MailByGet — questions

Answers built from our own checks of this server.

What can MailByGet do?
It exposes 3 tools, read directly from the server on our last check. Among them: create_inbox, list_messages, read_message. 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 MailByGet 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 429 ms. The bar chart above shows every period we have measured.
How do I connect MailByGet?
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 MailByGet need an API key?
No. MailByGet 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 MailByGet?
It answers our handshake in 429 ms on average, which is faster than 30% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
