THE RISK

Why amm-delete needs a policy

Deleting an AMM from the XRP Ledger is a destructive operation that permanently removes a financial instrument and its associated state. This action cannot be reversed and represents a loss of the AMM resource. While not directly moving funds (Financial), it irreversibly destroys data/objects on the ledger, making Destructive the appropriate category.

From the tool's definition Tool name contains 'delete' and description states 'Delete an Automated Market Maker (AMM) from the XRP Ledger' — this is an irreversible removal of a ledger object that cannot be undone.

POLICY

How to control amm-delete

PolicyLayer is an MCP gateway — it sits between your AI agents and Xrpl mcp, and nothing reaches the server without passing your rules. This is the rule we recommend for amm-delete:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "amm-delete"
  ]
}

amm-delete disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Xrpl mcp — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
