Tools of draw.io
	Description		Read-only	Idempotent	Open world
`create_diagram`Creates and displays an interactive draw.io diagram from Mermaid.js syntax or draw.io XML — provide exactly one. Choose the format first. Use `xml` for diagrams of boxes and lines up to about 30 shapes: flowcharts, pipelines, decision trees, org charts, ER schemas, UML class, state and use case diagrams, mind maps, timelines, architecture, cloud and network diagrams, swimlanes, UI mockups, floor plans and anything with stencils. You place every shape yourself, laid out for the chat view (see the XML reference). Use `mermaid` for sequenceDiagram, gantt, gitGraph, pie, journey, quadrantChart, xychart-beta, sankey-beta, requirementDiagram, C4Context/C4Container/C4Component, block-beta, packet-beta, kanban, radar-beta, treemap-beta, treeView-beta, venn-beta, ishikawa-beta, zenuml, wardley-beta, eventmodeling, and for flowcharts, class and state diagrams of more than about 30 shapes (flowcharts with postLayout elk). Whenever the user asks for draw.io XML or no Mermaid, use XML for the rest of the conversation. Call `get_drawio_reference` before your first diagram in a conversation, once per format, with the format you chose: "mermaid" has the syntax for every type (a misspelled header renders blank), "xml" the styles, layout grid, edges, containers, layers and dark mode. Call `search_shapes` first for industry icons (AWS, Azure, GCP, Cisco, Kubernetes, P&ID, electrical) or logos. XML essentials: <mxGraphModel adaptiveColors="auto"><root><mxCell id="0"/><mxCell id="1" parent="0"/>…</root></mxGraphModel>. Every cell has a unique id. Vertices: vertex="1" with <mxGeometry x y width height as="geometry"/>. Edges: edge="1" with source and target, always with a child <mxGeometry relative="1" as="geometry"/>. Put html=1 in every style and XML-escape HTML in values (< > & "). No XML comments. Don't add waypoints. Place the shapes yourself (no postLayout) and set `routing: "libavoid"` only when an edge would otherwise cross a shape.

`get_drawio_reference`Returns the draw.io diagram generation reference as Markdown. Format "xml": styles, the layout grid, edges, containers, swimlanes, layers, tags, metadata, dark mode, the layout and routing passes, and the well-formedness rules for create_diagram's xml. Format "mermaid": the header keyword and syntax hints for every Mermaid type draw.io supports, flowchart styling and the ELK layout. Call it once per format and conversation, before the first diagram in that format; the reference stays valid for the rest of the conversation.

`search_shapes`Search the draw.io shape library by keywords. Returns matching shapes with their exact style strings, dimensions, and titles. Covers ~10,000 built-in stencils (cloud architecture, network topology, P&ID, electrical, Cisco, Kubernetes, BPMN) and, when those are sparse, supplements results with the draw.io icon service (brand/product logos and general-purpose concept icons, e.g. 'react', 'slack', 'shopping cart', 'solar panel'). Use ONLY for diagrams that need industry-specific, branded, or pictorial icons. Do NOT use for standard diagram types like flowcharts, UML, ERD, org charts, or mind maps — these use basic geometric shapes (rectangles, diamonds, circles, cylinders) that are already covered in the XML reference. Also skip if the user asks to use basic/simple shapes or says not to search. The style string from the results can be used directly in mxCell style attributes.
