Why credential-get-info needs a policy

This tool queries and retrieves credential information from the ledger. It performs no writes, executions, deletions, or financial transactions. The 'get' verb and 'information' retrieval purpose clearly indicate a read-only operation with minimal blast radius if misused by an AI agent.

From the tool's definition Tool name 'credential-get-info' and description 'Get information about a specific credential on the XRP Ledger' indicate a retrieval operation with no modification or state-changing effects.

POLICY

How to control credential-get-info

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 credential-get-info:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "credential-get-info": {}
  }
}

credential-get-info 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.
