[Results] Delete one or more test results.
AI agents call results_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.
This tool permanently removes test result data without the ability to undo the operation. Deletion is irreversible and represents data loss. While not as critical as deleting production infrastructure or financial records, the loss of historical test data (especially in a security/performance testing context) has significant operational impact.
From the tool's definition Tool name 'results_delete' and description 'Delete one or more test results' indicate irreversible deletion of data. The verb 'delete' and plural 'results' confirm the destructive nature—test results cannot be recovered once removed.
Attacks that exploit this kind of access
[Results] Delete one or more test results. 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 results_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.
results_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 results_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 results_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.
results_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.
