# Activate or deactivate a tool

# Activate or deactivate a tool {#ariaid-title1}

Release version: Brazil

Allow agents to call one MCP server tool through AI Gateway, or block every call to it.

## Before you begin

AI Gateway and the server's connection must be on. While either is paused, tools can't be changed.

Role required: sn_ai_governance.ai_steward

## Procedure

1. Open the MCP server record: navigate to SettingsAI Gateway, and on the Overview tab, select the server name, or in AI Control Tower, navigate to InventoryAssetsMCP servers and select the server name.
2. Select the AI Gateway tab, and then select the Tools sub-tab.
3. **Optional:** Select Refresh tools.  
   If the server's authorization has expired, select Reauthorize first.
4. Review the tool's Scan status and Threat category.
5. Turn the tool's Active toggle on or off, and then select Activate or Deactivate in the confirmation dialog.

## Result

AI Gateway is set up to block every call to a tool when it's inactive. When a tool is active, agents can call it, and any policies for the tool apply to each call. The tool's status also shows in the Available MCP tools panel on the record's Details tab.

## What to do next

If Automatically deactivate vulnerable tools is on, a later scan can change a tool's status. For details, see [AI Gateway Tools tab](https://www.servicenow.com/docs/KWN_bfjcj8Ia33B7sC5EmA "Use the Tools tab of the AI Gateway settings page to choose whether tools are automatically deactivated after a security scan or activated after approval.").
