# mcp-cielo

Wires Cielo payments into your coding agent: card sales, boleto, Pix, recurring charges and payment links, as 22 callable tools. Handy when billing logic lives in the repo you are editing.

## What it does

The server talks to the Cielo acquiring API on the agent's behalf. You can open a card sale, capture one that was only pre-authorized, and void it in full or in part. Boleto and Pix are covered too, the latter with a QR code. Recurring credit card plans are managed from the same place: change the amount, move the next charge date, pause the plan, bring it back.

Stored card tokens let you charge a customer again without asking for the card number, and a zero-dollar authorization checks a card without moving money. Authentication uses MerchantId and MerchantKey headers, so you need both credentials from the Cielo developer portal. Testing runs against the Cielo sandbox once `CIELO_SANDBOX=true` is set; the host switches to `apisandbox.cieloecommerce.cielo.com.br`.

One thing to watch: the tool table lists Pix, debit, wallets and anti-fraud, while the roadmap in the same repository still marks several of those as planned for version 0.2. Check which tools actually load before you build a flow around them. Debit sales additionally require 3DS authentication.

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