What install_galaxy_role does on Ludus FastMCP
AI agents invoke install_galaxy_role to trigger actions in Ludus FastMCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why install_galaxy_role is rated High
Installing an Ansible Galaxy role is an external operation that pulls and executes third-party code/configuration into the cyber range environment. This falls under Execute due to the external operation and code installation nature. Severity is high because installing arbitrary roles could introduce malicious code or misconfigure the environment, but without a description, confidence is moderate.
From the tool's definition Tool name 'install_galaxy_role' suggests installing an Ansible Galaxy role into the environment. The description is empty and uninformative, lowering confidence.
