npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless

You can connect to your MCP server from the Cloudflare AI Playground, which is a remote MCP client:
- Go tohttps://playground.ai.cloudflare.com/
- Enter your deployed MCP server URL (remote-mcp-server-authless.<your-account>.workers.dev/sse)
- You can now use your MCP tools directly from the playground!
