- Cloudflare MCP servers now only serve /mcp; requests to /sse return 410 Gone with the /mcp URL.
- Clients using an /sse endpoint must update their configuration to the /mcp URL (e.g., https://docs.mcp.cloudflare.com/mcp).
- Existing connections that already use /mcp are unaffected, but sign‑in via /sse will require re‑authentication.
