WHAT IT DOES

What offer-cancel does on Xrpl mcp

AI agents call offer-cancel to permanently remove resources in Xrpl mcp, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why offer-cancel is rated Critical

Cancelling an offer permanently removes it from the XRP Ledger order book. This action is irreversible — once the offer is cancelled, it cannot be restored. Given that offers may represent pending financial trades or liquidity positions, irreversible deletion of an on-chain object warrants Destructive classification with high severity.

RECOMMENDED RULE

The rule that runs offer-cancel safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Xrpl mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For offer-cancel, this is the rule to start with:

offer-cancel Hidden

offer-cancel is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
