THE RISK

Why start_fhir_export_job needs a policy

This tool executes a job/operation rather than simply reading data. While it exports data (which might initially appear as a Read operation), the act of 'starting' a job is an Execute action that triggers AWS backend processing. The tool initiates an asynchronous operation whose side effects (data extraction, job resource consumption, potential logging/audit trail generation) cannot be immediately reversed.

From the tool's definition The tool name and description indicate 'Start a FHIR export job' which triggers an external operation (job execution) on AWS HealthLake.

POLICY

How to control start_fhir_export_job

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 start_fhir_export_job:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "start_fhir_export_job": {
      "limits": [
        {
          "counter": "start_fhir_export_job_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

start_fhir_export_job stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Awslabs Amazon Sns Sqs — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about start_fhir_export_job

What does the start_fhir_export_job tool do? +

Start a FHIR export job to export data from HealthLake. It is categorised as a Execute tool in the Awslabs Amazon Sns Sqs MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on start_fhir_export_job? +

Register the Awslabs Amazon Sns Sqs MCP server in PolicyLayer and add a rule for start_fhir_export_job: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Awslabs Amazon Sns Sqs. Nothing to install.

What risk level is start_fhir_export_job? +

start_fhir_export_job is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit start_fhir_export_job? +

Yes. Add a rate_limit block to the start_fhir_export_job rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block start_fhir_export_job completely? +

Set action: deny in the PolicyLayer policy for start_fhir_export_job. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides start_fhir_export_job? +

start_fhir_export_job is provided by the Awslabs Amazon Sns Sqs MCP server (awslabs.amazon-sns-sqs-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Awslabs Amazon Sns Sqs tool call.

Start from Awslabs Amazon Sns Sqs, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
