Why StartAHORunBatch needs a policy

With no description provided, classification relies on the tool name. 'Start' + 'Batch' suggests launching a computational or data-processing job in AWS, which constitutes Execute (triggers an external operation). This is not Read (no query-only nature evident), not Write (not reversible data creation), not Destructive (no deletion indicated), and not Financial (no money movement).

From the tool's definition Tool name 'StartAHORunBatch' suggests initiating a batch operation in AWS (likely AWS Health Omics). The 'Start' verb indicates triggering an external operation whose effects depend on arguments. The description is empty, which reduces confidence.

POLICY

How to control StartAHORunBatch

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

policy.json

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

StartAHORunBatch 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 API 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 StartAHORunBatch

What does the StartAHORunBatch tool do? +

StartAHORunBatch. It is categorised as a Execute tool in the AWS API 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 StartAHORunBatch? +

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

What risk level is StartAHORunBatch? +

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

Can I rate-limit StartAHORunBatch? +

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

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

StartAHORunBatch is provided by the AWS API MCP Server MCP server (awslabs.aws-api-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 API MCP Server tool call.

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