WHAT IT DOES

What start_fhir_import_job does on CloudWatch Application Signals MCP Server

AI agents invoke start_fhir_import_job to trigger actions in CloudWatch Application Signals 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.

THE RISK

High Risk

Why start_fhir_import_job needs a policy

Starting an import job is an Execute action because it triggers an external operation (data loading into HealthLake) whose outcome and impact depend on job parameters and the nature of imported data. The tool initiates a process that runs independently, making it Execute rather than Write.

From the tool's definition The tool 'start_fhir_import_job' performs an action that 'Start[s]' and 'load[s] data', which are initiating operations with external side effects.

Documented attack patterns abuse exactly the kind of access start_fhir_import_job gives an agent:

POLICY

How to control start_fhir_import_job

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

policy.json

{
  "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.

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_import_job

What does the start_fhir_import_job tool do? +

Start a FHIR import job to load data into HealthLake. It is categorised as a Execute tool in the CloudWatch Application Signals MCP Server 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_import_job? +

Register the CloudWatch Application Signals 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 CloudWatch Application Signals MCP Server. Nothing to install.

What risk level is start_fhir_import_job? +

start_fhir_import_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_import_job? +

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.

How do I block start_fhir_import_job completely? +

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.

What MCP server provides start_fhir_import_job? +

start_fhir_import_job is provided by the CloudWatch Application Signals MCP Server MCP server (awslabs.cloudwatch-applicationsignals-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 CloudWatch Application Signals MCP Server tool call.

Start from CloudWatch Application Signals MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
