# Configure an AI agent as an MCP tool

Enable an AI agent to be discoverable and accessible as an MCP tool by configuring authentication, communication mode, and third-party access settings.

## Before you begin

You must have access to AI Agent Studio and permission to configure authentication settings.

Role required: admin

## Procedure

1.  Make sure the ITSM MCP Server is activated.

    For information on activating the ITSM MCP Server, see [Activate the ITSM MCP Server](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/it-service-management/set-up-itsm-mcp-server.md).

2.  Authenticate the ITSM MCP Server with your ServiceNow instance.

    -   See the [Connecting to an MCP server from an MCP client](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/intelligent-experiences/connect-mcp-server-client.md) to set up the OAuth and connect to the ITSM MCP Server.
    -   In the authentication scope field, select **a2aauthscope**. This enables the REST A2A protocol to access your AI agent MCP tools.
3.  Configure the communication mode for external AI agents in AI Agent Studio.

    1.  Navigate to **AI Agent Studio** > **Settings**.

    2.  In the left panel, select **Discoverability**.

    3.  Enable the communication mode options and set the communication mode to **Synchronous**.

    For more information on the communication modes, see [Integrate external AI agents](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/intelligent-experiences/integrate-external-aia.md).

4.  Enable third-party access on the AI agent definition.

    In AI Agent Studio, open the AI agent and navigate to the **Define the specialty** screen. Enable the toggle for **Allow third party access to this AI agent**.

    **Note:** To make modifications to the record such as allowing third party to access the AI agent, see [Duplicate an AI agent](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/intelligent-experiences/clone-ai-agent.md). You must also update the agent sys\_id in the corresponding tool input of the MCP tool.

## What to do next

After completing these steps, the AI agent is discoverable as an MCP tool and can be used by external systems and workflows.
