Start a FHIR import job to load data into HealthLake
AI agents invoke start_fhir_import_job to trigger actions in Amazon SageMaker AI MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
Starting an import job is an Execute action because it triggers an autonomous process in an external system (AWS HealthLake) that performs bulk data operations. The risk is high because misconfiguration or injection via job parameters could corrupt healthcare data, violate HIPAA compliance, or cause service disruption.
From the tool's definition Tool name 'start_fhir_import_job' and description 'Start a FHIR import job to load data into HealthLake' indicate this triggers an external operation (job initiation) whose effects depend on arguments (which data source, target configuration, etc.).
Documented attack patterns abuse exactly the kind of access start_fhir_import_job gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon SageMaker AI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for start_fhir_import_job:
{
"version": "1",
"default": "deny",
"tools": {
"start_fhir_import_job": {
"limits": [
{
"counter": "start_fhir_import_job_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
} start_fhir_import_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.
Free to start. No card required.
Start a FHIR import job to load data into HealthLake. It is categorised as a Execute tool in the Amazon SageMaker AI MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Amazon SageMaker AI MCP Server MCP server in PolicyLayer and add a rule for start_fhir_import_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 Amazon SageMaker AI MCP Server. Nothing to install.
start_fhir_import_job is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the start_fhir_import_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.
Set action: deny in the PolicyLayer policy for start_fhir_import_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.
start_fhir_import_job is provided by the Amazon SageMaker AI MCP Server MCP server (awslabs.sagemaker-ai-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Amazon SageMaker AI MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
