Fix: A .well-known MCP server card is published (SEP-1649)
Web-audit fix skill for the
well-known-mcp-cardcheck (MCP & API, SHOULD).
Goal
Publish an MCP server card at the canonical SEP-1649 path and 301 the legacy aliases to it.
Fix
Publish an MCP server card at /.well-known/mcp/server-card.json (SEP-1649) naming the endpoint, transport, and capabilities: include mcp_endpoint (or url, or transport.endpoint), serverInfo, and the transport type. Serve the legacy pointer paths (/.well-known/mcp, /.well-known/mcp.json, /mcp.json) as 301 redirects to the canonical, never as duplicate inline copies.
