Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install mcp-apps-ext-apps-sdk

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 registers app tools and resources on the server, writes the view with the App class or the React useApp hook, and sets up a single-file Vite build. It flags the most common errors. You get an MCP Apps application that displays in a compatible host.
