Invalidate a claim link so it can no longer be used. Does not remove access from a user who already claimed the goal. Use this if a link was sent to the wrong person or needs to be regenerated.
AI agents call revoke_claim to permanently remove resources in Unfold It MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Revoking a claim link is an irreversible invalidation — the link can no longer be used once revoked. While it doesn't remove access from users who already claimed the goal, it permanently destroys the usability of the link itself. This aligns with Destructive (irreversible action), though the blast radius is medium since it only affects future claimants, not existing access.

Attacks that exploit this kind of access
Invalidate a claim link so it can no longer be used. Does not remove access from a user who already claimed the goal. Use this if a link was sent to the wrong person or needs to be regenerated. It is categorised as a Destructive tool in the Unfold It MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Unfold It MCP Server MCP server in PolicyLayer and add a rule for revoke_claim: 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 Unfold It MCP Server. Nothing to install.
revoke_claim 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 revoke_claim 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 revoke_claim. 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.
revoke_claim is provided by the Unfold It MCP Server MCP server (unfold-it/unfoldit-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
