Summary
You'd reach for this when you need Claude to programmatically build and manipulate whiteboard diagrams during a conversation. It exposes operations for creating objects and connectors on collaborative boards, with specific support for C4 architecture diagrams. The server runs over streamable HTTP, so Claude can create visual representations of system designs, flowcharts, or conceptual diagrams as you discuss them. Think of it as giving Claude hands to sketch on a shared whiteboard at Benevolabs' hosted endpoint, useful when you're architecting systems or need to visualize relationships between components in real time rather than just talking through them.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.
