Why use Cloudflare for MCP servers?

Cloudflare is the only platform providing official remote MCP support, offering global low-latency deployment and built-in security features like Workers OAuth.

What is the difference between SSE and Streamable HTTP?

SSE is the legacy transport for wide compatibility, while Streamable HTTP is the 2025 standard offering simplified single-endpoint architecture and better performance.

Does this skill support user input during tool execution?

Yes, it includes guidance for MCP Elicitation, a feature that allows servers to request interactive input or confirmations from the user during execution.

How do I fix 404 errors when connecting Claude to my worker?

404 errors are usually caused by URL path mismatches; ensure your client configuration URL exactly matches the base path handled by serveSSE() or serve() in your worker code.
