## Why get_ansible_role_vars is rated Low

This tool retrieves configuration variables associated with an Ansible role. It performs a read-only query operation without modifying, creating, or deleting any data. The blast radius of misuse is minimal—unauthorized access to role variables might reveal configuration details but cannot directly alter systems or resources. Therefore, it is classified as 'Read' with low severity.

From the tool's own definition: "Tool name 'get_ansible_role_vars' and description 'Get variables for an Ansible role' indicate a retrieval operation. The verb 'Get' and the context of querying Ansible role variables confirm this is a data retrieval action with no side effects."

## Use case

AI agents call get_ansible_role_vars to retrieve information from Ludus FastMCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
