Scaffold modern npm packages, CLIs, services, and full-stack monorepos from your agent. Three tools: inspect the option schema, preview the generated file tree, and write the project to disk — optionally creating the GitHub repo and pushing to it, or merging into an existing clone without overwriting anything. Also available as a CLI and a web configurator. `npx -y packkit-mcp`
Search @imqueue docs and scaffold typed services & clients for AI coding agents, access CLI and manage your service fleet.
