Why bulk_update_patient_metadata needs a policy

The tool name contains 'update' (Write action) and 'bulk' (affecting multiple records), suggesting reversible modification of healthcare data. Given patient metadata involvement, the impact could be significant if misused. Without a description, confidence is reduced. The tool does not appear to be Delete/Destructive, Financial, or Execute.

From the tool's definition Tool name 'bulk_update_patient_metadata' indicates batch modification of patient data. The empty description prevents full assessment of scope and constraints.

POLICY

How to control bulk_update_patient_metadata

PolicyLayer is an MCP gateway — it sits between your AI agents and Awslabs Amazon Sns Sqs, 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.
