What create_api does on Amazon MQ MCP Server

AI agents use create_api 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_api needs a policy

The name 'create_api' implies creating a new API resource (Write category). However, the empty description significantly lowers confidence. In the context of an Amazon MQ server for broker management, this could relate to creating API configurations. Since the description is empty, severity is kept at medium and confidence is low.

From the tool's definition Tool name 'create_api' suggests creation of an API resource, which is a write operation. Description is empty and uninformative.
