Model Context Protocol (MCP)

MCP standardizes how AI models interact with external data sources and tools.

The Architecture

• MCP Host: The application running the AI (e.g., Claude Desktop, Cursor).
• MCP Client: Connects the host to servers.
• MCP Server: Exposes local tools, files, or APIs to the client securely.

Capabilities

1. Resources: Read-only data (files, API responses).
2. Tools: Executable functions (run scripts, hit APIs).
3. Prompts: Reusable prompt templates.

MCP allows developers to write a tool once and use it across any compatible AI assistant.
