npm 12 blocks install scripts of unapproved packages under `npx` and `npm install -g` (its allow-scripts policy). The postinstall download never ran, so `npx -y idx-mcp` exited with "installed binary not found" and MCP clients saw only "Connection closed". Hermes Agent hits this by default: it runs a bare `npx` with its own npm 12. The launcher now runs the installer itself when the binary is missing, logging to stderr so the idx-mcp stdout channel stays clean. This also covers pnpm 10+ and bun, which skip dependency scripts by default. npm-smoke installs idx-mcp with --ignore-scripts and checks that the first run still starts cleanly.
