MCP Documentation

What is MCP?

The Model Context Protocol (MCP) is an open standard that enables developers to build secure, bidirectional connectors between their data sources and AI-assisted tools.

Basic Architecture

MCP follows a Client-Host-Server architecture based on JSON-RPC 2.0:

• MCP Host: The AI application (e.g. Claude Desktop, IDEs).
• MCP Client: Maintains a 1:1 connection with the server.
• MCP Server: Exposes resources, prompts and tools through the protocol.
