SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill guides developers in building high-quality MCP (Model Context Protocol) servers that enable LLMs to safely interact with external services using well-designed tools. It covers both Python (FastMCP) and Node/TypeScript (MCP SDK) implementations.

Core Features & Use Cases

  • Structured tool design: Learn to design modular, reusable MCP tools with clear input/output schemas.
  • Platform-agnostic guidance: Apply MCP patterns across Python and TypeScript SDKs.
  • Practical workflows: Scaffold server skeletons, tool registrations, and error handling to accelerate MVP-to-production migrations.

Quick Start

Use this skill to scaffold an MCP server for a new external API integration, then register a couple of example tools.

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

Building an MCP server involves using the TypeScript MCP SDK or Python FastMCP to design modular tools with clear input/output schemas, handle errors, and register tools for LLM interaction.

What is the best way to design tools for an MCP server?

The best way to design MCP server tools is to create modular, reusable components with clear input and output schemas, ensuring maintainable architecture and safe LLM interaction with external services.

Does MCP server guidance support both Python and TypeScript SDKs?

Yes, MCP server guidance supports both Python FastMCP and Node/TypeScript MCP SDK implementations, providing platform-agnostic patterns for building production-grade servers across different environments.

How do I handle errors when registering tools in an MCP server?

You handle errors during MCP server tool registration by implementing proper error handling mechanisms provided in the SDK guidance, ensuring robust operation when LLMs interact with external services.

When do I need to use resources like scripts and references in an MCP server?

You use optional resources such as scripts and references in an MCP server when you need to support production-grade server operations and provide additional context for external service interactions.
