MCP Server Builder

What this skill does

This skill walks you through building a Model Context Protocol (MCP) server from scratch. MCP servers expose tools, resources, and prompts to AI agents (Claude, Cursor, Cline, etc.). This skill covers both Python (FastMCP) and TypeScript (official SDK) implementations, with production-ready patterns for error handling, input validation, and tool description writing.
