# Add an MCP server for Arc users

# Add an MCP server for Arc users {#ariaid-title1}

Release version: Brazil  
Updated October 27, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Make a remote MCP server available to Arc users, so they can connect to it in one step without entering its details themselves.

## Before you begin

Role required: sn_app_arc.admin

Have the MCP server's URL and the client ID Arc uses to authenticate with it. If the server uses the Client Credentials grant type, also have its client secret and token URL.

## About this task

MCP servers you add appear first in the Available list in users' MCP Servers settings in Arc, ready to connect. Users can't edit or delete them.

## Procedure

1. In the navigation filter, enter <kbd class="ph userinput">sn_app_cowork_connector.list</kbd>, and press Enter.  
   The Arc Connectors list opens.
2. Select New.
3. Enter a Connector ID and a Display Label, and optionally a Description.
4. In the Connector Type field, select MCP Server.
5. In the MCP Server URL field, enter the server's URL.
6. In the Grant Type field, select how Arc authenticates with the server, and then complete the fields for that grant type.
   * None: Enter the Client ID, and optionally the Scopes.
   * Authorization Code (PKCE): Enter the Client ID, and optionally the Scopes.
   * Client Credentials: Enter the Client ID, Client Secret, and Token URL, and optionally the Scopes and Authorization URL.

## What to do next

To stop users from using the server, open its record and clear Active. For more information about what users see, see [Connect ServiceNow Arc to MCP servers](https://www.servicenow.com/docs/x3CU2FFKlmxFDu2TP0PHyg "Connect MCP servers so Arc can use tools and data from other services, such as GitHub, Sentry, SerpApi, and Postman. Each server you connect adds capabilities to the agent, and you control which servers each sub-agent can use.").
