What our free test checks
Our free test: Partly checked
Reads /.well-known/mcp.json and /.well-known/mcp. A valid JSON object is shown as an MCP discovery file. We don’t connect to the server or run a handshake.
Requests (GET only)
/.well-known/mcp.json/.well-known/mcp
Shown in the result as
- MCP discovery file
Our rules
How the test treats protocols
- None of these affects the score. Adoption is still very low, so a missing file is information, not a fault.
- Only GET requests to the store’s own domain, small and short. We never call an endpoint, open a session, send a POST or place an order.
- A file counts only if it is a valid JSON object of the expected shape; a soft 404 page doesn’t count.
- Every request is listed on our crawler page, and you can ask to have your site excluded.
