Well-known MCP descriptor
What it means
Your site publishes an MCP server descriptor at /.well-known/mcp.json.
Why it matters
A well-known MCP descriptor lets agents discover your MCP server's transport, capabilities, and tool registry without manual configuration.
✗
What's wrong
No /.well-known/mcp.json endpoint. Agents must guess your MCP server's location and capabilities.
✓
What's right
/.well-known/mcp.json returns JSON with server info, transport type, and tool registry.
