MCP server at https://resend.com/.well-known/mcp.json

2/2 tests passed

Looking at these test results, this appears to be a web application returning HTML content rather than a proper MCP server. The responses show HTML DOCTYPE and web page content instead of JSON-RPC 2.0 protocol responses that MCP requires.
