Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install excalidraw-diagram-server

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent learns to build an MCP server that generates an HTML page containing an Excalidraw canvas, with its elements, scene format and progressive streaming. The diagram renders in interfaces that support the MCP Apps extension.
