# MCP Protocol (Model Context Protocol)

> Learn about the Model Context Protocol for tool integration

The Model Context Protocol (MCP) provides a standardized way for agents to interact with tools and external resources in the Corti Agentic Framework.

## What is MCP?

The Model Context Protocol (MCP) is a standardized protocol for exposing tools and resources to AI agents.

## When to Use MCP

MCP is ideal when you need to expose tools, APIs, or data sources to agents in a standardized way.

## How MCP Complements A2A

While A2A handles agent-to-agent communication, MCP handles agent-to-tool interactions, creating a complete communication framework.

## MCP in the Agentic Ecosystem

MCP plays a crucial role in the agentic ecosystem by enabling agents to interact with external systems and resources.

<Tip>
  MCP handles tool execution, while A2A handles agent-to-agent communication. See [A2A Protocol](/agentic/a2a-protocol) for more on inter-agent communication. For information about authenticating MCP server calls, see [MCP Authentication](/agentic/mcp-authentication).
