FastMCP is a specialized TypeScript framework that simplifies the process of building servers for the Model Context Protocol (MCP), allowing AI agents to interact with external tools.

Which schema libraries does FastMCP support?

FastMCP is flexible and supports popular validation libraries like Zod, ArkType, and Valibot for defining tool parameters and ensuring type safety.

Can I use FastMCP for serverless deployments?

Yes, FastMCP supports a stateless mode specifically designed for serverless environments, making it ideal for scalable cloud deployments.

Does this skill support multi-modal outputs?

Yes, it includes comprehensive patterns for returning various content types including text, images, and audio content through MCP tools.

What transport types are available in FastMCP?

You can configure your servers to use stdio, HTTP streaming, or SSE (Server-Sent Events) transports depending on your infrastructure needs.
