SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires anthropic, mcp, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides a comprehensive guide and resources for developing high-quality MCP (Model Context Protocol) servers, enabling Large Language Models (LLMs) to interact with external services through well-designed tools.

Core Features & Use Cases

  • MCP Server Development: Learn best practices for creating MCP servers in Python (FastMCP) or Node/TypeScript (MCP SDK).
  • Tool Design & Implementation: Understand how to define input/output schemas, write clear descriptions, and implement tools effectively.
  • Evaluation Framework: Create robust evaluations to test the LLM's ability to use your MCP server for complex, real-world tasks.
  • Use Case: You need to build an MCP server that allows an LLM to manage GitHub issues. This Skill guides you through setting up the server, implementing tools for creating, listing, and updating issues, and testing its effectiveness.

Quick Start

Follow the steps in the SKILL.md file to set up your MCP server project.

FAQPage Schema
How do I build an MCP server for LLM integration?▼

To build an MCP server for LLM integration, use Python with FastMCP or Node/TypeScript with the MCP SDK. Define input/output schemas, write clear descriptions, and implement tools to connect LLMs with external services.

How do I design tools for an MCP server?▼

Design MCP server tools by defining structured input and output schemas, writing clear descriptions, and implementing tools effectively to allow LLMs to interact with external services.

Can I use Python and FastMCP to create an MCP server?▼

Yes, you can create an MCP server using Python with the FastMCP framework. This Skill guides development in Python alongside Node/TypeScript options using the MCP SDK.

How do I evaluate an LLM's ability to use my MCP server?▼

Evaluate an LLM's ability to use your MCP server by creating robust evaluations to test complex, real-world tasks using provided evaluation frameworks and strategies.

What is the best way to connect an LLM to external services?▼

The best way to connect an LLM to external services is by building a Model Context Protocol server. This provides well-designed tools that enable LLMs to interact with external APIs.

Do I need the TypeScript SDK to build an MCP server?▼

No, you do not need the TypeScript SDK specifically. You can build MCP servers using either Node/TypeScript with the MCP SDK or Python with FastMCP.
