node_move · Voog MCP: Risk & Policy

WHAT IT DOES

What node_move does on Voog

AI agents use node_move 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 node_move needs a policy

This tool modifies the page tree structure by moving or reordering nodes, which is a reversible change. It does not delete data (thus not Destructive), does not execute arbitrary code (thus not Execute), and does not involve financial operations. The blast radius is limited to page structure changes within the CMS, making it Write-level risk.

From the tool's definition Tool name 'node_move' combined with description 'Move/reorder a node within the page tree (PUT' indicates a modification operation. The PUT HTTP method and 'move/reorder' language confirm this creates or modifies the structure reversibly.

Verdict

node_move Rate-limited

node_move stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
