Why update_edge_config_items needs a policy

The tool modifies configuration state (edge config items) in a reversible manner. There is no indication of deletion, financial impact, or code execution. However, edge configuration changes can have moderate blast radius if misconfigured, affecting service delivery or security posture. Without full API documentation, confidence is moderate rather than high.

From the tool's definition Tool name 'update_edge_config_items' indicates modification of configuration settings. The verb 'update' denotes reversible data change. Description 'Update Edge Config Items' is minimal but consistent with a Write operation.

How to control update_edge_config_items

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 update_edge_config_items:

policy.json

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

update_edge_config_items 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.
