FAQPage Schema
How do I build an MCP server with TypeScript and Python?▼

To build an MCP server, you use the MCP SDK for Node/TypeScript or FastMCP for Python. This skill scaffolds the server, enforces structured input validation with Zod or Pydantic, and registers tools with explicit schemas.

What is the best way to register tools in a Model Context Protocol server?▼

The best way to register tools in an MCP server is by defining explicit tool schemas with structured input validation. This skill provides patterns for Python and TypeScript to ensure reliable, maintainable tool registration.

Does the MCP SDK support Pydantic and Zod for input validation?▼

Yes, MCP server implementations support structured input validation. This skill enforces Pydantic for Python (FastMCP) and Zod for Node/TypeScript to ensure explicit tool schemas and robust error handling.

Can I use FastMCP to scaffold an enterprise automation assistant?▼

Yes, you can use FastMCP to scaffold an enterprise automation assistant. This skill helps you build a complete MCP server with validated inputs, clear tool schemas, and established testing patterns for reliable infrastructure.

What testing patterns should I follow for Model Context Protocol server development?▼

For MCP server development, you should follow testing patterns that ensure reliability and maintainability. This skill provides guidance on core infrastructure setup, tool registration validation, and security best practices.

Why does my MCP server need explicit tool schemas and error handling?▼

Your MCP server needs explicit tool schemas and error handling to align with Model Context Protocol specifications. This skill enforces structured validation and security best practices to prevent runtime errors and ensure robust performance.
