Excalidraw
The Mcp_excalidraw server enables AI agents to create and interactively control live Excalidraw diagrams through a persistent canvas with real-time synchronization, offering 26 MCP tools for element-level CRUD operations, canvas inspection via `describe_scene` and `get_canvas_screenshot`, and iterative diagram refinement. It solves the problem of enabling programmatic, element-by-element diagram creation and adjustment by agents, contrasting with one-shot prompt-to-diagram approaches by maintaining state and allowing agents to view, analyze, and modify canvas contents dynamically. The server integrates with Claude Desktop, Cursor, Claude Code, Codex CLI, and other MCP-compatible clients through both an MCP server interface and portable agent skill.

Excalidraw MCP Server, CLI & Agent Skill
mcp-excalidraw-server gives AI agents a live Excalidraw canvas they can draw on, look at, refine, and save into your repo. 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:
