# Custom MCP Servers

> Connect custom Model Context Protocol servers to Sontairo

The Model Context Protocol (MCP) allows you to connect custom tool servers to Sontairo, extending agent capabilities beyond built-in integrations.

## What is MCP?

MCP is an open standard for connecting AI agents to external tools. An MCP server exposes a set of tools (functions) that agents can call during task execution.

## Adding an MCP Connector

1. Go to **Connectors** → **Add Connector**
2. Search for "MCP" or select the MCP category
3. Name the connector and create it
4. Configure the MCP server URL in the connector settings

## Building an MCP Server

An MCP server is an HTTP endpoint that implements the MCP protocol. It must respond to tool discovery and tool execution requests.

Refer to the [MCP specification](https://modelcontextprotocol.io/) for implementation details.

<Tip>
  MCP servers are ideal for connecting internal tools, databases, or custom APIs that your agents need to access.
