I connect Echo?
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 Echo need an API key?
No. Echo completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Echo?
It answers our handshake in 625 ms on average, which is faster than 22% 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.
