Why list_access_group_projects needs a policy

This tool queries and returns a list of projects associated with an access group—a read-only operation with no side effects. It retrieves information without altering state, executing code, or triggering external actions. The blast radius of misuse is minimal: an unauthorized listing of projects could expose metadata but cannot modify or delete resources, nor trigger financial transactions.

From the tool's definition Tool name 'list_access_group_projects' and description 'List projects of an access group' indicate retrieval/enumeration of existing data with no modification, creation, deletion, or external execution.

POLICY

How to control list_access_group_projects

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 list_access_group_projects:

policy.json

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

list_access_group_projects 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.
