THE RISK

Critical Risk

Why delete needs a policy

The name 'delete' indicates an irreversible destructive operation. Without a description, we cannot narrow the scope, but any delete operation in AWS carries critical risk due to potential permanent loss of infrastructure, data, or configurations. The lack of descriptive detail lowers confidence slightly, but the semantic meaning of 'delete' is unambiguous and maps directly to the Destructive category.

From the tool's definition Tool is named 'delete' with no description provided. In AWS Serverless contexts, delete operations typically remove resources irreversibly (e.g., Lambda functions, API Gateways, DynamoDB tables, databases).

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

POLICY

How to control delete

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete"
  ]
}

delete disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register AWS Serverless 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 delete

What does the delete tool do? +

delete. It is categorised as a Destructive tool in the AWS Serverless MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on delete? +

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

What risk level is delete? +

delete is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit delete? +

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

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

delete is provided by the AWS Serverless MCP Server MCP server (awslabs.aws-serverless-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 Serverless MCP Server tool call.

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