Reference information for ServiceNow Arc, including environment and capability controls, sandbox file protection, local MCP server management, and policy change testing.
* **[Turn off local MCP servers](https://www.servicenow.com/docs/sNC8x9tbc~9kgayttN8tCw)**   
  Turn off local MCP servers for users or user groups so that Arc can't run MCP server actions directly on user devices.
* **[Prevent changes to sandbox files](https://www.servicenow.com/docs/jMTnCdQySAZ1aXHEaUVMxw)**   
  Add a filesystem deny rule to your sandbox policy so that agent actions can't modify files in the sandbox runtime directory on user devices.
* **[Environment and capability controls](https://www.servicenow.com/docs/8j33P1irKGmWN7SsCfzabQ)**   
  Environment and capability controls limit what ServiceNow Arc can access while an action runs, keeping the agent within the boundaries you set.
* **[Test a ServiceNow Arc policy change](https://www.servicenow.com/docs/5lVBTg8gVKRfD__Y~R4w8g)**   
  Verify that a policy change works as intended before you apply it to all users.
