Senders MCP — questions

Answers built from our own checks of this server.

Is Senders MCP working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 88 of 92 checks got a reply (95.7%), average response time 379 ms. The bar chart above shows every period we have measured.

Is Senders MCP still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Senders MCP?

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 Senders MCP need an API key?

No. Senders MCP 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 Senders MCP?

It answers our handshake in 379 ms on average, which is faster than 42% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
