AI agents call delete_macpool_block to permanently remove resources in Intersight MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes MAC pool blocks, which is an irreversible destructive action on infrastructure configuration. While not directly dangerous to data availability, deleting MAC pools can break network provisioning and server assignments if dependent systems rely on those MAC addresses.
From the tool's definition Tool name 'delete_macpool_block' and description 'Delete a MAC pool block' explicitly indicate irreversible deletion of MAC address pool resources.
Documented attack patterns abuse exactly the kind of access delete_macpool_block gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Intersight MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_macpool_block:
{
"version": "1",
"default": "deny",
"hide": [
"delete_macpool_block"
]
}delete_macpool_block disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a MAC pool block. It is categorised as a Destructive tool in the Intersight MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Intersight MCP Server MCP server in PolicyLayer and add a rule for delete_macpool_block: 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 Intersight MCP Server. Nothing to install.
delete_macpool_block 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 delete_macpool_block 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 delete_macpool_block. 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.
delete_macpool_block is provided by the Intersight MCP Server MCP server (jim-coyne/intersight_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Intersight MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
