Model Context Protocol (MCP) is an open protocol developed by Anthropic that enables AI assistants like Claude to securely interact with external tools, data sources, and services. Think of it as a standardized way for AI models to:

• Access tools: Execute functions like searching databases, calling APIs, or running calculations
• Read resources: Fetch data from files, databases, or external services
• Use prompts: Leverage pre-built prompt templates for common tasks

Here are some practical MCP servers you might build:

1. Weather Server: Provides current weather data for any city
2. Database Server: Allows querying a PostgreSQL/MySQL database
3. File System Server: Enables reading/writing files on disk
4. API Integration Server: Connects to third-party APIs (GitHub, Slack, etc.)
5. Calculator Server: Performs complex mathematical operations
