AI agents invoke start_dicom_import_job to trigger actions in Amazon ECS 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.
A DICOM import job is an external operation whose effects depend on the source data and job configuration. This falls under Execute (triggers external operations), not Read (passive data retrieval) or Write (simple data modification). The high severity reflects that misused import jobs could ingest malicious or corrupted medical data into a healthcare system, affecting data integrity and potentially patient safety.
From the tool's definition Tool name 'start_dicom_import_job' indicates initiation of an automated job process that imports DICOM (medical imaging) data. The server context is 'automating containerization and deployment' which suggests execution of background tasks.
Documented attack patterns abuse exactly the kind of access start_dicom_import_job gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon ECS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for start_dicom_import_job:
{
"version": "1",
"default": "deny",
"tools": {
"start_dicom_import_job": {
"limits": [
{
"counter": "start_dicom_import_job_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
} start_dicom_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.

start_dicom_import_job. It is categorised as a Execute tool in the Amazon ECS MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Amazon ECS MCP Server MCP server in PolicyLayer and add a rule for start_dicom_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 ECS MCP Server. Nothing to install.
start_dicom_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_dicom_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_dicom_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_dicom_import_job is provided by the Amazon ECS MCP Server MCP server (awslabs.ecs-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Amazon ECS MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
