THE RISK

Why build_and_push_image_to_ecr needs a policy

Building and pushing Docker images to ECR involves executing external operations (Docker build, registry push) with effects determined by the image content and registry target. This is an Execute action with high severity because a malicious image could compromise containerized workloads and deployments.

From the tool's definition Tool name 'build_and_push_image_to_ecr' indicates building a Docker image and pushing it to Amazon Elastic Container Registry. Description is empty, limiting evidence.

POLICY

How to control build_and_push_image_to_ecr

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 build_and_push_image_to_ecr:

policy.json

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

build_and_push_image_to_ecr 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.

How do I enforce a policy on build_and_push_image_to_ecr? +

Register the Awslabs Amazon Sns Sqs MCP server in PolicyLayer and add a rule for build_and_push_image_to_ecr: 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 build_and_push_image_to_ecr? +

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

Can I rate-limit build_and_push_image_to_ecr? +

Yes. Add a rate_limit block to the build_and_push_image_to_ecr 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 build_and_push_image_to_ecr completely? +

Set action: deny in the PolicyLayer policy for build_and_push_image_to_ecr. 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 build_and_push_image_to_ecr? +

build_and_push_image_to_ecr 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.
