Niubiz

Peru's dominant card acquirer (ex-VisaNet, 300k+ merchants). Inbound card charges through the security-token flow.

MIT · runs locally with your own credentials

Quickstart

Install, set the credentials, make the first call.

Pick your client. The server runs locally over stdio, with your own credentials.

Tools

What your agent can call.

Fetch the Niubiz API bearer token (POST /api.security/v1/security, Basic auth). Other tools fetch and cache this automatically — call it explicitly only to verify credentials or force a refresh.

Create a checkout session (POST /api.ecommerce/v2/ecommerce/token/session/{merchantId}). Returns the sessionKey the Niubiz checkout form needs. Send the purchase amount and the customer's IP for antifraud scoring.

Authorize a purchase (POST /api.authorization/v3/authorization/ecommerce/{merchantId}). Pass the transactionToken the Niubiz checkout form returned after the customer entered the card, plus your purchaseNumber and the amount.

Reverse (void) an authorization (POST /api.authorization/v3/reverse/ecommerce/{merchantId}). Same-day undo of an authorized transaction by transactionId or purchaseNumber.

Compatibility

MCP is a protocol. Any client that speaks it can mount this server.

codespar_discover lists this server's tools, but a project with a test key cannot call them: its sandbox is not fully configured in the runtime.

Start in seconds.

Add the config above, set the variables, and your agent calls the tools.
