Excerpt

MCP Server Building Skill

You now have expertise in building MCP (Model Context Protocol) servers. MCP enables Claude to interact with external services through a standardized protocol.

MCP servers expose:

Tools: Functions Claude can call (like API endpoints)
Resources: Data Claude can read (like files or database records)
Prompts: Pre-built prompt templates

Quick Start: Python MCP Server

1. Project Setup

# Create project
mkdir my-mcp-server && cd my-mcp-server
python3 -m venv venv && source venv/bin/activate

# Install MCP SDK
pip install mcp

2. Basic Server Template
