@codespar/mcp-niubiz

MCP server for Niubiz (ex-VisaNet Perú) — Peru's dominant card acquirer, 300k+ merchants. Implements the real ecommerce flow: security token → checkout session → authorization, plus same-day reverse.

Quick Start

Claude Desktop

Add to ~/.config/claude/claude_desktop_config.json:

{
  "mcpServers": {
    "niubiz": {
      "command": "npx",
      "args": ["-y", "@codespar/mcp-niubiz"],
      "env": {
        "NIUBIZ_USER": "your-api-user",
        "NIUBIZ_PASSWORD": "your-api-password",
        "NIUBIZ_MERCHANT_ID": "your-merchant-id",
        "NIUBIZ_ENV": "sandbox"
      }
    }
  }
}

Claude Code

claude mcp add niubiz --env NIUBIZ_USER=... --env NIUBIZ_PASSWORD=... --env NIUBIZ_MERCHANT_ID=... -- npx -y @codespar/mcp-niubiz

Cursor / VS Code

Add the same block to .cursor/mcp.json or .vscode/mcp.json.

Tools (4)

Tool	Endpoint	What it does
get_security_token	POST /api.security/v1/security	Bearer token (cached 20 min; other tools auto-fetch)
create_session_token	POST /api.ecommerce/v2/ecommerce/token/session/{merchantId}	Checkout session with amount + antifraud data
authorize_transaction	POST /api.authorization/v3/authorization/ecommerce/{merchantId}	Authorize with the checkout's transactionToken
reverse_transaction	POST /api.authorization/v3/reverse/ecommerce/{merchantId}	Same-day void of an authorization

The Niubiz flow

Card data never touches this server: the customer types the card into Niubiz's own checkout form (fed by create_session_token), the form returns a transactionToken, and authorize_transaction completes the purchase. This is Niubiz's standard 3-step ecommerce integration.

Authentication

Variable	Required	Description
NIUBIZ_USER	yes	API user
NIUBIZ_PASSWORD	yes	API password
NIUBIZ_MERCHANT_ID	yes	Merchant id (código de comercio)
NIUBIZ_ENV	no	sandbox (default) or production

Enterprise

Need governance, budget limits, and audit trails for agent payments? CodeSpar Enterprise adds policy engine, payment routing, and compliance templates on top of these MCP servers.

Managed tier

This open-source server calls Niubiz's API directly with your credentials. CodeSpar's managed tier routes one interface across every LATAM provider with automatic failover, governance, audit and a credential vault: codespar.dev/agents.
