Delete a test case
AI agents call delete_case to permanently remove resources in TestRail MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a test case permanently removes data that cannot be recovered without backup restoration. This is a destructive action that eliminates test artifacts, potentially impacting test coverage tracking, audit trails, and project history. While the blast radius is scoped to a single test case (not financial or systemic), the irreversible nature of deletion makes this Destructive rather than Write.
From the tool's definition Tool name is 'delete_case' and description states 'Delete a test case' — this is an irreversible deletion operation that removes test case data from TestRail.
Attacks that exploit this kind of access
Delete a test case. It is categorised as a Destructive tool in the TestRail MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the TestRail MCP Server MCP server in PolicyLayer and add a rule for delete_case: 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 TestRail MCP Server. Nothing to install.
delete_case 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_case 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_case. 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_case is provided by the TestRail MCP Server MCP server (tenbarrel6/testrail-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
delete_case is one line of TestRail MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
