Why start_batch_translation needs a policy

This tool likely triggers a translation job on AWS services, which constitutes executing an external operation with effects that depend on arguments (documents to translate, target languages, etc.). While not destructive or financial, it commands execution of a computational process.

From the tool's definition Tool name 'start_batch_translation' indicates an operation that initiates a batch process. The empty description prevents confirmation of exact effects, but 'start' combined with 'batch' and 'translation' suggests triggering an external operation (likely AWS…

POLICY

How to control start_batch_translation

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

policy.json

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

start_batch_translation 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 AWS AppSync 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 start_batch_translation

What does the start_batch_translation tool do? +

start_batch_translation. It is categorised as a Execute tool in the AWS AppSync 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_batch_translation? +

Register the AWS AppSync MCP Server MCP server in PolicyLayer and add a rule for start_batch_translation: 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 AWS AppSync MCP Server. Nothing to install.

What risk level is start_batch_translation? +

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

Can I rate-limit start_batch_translation? +

Yes. Add a rate_limit block to the start_batch_translation 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_batch_translation completely? +

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

start_batch_translation is provided by the AWS AppSync MCP Server MCP server (awslabs.aws-appsync-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 AWS AppSync MCP Server tool call.

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