moneydevkit

Add payments to any web app in under 5 minutes. Two supported frameworks: Next.js and Replit (Express + Vite).

Workflow

1. Get credentials

**Option A — MCP:**

There are two MCP servers:

To create a new account:

```

claude mcp add moneydevkit --transport http https://mcp.moneydevkit.com/mcp/

```

After you have credentials, switch to the authenticated MCP for full account control:

```

claude mcp add moneydevkit --transport http https://mcp.moneydevkit.com/mcp/account/

```

**Option B — CLI:**

```bash

npx @moneydevkit/create

```

**Option C — Dashboard:**

Sign up at [moneydevkit.com](https://moneydevkit.com) and create an app.

All options produce two values:

Add both to `.env` (or Replit Secrets, Vercel env vars, etc.). Both are required.

2. Pick a framework and follow its guide

3. Create products (optional)

For fixed catalog items, create products via the dashboard or MCP:

```

mcporter call moneydevkit.create-product name="T-Shirt" priceAmount=2500 currency=USD

```

Then use `type: 'PRODUCTS'` checkouts with the product ID.

For dynamic amounts (tips, donations, invoices), skip products and use `type: 'AMOUNT'` directly.

4. Deploy

Deploy to Vercel (Next.js) or Replit. Ensure `MDK_ACCESS_TOKEN` and `MDK_MNEMONIC` are set in the production environment.

⚠️ Use `printf` not `echo` when piping env vars — trailing newlines cause silent auth failures.

Checkout types

| Type | Use case | Required fields |

|------|----------|----------------|

| `AMOUNT` | Dynamic amounts, tips, invoices | `amount`, `currency` |

| `PRODUCTS` | Sell dashboard products | `product` (product ID) |

Pricing options

Currency

Customers

Collect customer info to track purchases and enable refunds:

```ts

await createCheckout({

// ...checkout fields

customer: { email: '[email protected]', name: 'Jane', externalId: 'user-123' },

requireCustomerData: ['email', 'name'] // show form for missing fields

})

```
