Mailcheck: Email Open & Click Tracker — questions

Answers built from our own checks of this server.

Why is there no tool list for Mailcheck: Email Open & Click Tracker?

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 Mailcheck: Email Open & Click Tracker working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 84 of 84 checks got a reply (100.0%), average response time 129 ms. The bar chart above shows every period we have measured.

How do I connect Mailcheck: Email Open & Click Tracker?

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. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.

How do you sign in to Mailcheck: Email Open & Click Tracker?

No API key is involved. Mailcheck: Email Open & Click Tracker answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.

How fast is Mailcheck: Email Open & Click Tracker?

It answers our handshake in 129 ms on average, which is faster than 86% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
