Unmap a memory region.
AI agents call unmap_memory to permanently remove resources in MCPEmulate — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Unmapping a memory region destroys the contents of that region and cannot be undone without re-mapping and reloading data. This constitutes an irreversible destructive action within the emulator session.
From the tool's definition 'Unmap a memory region' — unmapping memory is an irreversible operation within the emulation session that permanently removes the mapped region, destroying any data held there.
Attacks that exploit this kind of access
Unmap a memory region. It is categorised as a Destructive tool in the MCPEmulate MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCPEmulate MCP server in PolicyLayer and add a rule for unmap_memory: 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 MCPEmulate. Nothing to install.
unmap_memory 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 unmap_memory 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 unmap_memory. 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.
unmap_memory is provided by the MCPEmulate MCP server (labguy94/mcpemulate). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
