Excalidraw

Excalidraw MCP Server (optional)

The official Excalidraw MCP server (https://mcp.excalidraw.com) supports natural-language diagram generation. It uses Streamable HTTP transport, which isn't supported by the plugin MCP system — users who want it must add it manually to their Claude Code settings.

If the Excalidraw MCP tools are available in the current session, use them for quick one-shot diagrams. Otherwise, use direct JSON generation as described below.
