WHAT IT DOES

What create_api_key does on Amazon MQ MCP Server

WHY IT NEEDS A POLICY

Why create_api_key needs a policy

Creating an API key is a reversible write operation that generates new credentials and stores them in the system. This is less severe than destructive actions, but more severe than simple reads. Severity is medium because misuse could expose API keys or create unauthorized access paths, though the operation itself is not irreversible and does not directly move money or execute arbitrary code.

From the tool's definition Tool name is 'create_api_key'; based on API key creation patterns in AWS and MCP contexts, this generates and stores new credentials.
