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 framework for developing high-quality MCP (Model Context Protocol) servers, enabling 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) and Node/TypeScript (MCP SDK).
  • Tool Implementation: Guidance on designing, naming, and implementing tools with robust input/output schemas.
  • Evaluation Framework: Understand how to create evaluations to test LLM effectiveness with 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, implementing tools like github_create_issue and github_list_issues, and testing its performance.

Quick Start

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