Shared visual canvas (Excalidraw) for collaborative whiteboarding between AI agents and humans.

Napkin is a shared Excalidraw canvas for agent + human collaboration. I love using AI assistants for everyday tasks — design, programming, and brainstorming. I’ve always found visual thinking helpful, but there was a gap: I could describe something, and the agent could describe it back, but we couldn’t point to the same thing. What if my agent and I could share a whiteboard — where I draw, it…

Read out of the source npm actually ships, at scan time. The package was never executed. Tools registered dynamically at runtime, or hidden inside bundled or minified code, can be missed — so this is a floor on the tool surface, not a complete census of it.

Tool names and descriptions are written by the publisher and shown verbatim as inert text.

I’ve always found visual thinking helpful, but there was a gap: I could describe something, and the agent could describe it back, but we couldn’t point to the same thing. What if my agent and I could share a whiteboard — where I draw, it responds, and we build together? Napkin works with any MCP-capable agent. For true two-way…
