Free for 1 server

Know the moment your MCP server breaks

MCP server monitoring that checks your server the way an AI app uses it: a full QA test every hour once you prove it's yours, and on Pro an up check every 5 minutes. When something goes wrong, you get one email that says what happened, what it means and what to do. When it's fixed, you get one more.

What Monitor watches

Is it up?A quick check that runs no tools: every hour, or every 5 minutes on Pro for a server you own. After 2 failed checks in a row, you get a "Down" email; when it answers again, a "Back up" email with how long it was down.

The full QA testEvery hour on a server you own, every 6 hours otherwise. The same test as the free one: connection, MCP version, tool descriptions and inputs, safety labels, hidden instructions, bad-input handling, leaked secrets, speed, login setup, resources and prompts.

Score dropsWhen the score falls by 5 points or more, with exactly which checks got worse.

Tool changesA tool added, removed or renamed, an input or required field that changed, a safety label that flipped: the exact before and after, even if you didn't change it yourself.

Answers, not just "up"A server can answer and still be broken. You hear when a tool's answer changes shape, or it starts sending back a sign-in page, nothing at all, or far too much.

Login, MCP version, certificateWhen it suddenly asks for a login or its login setup breaks, when the MCP version it speaks changes, and 14 days before its security certificate ends.

SlowWhen it takes 3 seconds or more to start and 3 times longer than usual, 2 checks in a row.

SecurityA hidden instruction that appears in a tool description, or a secret that starts showing up in an error message, and the moment it's gone again.

Gentle until you prove it's yoursWe never test a server hard unless its owner says so. Publish a short code on your server or in your DNS, it takes a minute, and you get full speed. If many people watch one server, it still gets one test.

Safe, alwaysOnly tools labeled read-only are ever run, and never anything that sounds like it deletes. Monitor never changes your data.

What an alert looks like

This is a real Monitor email, for our own test server that we switched off on purpose.

Questions

Does paying change my score in the directory?

No, never. Every server gets the same test, and scores are never changed for money. The directory rules

Can Monitor break or change my server?

No. It only runs tools your server labels read-only, and only when their name, description and inputs agree. The 5-minute check runs no tools at all.

My server needs a login. Does Monitor work?

Yes. On Pro, prove the server is yours, then save a key on its page and every test uses it. It's stored encrypted, sent only to your server, and never shown again. Use a key that can only read.

What do you keep about me?

Your email, your server's link and its test history. No AI reads any of it. Privacy

How is this different from an uptime checker?

An uptime checker tells you your server answered. QAmcp tells you an AI can still use it: tools, inputs, safety labels and answers, all compared with what your server normally does.
