Cancel an active refinement session and clean up worktrees.
AI agents call finslipa_cancel to permanently remove resources in Finsliparn — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cancelling a session and cleaning up worktrees destroys the in-progress refinement state and associated filesystem worktrees. This is not easily reversible — any uncommitted work or session state would be lost. The most severe applicable category is Destructive.
From the tool's definition 'Cancel an active refinement session and clean up worktrees' — cancellation of a session and cleanup of worktrees implies irreversible removal of working state and temporary workspace data.
Attacks that exploit this kind of access
Cancel an active refinement session and clean up worktrees. It is categorised as a Destructive tool in the Finsliparn MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Finsliparn MCP server in PolicyLayer and add a rule for finslipa_cancel: 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 Finsliparn. Nothing to install.
finslipa_cancel 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 finslipa_cancel 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 finslipa_cancel. 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.
finslipa_cancel is provided by the Finsliparn MCP server (jgabor/finsliparn). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
