THE RISK

Medium Risk

Why bulk_update_patient_metadata needs a policy

The tool performs updates to patient metadata in bulk, which is a Write operation (creates or modifies data reversibly). Severity is medium because bulk updates to healthcare metadata could affect multiple records and potentially impact patient care workflows, though the reversibility of updates keeps it below high severity.

From the tool's definition Tool name 'bulk_update_patient_metadata' indicates batch modification of patient data. Description is empty, limiting evidence quality.

POLICY

How to control bulk_update_patient_metadata

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

policy.json

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

bulk_update_patient_metadata 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.
