How we check

Up means the MCP handshake and the tool list worked, or the server asked for sign-in or payment.

Checks come from our server, about every 10 hours for this listing over the last 7 days. A failure can also mean the service blocks our checks. Two failed checks in a row count as an outage, which ends at the next passing check.

If you think a check is wrong, contact hello@toolvet.app. More on how we check and score.
