When you run npm, npx, yarn, pnpm, pnpx, rush, rushx, bun, bunx, pip, pip3, uv, uvx, poetry, pipx or pdm commands, all package downloads are routed through this local proxy, which verifies packages in real-time against **[Aikido Intel - Open Sources Threat Intelligence](https://intel.aikido.dev/?tab=malware)**.
