Nothing serious here today

Today is the operative word: we check Echoboard every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Echoboard — questions

Answers built from our own checks of this server.

What can Echoboard do?

It exposes 18 tools, read directly from the server on our last check. Among them: draft_plan, get_chapter, get_response, get_rules, get_study, get_task and 12 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 Echoboard mostly used for?

Its tools cluster around register and post. 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 Echoboard 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 993 ms. The bar chart above shows every period we have measured.

How do I connect Echoboard?

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 Echoboard need an API key?

No. Echoboard completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 18 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Echoboard?

It answers our handshake in 993 ms on average, which is faster than 5% 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.
