SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill provides a comprehensive guide and resources for developing robust Model Context Protocol (MCP) servers, enabling Large Language Models (LLMs) to interact with external services through well-defined 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: Guidance on defining schemas, descriptions, and implementing tools for LLM interaction.
  • Evaluation Framework: Understand how to create evaluations to test the effectiveness of your MCP server.
  • 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, defining tools for creating, listing, and closing issues, and testing its performance.

Quick Start

Follow the Node/TypeScript guide to set up a new MCP server project.
