Delete a link by ID.
AI agents call delete_link 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.
The tool performs an irreversible deletion operation. In the context of a test management system, deleting links between test cases and Jira issues or between test artifacts removes associations that users may rely on for traceability and test coverage tracking.
From the tool's definition Tool name 'delete_link' combined with description 'Delete a link by ID' indicates irreversible deletion of data. The action cannot be undone once executed.
Attacks that exploit this kind of access
Delete a link by ID. 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_link: 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_link 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_link 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_link. 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_link is provided by the Zephyr Scale MCP Server MCP server (metquay/zephyr-scale-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
