WHAT IT DOES

What payment does on Xrpl mcp

AI agents use payment to commit financial operations through Xrpl mcp, usually the final step of a payment, billing, or trading workflow. A call moves real money.

RISK

Why payment is rated Critical

This tool moves XRP or tokens between accounts on the XRP Ledger, which constitutes a direct financial transaction. Payments on a blockchain are irreversible, making misuse potentially catastrophic. The blast radius is critical as an AI agent could drain funds from an account.

RECOMMENDED RULE

The rule that runs payment 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 payment, this is the rule to start with:

payment Approval-gated

Any call to payment is blocked until a human approves it. The rest of the server keeps working.
