What is FastMCP and how does it work?

FastMCP is a server for Model Context Protocol tools, turning Python functions into typed, async AI-callable endpoints with Pydantic validation.

How do I migrate legacy Python scraping scripts to FastMCP?

Refactor inputs to explicit types (e.g., lat/lon floats), outputs to BaseModels, wrap in @mcp.tool(), and use stable APIs over DOM parsing.

Will FastMCP make my AI agents more reliable in production?

Yes — typed payloads cut ambiguity, clear errors enable retries, and boundaries shrink attack surfaces, perfect for enterprise scale.
