THE RISK

Medium Risk

Why record_artifact_events needs a policy

The tool 'records' events, which implies writing/creating data (event log entries) in a persistent store. Recording is a write operation. Severity is medium as misuse could pollute audit/cache logs. Confidence is moderate because the description is sparse and the tool appears on an eToro MCP server but seems more related to deployment/artifact infrastructure than eToro's trading API.

POLICY

How to control record_artifact_events

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 record_artifact_events:

policy.json

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

record_artifact_events 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.
