Activate the ServiceNow Arc plugin, and then download, install, and set up Arc.
* **[Activate the ServiceNow Arc plugin](https://www.servicenow.com/docs/kySG1DWuk3gkC2sJMQJXaQ)**   
  You can activate the ServiceNow Arc plugin (sn_app_cowork) for ServiceNow Arc if you have the admin role. The application includes demo data and installs related ServiceNow® Store applications and plugins if they aren't already installed.
* **[Download and install ServiceNow Arc for macOS](https://www.servicenow.com/docs/5q3VwRAgbkEDGh5MFWeMiA)**   
  Install ServiceNow Arc on a Mac with an M-series processor to use the AI desktop agent on your computer.
* **[Download and install Arc on Windows](https://www.servicenow.com/docs/lmiE6aopcHUUg6fiU8YfNw)**   
  Install ServiceNow Arc on your Windows computer.
* **[Set up ServiceNow Arc](https://www.servicenow.com/docs/bdVeuIBltnVAdR~lZ2vo1g)**   
  Connect Arc to your ServiceNow instance and prepare your workspace and secure sandbox.
* **[Create a ServiceNow Arc agent policy](https://www.servicenow.com/docs/e8cJgEs0xIwIy0M6LLsBOg)**   
  Create a policy to define what ServiceNow Arc can do, which actions need human approval, and which actions are blocked.
* **[Configure a ServiceNow Arc agent policy](https://www.servicenow.com/docs/Y1pTo6E5rwRFrWyW17~LIg)**   
  Add tool gates, approval patterns, network rules, sandbox rules, capability overrides, connector scopes, and file type rules to a policy to control what Arc can do for the users the policy applies to.
* **[Manage Arc agent policies in AI Control Tower](https://www.servicenow.com/docs/c7IVasEHoEUya3OETLq9tw)**   
  Create and manage Arc agent policies and their rules in AI Control Tower, so you govern Arc in the same place as the rest of your AI systems.
* **[Make auto mode available to Arc users](https://www.servicenow.com/docs/jTfXRbkdvXavgJfX~Q36Pg)**   
  Turn on auto mode for the users a policy covers and choose which tools can use it, so users can let an AI model reviewer approve lower risk actions instead of answering every prompt.
* **[Add an MCP server for Arc users](https://www.servicenow.com/docs/jZfmkWr0M2NLsG4i7skagw)**   
  Make a remote MCP server available to Arc users, so they can connect to it in one step without entering its details themselves.
* **[Trace evaluation for Arc in AI Control Tower](https://www.servicenow.com/docs/4aIAW2O07mePpT4~04HXZw)**   
  AI Control Tower scores the traces that Arc sends for quality and safety. Review the scores to understand usage patterns and identify where responses fall short.
