Activate or deactivate a tool
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
-
Open the MCP server record: navigate to Settings > AI Gateway, and on the Overview tab, select the server name, or in AI Control Tower, navigate to Inventory > Assets > MCP servers and select the server name.
-
Select the AI Gateway tab, and then select the Tools sub-tab.
-
Select Refresh tools.
If the server's authorization has expired, select Reauthorize first.
-
Review the tool's Scan status and Threat category.
-
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.
