# MCP

{% hint style="warning" %}
MCP features are advanced features. Make sure you're comfortable building workflows in Relay.app first.
{% endhint %}

Relay.app lets you connect with other AI tools through the [Model Context Protocol](https://modelcontextprotocol.io/overview) (MCP) in three ways:

1. **You can create MCP Servers in Relay.app to use in other AI products (like Claude and Cursor)**\
   \&#xNAN;*This is a great way to enable these products to perform specific actions in apps you've connected in Relay.app, like your CRM, Bug Tracker or Task list.*
2. **Connect Agent steps in Relay.app with remote MCP servers**\
   \&#xNAN;*Note: currently only Agents using Anthropic Claude models can connect to remote MCP servers*
3. **Call specific tools MCP in remote MCP servers from within your Relay.app workflows**

### **1. Creating MCP Servers in Relay.app**

To create an MCP Server in Relay.app, click 'MCP Server' in the Trigger menu. This will replace the current workflow with the MCP Server configuration interface.

#### Example MCP server in Relay.app

The MCP server below exposes 1 tool: '**Create Task in Asana**'. The tool has 1 action inside it, to create a task in Asana.

### 2. Connect Agent steps in Relay.app with a remote MCP server

To connect your AI Agent steps in Relay.app with a remote MCP server, click '+Tool' and add a new MCP server from the 'Remote MCP' submenu.

Note: this currently only works when using Anthropic Claude models.

### 3. Call a specific remote MCP tool within your workflow

Inside the 'AI' menu, you'll find a 'Call MCP tool' step that lets you invoke a specific tool from a connected remote MCP server as part of the workflow.
