What is dual-protocol support in mcp-use?

It implements the SEP-1865 standard, allowing the same widget code to work natively in MCP clients like Claude and via Skybridge in ChatGPT.

What is the fastest way to start a new MCP project?

Use the command 'npx create-mcp-use-app my-server' to bootstrap a new project with templates for full-featured, ChatGPT-optimized, or minimal implementations.

How does automatic widget registration work?

The server scans the 'resources/' folder for .tsx files or widget.tsx entry points, automatically extracting metadata and registering them as both MCP Tools and Resources.

How do I deploy my MCP server?

You can deploy directly to mcp-use Cloud using the 'yarn deploy' command after logging in with 'npx mcp-use login' for auto-scaled hosting.

Can I test my MCP server with ChatGPT before deploying?

Yes, you can use the built-in tunneling feature with 'mcp-use start --tunnel' to generate a public URL for testing with external clients like ChatGPT.
