group_nodes · Claude Talk to Figma MCP: Risk & Policy

WHAT IT DOES

What group_nodes does on Claude Talk to Figma MCP

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

WHY IT NEEDS A POLICY

Why group_nodes needs a policy

Grouping nodes in Figma is a reversible modification operation that changes the structure and organization of design elements but does not delete or permanently destroy data. It aligns with the Write category (creates or modifies data reversibly). Severity is medium because misuse could disorganize a design document, requiring manual correction, but the impact is limited in scope and easily undone.

From the tool's definition Tool performs 'Group nodes in Figma', which creates a new grouping structure that modifies the document's node hierarchy. Figma groups are reversible organizational elements (can be ungrouped), making this a write operation rather than destructive.
