[Resources] Delete a resource by type and ID.
AI agents call resources_delete to permanently remove resources in CyPerf MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The 'delete' action is irreversible and permanently removes a resource. In the context of a network performance and security testing platform (CyPerf), deleting a resource could remove test configurations, results, agent definitions, or other critical infrastructure components that cannot be recovered.
From the tool's definition Tool name contains 'delete' and description states 'Delete a resource by type and ID.' This is an irreversible operation that removes data.
Attacks that exploit this kind of access
[Resources] Delete a resource by type and ID. It is categorised as a Destructive tool in the CyPerf MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the CyPerf MCP Server MCP server in PolicyLayer and add a rule for resources_delete: 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 CyPerf MCP Server. Nothing to install.
resources_delete 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 resources_delete 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 resources_delete. 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.
resources_delete is provided by the CyPerf MCP Server MCP server (keysight/cyperf-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
