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 18 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.
