What is MCP (Model Context Protocol)?
Definition
MCP (Model Context Protocol) is an open protocol developed by Anthropic that enables AI models to connect with external data sources, tools, and applications in a standardized way. Think of it as "USB for AI" - a universal connector that allows any AI model to plug into any data source or tool.
How MCP Works
The protocol establishes three main connection types:
- Resources: Structured data from your applications (files, databases, APIs)
- Tools: Functions the AI can call to perform actions (send emails, query databases, etc.)
- Prompts: Reusable templates that help the AI interact with specific features
Why MCP Matters
- Standardization: One protocol works across all AI models and data sources
- Security: Centralized permissions - you control what data AI can access
- Flexibility: Switch AI providers without re-engineering integrations
- Scalability: Connect to multiple data sources simultaneously
