What ansible-galaxy does on Build
AI agents invoke ansible-galaxy to trigger actions in Build. 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 ansible-galaxy is rated High
ansible-galaxy installs external Ansible collections and roles, which involves downloading and placing executable code/modules onto the system. This is an external operation that modifies the environment by installing packages. The install action is not easily reversible (installed collections affect subsequent playbook runs) and triggers external operations.
From the tool's definition 'Installs or lists Ansible collections and roles from Galaxy or a requirements file' — the install operation downloads and executes external package installation
Attacks that exploit this kind of access
The rule that runs ansible-galaxy safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Build, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ansible-galaxy, this is the rule to start with:
ansible-galaxy stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Build, apply this rule, and every ansible-galaxy call is checked against it from then on.
