Why delegate-list needs a policy

This tool retrieves delegate permissions for an account, which is a read-only operation with no side effects. It queries ledger data to display current delegation state. While the sibling tools include financial operations (batch-payment, approve-token-spending) and destructive operations (amm-delete), this specific tool only lists information.

From the tool's definition Tool name 'delegate-list' and description 'List all delegate permissions for an account' indicate a query operation that retrieves and returns existing delegation information without modifying state.

POLICY

How to control delegate-list

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 delegate-list:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "delegate-list": {}
  }
}

delegate-list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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.

Questions about delegate-list

What does the delegate-list tool do? +

List all delegate permissions for an account. It is categorised as a Read tool in the Xrpl mcp MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on delegate-list? +

Register the Xrpl MCP server in PolicyLayer and add a rule for delegate-list: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Xrpl mcp. Nothing to install.

What risk level is delegate-list? +

Can I rate-limit delegate-list? +

Yes. Add a rate_limit block to the delegate-list rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block delegate-list completely? +

What MCP server provides delegate-list? +

delegate-list is provided by the Xrpl MCP server (romthpt/mcp-xrpl). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Xrpl mcp tool call.

Start from Xrpl mcp, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
