move_diagram · RapidChart MCP Server MCP: Risk & Policy

WHAT IT DOES

What move_diagram does on RapidChart MCP Server

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

WHY IT NEEDS A POLICY

Why move_diagram needs a policy

This operation modifies diagram metadata (folder/workspace assignment) but does not delete or destroy the diagram itself—the action is reversible (a diagram can be moved back). It does not create new data (ruling out simple Write category upgrade), nor does it execute arbitrary code or trigger external side effects.

From the tool's definition Tool name 'move_diagram' with description 'Move a diagram to a different folder or workspace' indicates modifying the organizational location/metadata of an existing diagram.
