Step-by-step

  1. Edit mcp_config.json
    Add the serverUrl config above to ~/.codeium/windsurf/mcp_config.json and refresh in Cascade.
  2. Authorize
    On first use your client opens a Cloudflare OAuth consent screen โ€” approve it and tools become available.
  3. Verify
    Verify in the browser: paste https://radar.mcp.cloudflare.com/mcp into remotemcp.net/inspector and run initialize + tools/list.

Troubleshooting OAuth / 401

  • A 401 Unauthorized on first connect is normal โ€” the endpoint is OAuth-protected; let Windsurf finish the browser consent flow.
  • If the consent window never opens, remove and re-add the server, then retry.
  • Check the exact challenge at our OAuth debugger.
  • Run the live endpoint through the online inspector to see the raw JSON-RPC exchange.
