WHAT IT DOES

What check-cancel does on Xrpl mcp

AI agents call check-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 check-cancel is rated Critical

Cancelling a check is an irreversible on-ledger operation that permanently destroys the uncashed check object. Once cancelled, the check cannot be reinstated or cashed, making this a destructive action on the XRP Ledger.

RECOMMENDED RULE

The rule that runs check-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 check-cancel, this is the rule to start with:

check-cancel Hidden

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

The button opens the PolicyLayer dashboard: create your workspace, connect Xrpl mcp, apply this rule, and every check-cancel call is checked against it from then on.
