Existing requests sent to /sse return a 410 Gone response header containing the server's updated /mcp URL, which is displayed in most MCP client connection errors. Users must update their MCP client configuration URLs from /sse to /mcp (e.g., https://docs.mcp.cloudflare.com/mcp ). Clients originally authenticated via /sse will prompt users to sign in again. Clients already using /mcp are unaffected.","sponsors":[]}
