POLICY

How to control get_patient_studies

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_patient_studies": {}
  }
}

get_patient_studies is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
