packkit-mcp

packkit-mcp

The Packkit Model Context Protocol server — let AI agents (Claude Desktop, Cursor, VS Code, …) scaffold and upgrade modern projects as a native tool. It fronts every Packkit generator through the @packkit/core protocol, so the same tools work across languages:

• JavaScript / TypeScript — create-packkit (libraries, CLIs, services, SPAs, monorepos)
• Python — create-packkit-py (libraries, CLIs)

Adding a language later is one registry.register(...) line here — the tools don't change.

Install

Point your MCP client at the published package (no install needed — npx fetches it):

{
  "mcpServers": {
    "packkit": {
      "command": "npx",
      "args": ["-y", "packkit-mcp"]
    }
  }
}

Tools

Tool	What it does
list_generators	List every generator (language target) with maturity + capabilities. Start here.
list_presets	List a generator's presets (experimental hidden unless asked).
get_generator_schema	A generator's full option schema (options, choices, defaults).
generate_project	Preview a project (file tree + stack + deployment contract), or write: true to scaffold to disk.
plan_upgrade	Baseline-aware three-way upgrade plan for an existing project — template changes vs your edits, writes nothing.

The typical flow: list_generators → list_presets / get_generator_schema → generate_project. All generation is protocol-driven; the server holds no language-specific logic.

Develop

npm install
npm run smoke     # boot the server over MCP stdio and exercise both generators
npm run check     # server.json sync check + smoke (what CI runs)

Releases are automated with Changesets — see RELEASING.md.
