Tools have disappeared from this server
A tool that vanishes takes a piece of your agent with it, and the change arrives silently. Watch this server and every such change lands in your inbox.

MinuteMail — questions
Answers built from our own checks of this server.
What can MinuteMail do?
It exposes 40 tools, read directly from the server on our last check. Among them: archived.delete, archived.get, archived.list, archived.reactivate, attachments.add, attachments.delete and 34 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 MinuteMail mostly used for?
Its tools cluster around team, attachments and mailboxes. 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 MinuteMail 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 462 ms. The bar chart above shows every period we have measured.
Did MinuteMail ever remove tools?
Yes. mm_add_attachment, mm_add_member, mm_bulk_delete_attachments, mm_bulk_delete_mailboxes and 35 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect MinuteMail?
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 MinuteMail need an API key?
No. MinuteMail completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 40 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is MinuteMail?
It answers our handshake in 462 ms on average, which is faster than 38% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is MinuteMail open source?
Yes — it is published under the MIT licence, written in Go and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
