Kawaa email verification — questions

Answers built from our own checks of this server.

Is Kawaa email verification working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 90 checks got a reply (100.0%), average response time 710 ms. The bar chart above shows every period we have measured.

How do I connect Kawaa email verification?

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 Kawaa email verification need an API key?

No. Kawaa email verification completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.

How fast is Kawaa email verification?

It answers our handshake in 710 ms on average, which is faster than 18% 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.
