4 tools observed

02Execution model

Runs locally over stdio — the server process executes on your machine with your user's privileges. Vet the source and package before granting access.

Installs via npx (`npx -y @21st-dev/magic@latest`) — it pulls and executes third-party code; pin versions and review the source.
