Create a new Excalidraw diagram from structured node and connection data.

The LLM provides a relationship map - this tool handles layout, styling, and rendering. No need to specify coordinates.

Convert Mermaid flowchart syntax into an Excalidraw diagram.

Supports the mermaid flowchart subset that AI agents commonly generate:

• Directions: graph TD, LR, BT, RL

• Node shapes: [text], {text}, ((text)), ([text])

• Edge types: -->, ---, -.-> ==> with |label|

• Subgraphs: subgraph Title ... end

Component types are auto-detected from node labels (e.g., a node labeled "PostgreSQL DB" automatically gets database styling).

Modify an existing Excalidraw diagram created by this tool.

Supports iterative editing: add components, remove nodes, update labels, and rewire connections - without recreating the entire diagram.

IMPORTANT: Call get_diagram_info first to understand the current diagram state before making modifications.

Get a structured summary of an existing Excalidraw diagram.

Call this BEFORE modify_diagram to understand what nodes and connections currently exist. The summary includes node ids, labels, component types, and the full connection topology.

Export an .excalidraw file to SVG or PNG image.

Converts an existing .excalidraw diagram into a portable image file without requiring a browser or the Excalidraw application.
