Archive a policy group. Only non-live groups can be deleted. This is irreversible.
AI agents call lexq_groups_delete to permanently remove resources in LexQ — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently and irreversibly removes policy groups from the system. Even though it only applies to non-live groups (mitigating factors), the irreversible deletion operation categorizes it as Destructive rather than Write. The high severity reflects that losing policy group configurations could impact business rule management, though the blast radius is somewhat contained by the non-live restriction.
From the tool's definition Tool name contains 'delete'. Description explicitly states 'Archive a policy group' and 'This is irreversible.' The restriction to 'non-live groups' does not diminish the irreversible nature of the action.
Attacks that exploit this kind of access
Archive a policy group. Only non-live groups can be deleted. This is irreversible. It is categorised as a Destructive tool in the LexQ MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the LexQ MCP server in PolicyLayer and add a rule for lexq_groups_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 LexQ. Nothing to install.
lexq_groups_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 lexq_groups_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 lexq_groups_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.
lexq_groups_delete is provided by the LexQ MCP server (lexq-io/lexq-cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
