The Collaborative Workspace for Hand-Drawn Diagrams (Website)

ExcaliClaw is a browser-based collaborative workspace that integrates hand-drawn diagramming with AI agent workflows through MCP.

What: The platform offers real-time collaborative whiteboarding with persistent storage, collections for organizing drawings, and deep integration with LLM tools like Claude, Cursor, and VS Code via the Model Context Protocol (MCP).

Why it matters: Integrating visual artifacts into the AI developer workflow acknowledges that hand-drawn diagrams are essential for system architecture communication, and making them programmatically accessible to LLMs bridges the gap between whiteboarding and coding.

Takeaway: Visit excaliclaw.com to link your diagrams to your existing Cursor or Claude environment using the MCP toolset.
