Can I use authentication with remote MCP servers?

Yes, this skill provides implementation patterns for Bearer tokens and full OAuth flows (GitHub, Google) to ensure only authorized users can trigger your tools.

How do I fix the '404 Not Found' error when connecting to Claude?

This is usually caused by a URL path mismatch. Ensure the URL in your Claude config (e.g., ending in /sse) matches exactly what is defined in your Worker's fetch handler.

What is the difference between SSE and Streamable HTTP?

SSE is the legacy standard for wide compatibility, while Streamable HTTP is the 2025 standard that uses a single endpoint for better performance and simplified architecture.

What are the latest 2025 MCP features included?

The skill includes support for MCP Elicitation (interactive user input), Code Mode (type-safe generated APIs), and MCPClientManager for advanced connection handling.

Why should I use Cloudflare for my MCP server?

Cloudflare is the only platform with official remote MCP support, enabling Claude to access your tools securely over the internet rather than just locally.
