People connecting this server to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

One of 127 MCP servers published from codespar/mcp-dev-latam. Stars and repository activity are shared across all of them. See all 127 →

Claude Code

claude mcp add codespar-mcp-dev-latam-packages-argentin -- npx -y @codespar/mcp-payway

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "codespar-mcp-dev-latam-packages-argentin": {
      "command": "npx",
      "args": [
        "-y",
        "@codespar/mcp-payway"
      ]
    }
  }

Limitations (from the README)

- Amounts are integers in minor units: 50000 = ARS 500.00. - payment_method_id identifies the card brand (1 = Visa, 31 = Mastercard, 15 = Maestro, …). - site_transaction_id is the merchant-side idempotency anchor - unique per sale. - This server never invents card data; agents must collect PAN/expiry/CVV from the user or a vault.
