Why generate_infrastructure_code needs a policy

The name suggests generating infrastructure code (e.g., CloudFormation, Terraform, CDK), which at minimum is a Write operation producing code artifacts, but could also involve executing or deploying infrastructure changes. Given the AWS context and sibling tools that include policy attachment and audit operations, this tool likely produces code that could trigger infrastructure provisioning.

From the tool's definition Tool name 'generate_infrastructure_code' — description is empty and uninformative.

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

POLICY

How to control generate_infrastructure_code

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

policy.json

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

generate_infrastructure_code 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 — 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 generate_infrastructure_code

What does the generate_infrastructure_code tool do? +

generate_infrastructure_code. It is categorised as a Execute tool in the AWS MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on generate_infrastructure_code? +

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

What risk level is generate_infrastructure_code? +

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

Can I rate-limit generate_infrastructure_code? +

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

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

generate_infrastructure_code is provided by the AWS MCP server (@awslabs/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every AWS tool call.

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