Delete a VRF
AI agents call delete_vrf to permanently remove resources in ACI 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 a VRF from the ACI fabric, which cannot be undone. VRFs are critical network infrastructure components that segment routing domains and carry production traffic. Deletion destroys the routing context and will cause immediate network disruption for any applications or endpoints using that VRF. This is an irreversible destructive action with high blast radius in production environments.
From the tool's definition Tool named 'delete_vrf' with description 'Delete a VRF'. The verb 'delete' combined with VRF (Virtual Routing and Forwarding) resource indicates irreversible removal of network routing configuration.
Attacks that exploit this kind of access
Delete a VRF. It is categorised as a Destructive tool in the ACI MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the ACI MCP Server MCP server in PolicyLayer and add a rule for delete_vrf: 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 ACI MCP Server. Nothing to install.
delete_vrf 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_vrf 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_vrf. 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_vrf is provided by the ACI MCP Server MCP server (jim-coyne/aci_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
