A Claude Code plugin that scaffolds MPP (Machine Payments Protocol) billing into any API project. It generates production-ready cost tracking, session management, and payment integration code for your framework.

claude install-plugin /path/to/mpp-bundler

Or run Claude with the plugin directory:

claude --plugin-dir /path/to/mpp-bundler

1. Install the plugin
2. Open your API project in Claude Code
3. Run /mpp-bundler:init
4. Follow the prompts to configure providers, pricing, and payment methods

The plugin teaches Claude how to:

• Detect your framework (Next.js, Hono, Express, Elysia, CF Workers, Bun, FastAPI) and API providers (OpenAI, Anthropic, Exa, etc.)
• Generate a mpp-bundle.config.ts with provider pricing, payment methods, and platform premium
• Scaffold runtime code (mpp-bundle.ts) that tracks costs across providers and bundles them
• Wire MPP-compliant middleware into your existing endpoints (402 challenges, payment verification)
• Support three billing models: one-time charge, pay-as-you-go sessions, and SSE per-token streaming

After setting up billing, run /mpp-bundler:add-dashboard to scaffold a cost/revenue dashboard that shows:

• Margin visibility — cost (what you pay providers) vs revenue (what consumers pay you) with margin percentage and health indicator
• Provider breakdown — per-provider and per-model cost/revenue analysis
• Daily trends — time-series chart showing cost vs revenue gap over time
• Endpoint analytics — which endpoints cost the most and generate the most revenue
• Recent transactions — live feed of usage log entries

The dashboard includes a database migration (bundle_usage_log table), a fire-and-forget usage logger wired into track(), 6 admin API endpoints (gated by MPP_ADMIN_KEY), and a dashboard UI (React page for Next.js, standalone HTML for other frameworks).
