delete_user

Delete an IAM user. Args: user_name: The name of the IAM user to delete force: If True, removes all attached policies, groups, and access keys first confirmed: Must be true to confirm this write operation Returns: Dictionary containing deletion status

Part of the AWS IAM MCP Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents may call delete_user to permanently remove or destroy resources in AWS IAM MCP Server. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.

Without a policy, an AI agent could call delete_user in a loop, permanently destroying resources in AWS IAM MCP Server. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.

Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

    rules:
      - action: deny
        reason: "Blocked by default — enable with approval"

What does the delete_user tool do? +

Delete an IAM user. Args: user_name: The name of the IAM user to delete force: If True, removes all attached policies, groups, and access keys first confirmed: Must be true to confirm this write operation Returns: Dictionary containing deletion status. It is categorised as a Destructive tool in the AWS IAM 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_user? +

Add a rule in your Intercept YAML policy under the tools section for delete_user. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the AWS IAM MCP Server MCP server.

What risk level is delete_user? +

delete_user 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_user? +

Yes. Add a rate_limit block to the delete_user rule in your Intercept 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_user completely? +

Set action: deny in the Intercept policy for delete_user. 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_user? +

delete_user is provided by the AWS IAM MCP Server MCP server (awslabs.iam-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
