# MCP Servers

> Configure Model Context Protocol servers for extended capabilities.

MCP (Model Context Protocol) servers extend Dify's capabilities by providing standardized interfaces to external systems.

## What is MCP?

The Model Context Protocol is an open standard for connecting AI models to external tools and data sources. MCP servers expose capabilities that agents can use during conversations.
