stop_scan · Amazon Translate MCP Server MCP: Risk & Policy

WHAT IT DOES

What stop_scan does on Amazon Translate MCP Server

AI agents invoke stop_scan to trigger actions in Amazon Translate 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

Why stop_scan needs a policy

Stopping a security scan is an Execute action—it triggers an external operation (terminating a running scan) whose effects are immediate and depend on which scan is targeted. While not destructive (the scan data is preserved) or writes new data, it actively intervenes in an ongoing operation.

From the tool's definition Tool named 'stop_scan' with description 'Stop a running security scan' indicates execution of a command to terminate an active process.

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

POLICY

How to control stop_scan

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

policy.json

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

stop_scan 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 Amazon Translate MCP Server — 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 stop_scan

What does the stop_scan tool do? +

Stop a running security scan. It is categorised as a Execute tool in the Amazon Translate 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 stop_scan? +

Register the Amazon Translate MCP Server MCP server in PolicyLayer and add a rule for stop_scan: 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 Translate MCP Server. Nothing to install.

What risk level is stop_scan? +

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

Can I rate-limit stop_scan? +

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

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

stop_scan is provided by the Amazon Translate MCP Server MCP server (awslabs.amazon-translate-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
