The Problem

AI agents can write code, analyze data, and chat. But they can't operate a business — collect payments, issue invoices, ship products, or notify customers. Especially not in Brazil, where every service has its own API, auth pattern, and quirks.

Meanwhile, five categories of agentic payment infrastructure are shipping in parallel — checkout protocols, authorization layers, micropayment rails, identity frameworks, and issuing tools — and none of them compose cleanly.

MCP Dev Brasil bridges both gaps. Traditional Brazilian services + the new agentic payment protocols, all accessible through a single MCP interface.

The Solution

MCP Brasil gives AI agents typed tools to interact with Brazilian APIs and agentic payment protocols. Each server wraps a real service — payments, fiscal, logistics, messaging, banking, ERP, crypto, and now agentic protocols — so your agent can operate a complete business workflow.

🛒 Customer places order
  → 💳 Agent charges via Pix (Zoop)
  → 📄 Agent issues NFe (Nuvem Fiscal)
  → 📦 Agent generates shipping label (Melhor Envio)
  → 📱 Agent sends tracking via WhatsApp (Z-API)
  → 📊 Agent records in ERP (Omie)
  → 🏦 Agent reconciles balance (Stark Bank)

Six systems. Zero human intervention. One agent.

Agentic Payment Protocols

"The bridge looks more like middleware than a protocol." — The middleware is MCP.

Three new servers that bridge the emerging agentic payment stack:

Protocol	Server	Tools	What it does
Google UCP	`@codespar/mcp-ucp`	21	Universal Commerce Protocol — agentic shopping, cart, checkout, orders, delivery, identity. Google's full commerce stack for AI agents.
Stripe ACP	`@codespar/mcp-stripe-acp`	16	Agentic Commerce Protocol — AI agent checkout, payment delegation, products, invoices. Live in ChatGPT with 1M+ Shopify merchants.
x402	`@codespar/mcp-x402`	10	HTTP-native micropayments by Coinbase — when an agent hits a 402, it pays USDC on Base/Solana and retries. Pure HTTP, no checkout UI.
AP2	`@codespar/mcp-ap2`	13	Google's Agent-to-Agent Payment Protocol — authorization, audit trails, scoped spend limits. 60+ partners including Visa, Mastercard, Stripe, PayPal.

The Autonomy Spectrum

Each protocol sits at a different level of agent autonomy:
