Creating a Pix Charge

Step 1: Get the Pix Account UID

First, list available Pix accounts to get the pix_account_uid:

Use tool: list_charge_pix_accounts

Step 2: Create the Pix Charge

Use the create_charge_pix tool with the required parameters:

Instant Pix (e-commerce, delivery):

{
  "amount": 150.00,
  "pix_account_uid": "018df180-7208-727b-...",
  "expire_at": "2026-01-31T12:30:00-03:00",
  "registration_kind": "instant",
  "payer": {
    "document_number": "111.321.322-09",
    "name": "João da Silva"
  },
  "external_id": "order_12345"
}

Billing Pix (invoices, subscriptions):

{
  "amount": 500.00,
  "pix_account_uid": "018df180-7208-727b-...",
  "expire_at": "2026-02-10T23:59:59-03:00",
  "registration_kind": "billing",
  "payer": {
    "document_number": "12.345.678/0001-90",
    "name": "Company LTDA"
  },
  "fine_type": "percentage",
  "fine_percentage": 2.0,
  "interest_type": "monthly_percentage_calendar",
  "interest_percentage": 1.0,
  "revoke_days": 30
}

Step 3: Get the QR Code

The initial response may not contain the QR Code (asynchronous registration). To get it:

1. Poll the charge using get_charge_pix with the returned UID
2. Check registration_status: When it’s confirmed, the qrcode field will be populated

Use tool: get_charge_pix
Parameters: { "uid": "019c0cbe-f018-717e-..." }

MCP Server Setup

Claude Desktop Configuration

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "kobana-charge": {
      "command": "npx",
      "args": ["-y", "kobana-mcp-charge"],
      "env": {
        "KOBANA_ACCESS_TOKEN": "your_access_token"
      }
    }
  }
}

Sandbox Environment

{
  "mcpServers": {
    "kobana-charge": {
      "command": "npx",
      "args": ["-y", "kobana-mcp-charge"],
      "env": {
        "KOBANA_ACCESS_TOKEN": "your_sandbox_token",
        "KOBANA_API_URL": "https://api-sandbox.kobana.com.br"
      }
    }
  }
}

Claude Code Configuration

Add to .mcp.json in your project root:

{
  "mcpServers": {
    "kobana-charge": {
      "command": "npx",
      "args": ["-y", "kobana-mcp-charge"],
      "env": {
        "KOBANA_ACCESS_TOKEN": "your_access_token"
      }
    }
  }
}

Remote MCP (Hosted)

{
  "mcpServers": {
    "kobana-charge": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.kobana.com.br/charge/mcp",
        "--header",
        "Authorization: Bearer your_access_token"
      ]
    }
  }
}

Best Practices

1. Always get the Pix Account first – Use list_charge_pix_accounts to get available accounts
2. Poll for QR Code – Use get_charge_pix to check registration status
3. Use external_id – Track charges in your system
4. Set revoke_days – Required for interest/fines on Billing Pix
5. Validate CPF/CNPJ – Before creating the charge
6. Test in sandbox – Configure sandbox environment first
