WHAT IT DOES

What amm-create does on Xrpl mcp

AI agents use amm-create 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 amm-create is rated Critical

Creating an AMM involves committing financial assets (tokens/XRP) to a liquidity pool on a blockchain, which constitutes a financial obligation. This action deploys real funds into a decentralized market-making contract on the XRP Ledger, making it a Financial category action with critical severity due to the potential for irreversible loss of funds if misconfigured.

RECOMMENDED RULE

The rule that runs amm-create safely

amm-create Approval-gated

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