Nothing serious here today

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

Newsletter — questions

Answers built from our own checks of this server.

Is Newsletter 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 450 ms. The bar chart above shows every period we have measured.

How do I connect Newsletter?

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 Newsletter need an API key?

No. Newsletter 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 Newsletter?

It answers our handshake in 450 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.
