create_mindmap · StarUML MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_mindmap does on StarUML MCP Server

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

WHY IT NEEDS A POLICY

Why create_mindmap needs a policy

The tool creates a new mindmap diagram within StarUML, a reversible write operation. It does not execute arbitrary code, delete data, or produce financial/external system effects. The blast radius is limited to local diagram generation within the design tool. Severity is low because mindmap creation is a benign design activity with no destructive or operational impact.

From the tool's definition Tool named 'create_mindmap' with description '创建思维导图 (Mindmap)' indicates creation of a new diagram artifact. This parallels sibling tools like create_class_diagram, create_sequence_diagram, etc., which are write operations that create new design assets.
