create_queue · Amazon MQ MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_queue does on Amazon MQ MCP Server

AI agents use create_queue to create or update resources in Amazon MQ MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Amazon MQ MCP Server environment.

WHY IT NEEDS A POLICY

Why create_queue needs a policy

create_queue creates a new messaging queue in Amazon MQ, which is a reversible Write operation that modifies infrastructure state. Severity is high because misconfigured queues could disrupt message routing, consume resources, or create security issues in the broker topology. The empty description prevents higher confidence, but the action is clearly creational (Write) rather than destructive or financial.

From the tool's definition Tool name 'create_queue' indicates creation of a messaging queue resource in Amazon MQ. The sibling tools (add_attachments_to_set, add_communication_to_case, add_inline_policy, add_user_to_group) are all Write operations.

Verdict

create_queue Rate-limited

create_queue stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
