# (per-client installs, since v2 is not a workspace); `npm pack` runs `prepack`
# (`npm run build`) and emits `modelcontextprotocol-inspector-<version>.tgz`.

# from `npm i -g @modelcontextprotocol/inspector`. The package's postinstall
# early-exits under node_modules, and the tarball ships only each client's
# build/ output, so there is nothing to build here.
