Remove a device from the known/trusted list.
AI agents call remove_device_known to permanently remove resources in Network Scanner MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a device from the known/trusted list is an irreversible deletion of a trust relationship. Once removed, the device loses its trusted status, which could affect security policies, access controls, and monitoring behavior. This action cannot be passively undone without re-adding the device, making it Destructive.

Attacks that exploit this kind of access
Remove a device from the known/trusted list. It is categorised as a Destructive tool in the Network Scanner MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Network Scanner MCP server in PolicyLayer and add a rule for remove_device_known: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Network Scanner MCP. Nothing to install.
remove_device_known is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the remove_device_known rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for remove_device_known. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
remove_device_known is provided by the Network Scanner MCP server (marc-shade/network-scanner-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
