Why domain_registry needs a policy

This tool retrieves domain transfer information without creating, modifying, deleting, or executing operations. It falls squarely into the Read category as it queries data about domain transfers.

From the tool's definition Tool name 'domain_registry' with description 'Get domain transfer info' indicates a retrieval/query operation. The verb 'Get' and the focus on fetching information (domain transfer details) without modification suggests read-only access.

POLICY

How to control domain_registry

PolicyLayer is an MCP gateway — it sits between your AI agents and eToro MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for domain_registry:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "domain_registry": {}
  }
}

domain_registry 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 eToro MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
