For operators of compatible public HTTPS MCP endpoints. Checkout first verifies a JSON or SSE tools/list response, including MCP initialize/session handshakes. Endpoints requiring authentication, redirects, legacy GET-only SSE, or paginated tool lists are not supported by this plan. Need help confirming fit or testing your alert destination? Email the endpoint to info@dominionobservatory.com.
Email alerts go to your billing email, with an optional webhook destination. Detected changes include old and new manifest hashes and a summary. Manifest contents and change history are public; do not submit private endpoints, access tokens, or confidential tool definitions.
