WHAT IT DOES

What search_patients does on Nitrostack

AI agents call search_patients to retrieve information from Nitrostack without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why search_patients is rated Low

This tool retrieves patient information from a healthcare FHIR system. While the empty description reduces confidence slightly, the name 'search_patients' clearly indicates a read/query function.

From the tool's definition Tool name 'search_patients' indicates a query operation. The description is empty, so classification relies on the name and context. In healthcare systems, searching for patient records is a read operation that retrieves data without modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs search_patients safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Nitrostack, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For search_patients, this is the rule to start with:

search_patients Allowed

search_patients is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Nitrostack, apply this rule, and every search_patients call is checked against it from then on.
