Frequently Asked Questions

FAQPage Schema
How to install FastMCP?▼

Run `npx skills add jlowin/fastmcp --all -g -y` in your terminal to install all skills in this suite globally.

What is FastMCP used for?▼

FastMCP is a Python framework for building MCP servers, clients, and interactive apps. It turns plain Python functions into tools that AI models can discover and call.

How do I call tools on an MCP server from the command line?▼

Use `fastmcp list` to see what tools a server offers and `fastmcp call` to invoke them with simple key=value arguments. It works with URLs, local Python files, and servers already configured in your editor.

Does FastMCP work with Claude Code and Cursor?▼

Yes. FastMCP servers follow the open Model Context Protocol standard, so they connect to Claude Code, Claude Desktop, Cursor, Gemini CLI, and other MCP-compatible tools.

Do I need to know the MCP protocol to use FastMCP?▼

No. You write ordinary Python functions with a decorator, and FastMCP generates the schemas, validation, and protocol handling for you automatically.
