## What it does

This server interfaces agentic environments with Transbank, the dominant payment processor in Chile. It brings 19 tools targeting two payment schemes: redirect-based checkouts with Webpay Plus, and multi-merchant recurring billing with Webpay OneClick Mall.

Your assistant can start new payment sessions and commit funds once the customer returns. It also handles refunds and delayed capture. Authentication headers `Tbk-Api-Key-Id` and `Tbk-Api-Key-Secret` are injected behind the scenes for every outbound request.

Connecting fails without valid `TRANSBANK_COMMERCE_CODE` and `TRANSBANK_API_KEY_SECRET` credentials in the environment. Setting `TRANSBANK_ENV` switches the target endpoint between integration testing and production.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `TRANSBANK_COMMERCE_CODE`, `TRANSBANK_API_KEY_SECRET`, `TRANSBANK_ENV` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
