Nothing serious here today

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

SendSeven Messaging — questions

Answers built from our own checks of this server.

Why is there no tool list for SendSeven Messaging?

The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.

Is SendSeven Messaging working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 62 of 62 checks got a reply (100.0%), average response time 264 ms. The bar chart above shows every period we have measured.

How do I connect SendSeven Messaging?

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. You will need your own key: it refuses anonymous clients.

Does SendSeven Messaging need an API key?

Yes. Every time we knock, SendSeven Messaging answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is SendSeven Messaging?

It answers our handshake in 264 ms on average, which is faster than 58% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is SendSeven Messaging open source?

Yes — it is published under the MIT licence, written in TypeScript 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.
