Concurrent-client isolation probe — questions

Answers built from our own checks of this server.

What can Concurrent-client isolation probe do?
It exposes 3 tools, read directly from the server on our last check. Among them: get_verdict, probe_isolation, verify_receipt. 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 Concurrent-client isolation probe working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 339 ms. The bar chart above shows every period we have measured.
How do I connect Concurrent-client isolation probe?
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 Concurrent-client isolation probe need an API key?
No. Concurrent-client isolation probe 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 Concurrent-client isolation probe?
It answers our handshake in 339 ms on average, which is faster than 47% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
