Draw.io Skill

Use this skill for all draw.io and diagrams.net work. This skill wraps the configured drawio MCP server; it does not replace the server.

Required workflow

1. Start the draw.io session first.

• Call start_session before creating a new diagram or before inspecting or editing a diagram in a fresh session.

2. Create new diagrams from complete XML.

• Use create_new_diagram with a full mxGraphModel.
• Keep the diagram within a single viewport when practical.

3. Read before editing.

• Always call get_diagram before edit_diagram.
• Do not guess cell IDs.
• Preserve user changes already present in the live session.

4. Export deliverables.
