MCP endpoint checker
Does an MCP endpoint answer, and does it need auth?
The check runs on our server. We do not store the domain.
What this checks
MCP (Model Context Protocol) is how AI assistants connect to a tool or data source over the network. This tool probes https://domain/mcp — the path this site's own MCP server and most remote MCP servers use — with a plain GET request, and separately checks /.well-known/oauth-protected-resource for published OAuth discovery metadata (RFC 9728). If your server answers at a different path, such as /mcp/mcp or /sse, this check will not find it.
What to look for
HTTP 404 usually means nothing is mounted at that path. Any other response — including an error code — means something answered, which is as far as this check goes: it never signs in, sends credentials, or calls a tool.
Auth is a good sign here
An endpoint that answers 401 or 403 is telling callers to authenticate before doing anything — that's the expected shape for a real MCP server, not a fault.
