Your agent creates architecture diagrams and flowcharts programmatically, sees its own work via screenshots , fixes layout problems, and exports .excalidraw files you can commit next to your code. One canvas, three ways to drive it: - Agent Skill + CLI — recommended for coding agents (Claude Code, Codex CLI, Cursor, OpenCode): npx -y mcp-excalidraw-server . Zero config, auto-starts the canvas, composable JSON in/out. - MCP Server — 26 tools over stdio for any Model Context Protocol client (Claude Desktop, Cursor, Codex CLI, Antigravity, ...). Speaks MCP 2026-07-28 ( server/discover , per-request meta envelope, tool calls without a handshake) and stays compatible with 2025-era clients that open with initialize . - REST API — plain HTTP for LangChain and custom frameworks. Core drawing runs fully local (Node ≥ 20, MIT licensed) — no API keys. Mermaid conversion runs in the local browser canvas; share is optional and uploads an encrypted scene to excalidraw.com. Demo AI agent creates a complete architecture diagram from a single prompt (4x speed).
