Delete a specific test run (Data Center only — not supported on Cloud v2)
AI agents call delete_test_run to permanently remove resources in Zephyr Scale MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of test runs cannot be undone and results in permanent loss of test execution records and associated data. This is an irreversible destructive action that ranks higher than Write or Execute operations.
From the tool's definition Tool name is 'delete_test_run' and description states 'Delete a specific test run'. The word 'Delete' indicates irreversible removal of data.
Attacks that exploit this kind of access
Delete a specific test run (Data Center only — not supported on Cloud v2). It is categorised as a Destructive tool in the Zephyr Scale MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Zephyr Scale MCP Server MCP server in PolicyLayer and add a rule for delete_test_run: 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 Zephyr Scale MCP Server. Nothing to install.
delete_test_run 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_test_run 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_test_run. 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_test_run is provided by the Zephyr Scale MCP Server MCP server (milo0821/zephyr_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
