Deploy remote MCP servers on Cloudflare Workers with TypeScript, OAuth, and Durable Objects.

• Supports SSE and HTTP Streamable transports with automatic WebSocket hibernation for stateful sessions; choose from five auth templates (no-auth, bearer, GitHub/Google OAuth, enterprise SSO)
• Base path configuration is critical—server and client URLs must match exactly (e.g., serveSSE("/sse") requires client URL https://worker.dev/sse, not https://worker.dev)
• Includes 24 documented error solutions covering path mismatches, transport confusion, OAuth redirect URIs, CORS preflight, environment validation, and Durable Objects migrations
• Conditional tool registration enables role-based access control and feature flags; stateful tools persist across hibernation using this.state.storage instead of instance properties
