Email me when this server changes

Name an MCP server and an address. It is checked every hour; you get one email when it stops answering or its tool list changes, and another when it recovers. A server that asks for sign-in counts as answering while a client that has never seen it can still sign in; if that breaks, the email names the step. No password, no GitHub, no card. Free for one server.

Double opt-in. We send one email with a confirmation link (it works for 24 hours). Nothing is watched until it is followed, and every alert has a link to stop.

Privacy. This address is used only to send this confirmation and, if you confirm, alerts about this server. It is never shown on any public page. The server’s public status page names the account by a random handle. See the privacy note and terms; confirming creates a free agentcheck account under them.

More than one server? Starter: 3 servers, checks every 5 minutes, $29/month — from the manage link in any watch email.

For agents: POST /api/v1/watch with {"target": "…", "email": "…"}; GET it for the contract.
