THE RISK

Medium Risk

Why create_access_group_project needs a policy

This tool creates a new access group project, which is a reversible modification to system state. It does not execute arbitrary code, delete data, or move money. The blast radius is medium because misconfiguration of access groups could grant unintended permissions, but the operation itself is not destructive and can be remediated.

From the tool's definition Tool name 'create_access_group_project' and description 'Create an access group project' indicate creation of a new resource.

POLICY

How to control create_access_group_project

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 create_access_group_project:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_access_group_project": {
      "limits": [
        {
          "counter": "create_access_group_project_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_access_group_project stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
