layouts_pull · Voog MCP: Risk & Policy

WHAT IT DOES

What layouts_pull does on Voog

AI agents use layouts_pull to create or update resources in Voog — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Voog environment.

WHY IT NEEDS A POLICY

Why layouts_pull needs a policy

This tool retrieves layout data (Read) but crucially also writes it to persistent storage ('write per-layout'). Writing local files is a reversible modification action that could overwrite existing layouts. While not destructive on the CMS itself, it modifies the local development state and is categorized as Write rather than Read due to the persistent storage write operation.

From the tool's definition Tool description states 'write per-layout', indicating it writes data to the local filesystem. The action fetches layouts and components from the remote CMS (/layouts endpoint) and persists them locally.
