Unblockpay tools (13, 7 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • cancel_transactionwrite action

    Cancel a transaction. Only valid while status is 'awaiting_deposit' — UnblockPay's API returns 422 once the deposit has been received.

  • create_customerwrite action

    Create an individual or business customer (KYC mother). Business customers require date_of_incorporation; both types use 3-letter ISO country codes (BRA/USA/MEX). Returns { id, status: 'pending', verification: { verification_link } }.

  • create_external_accountwrite action

    Register a fiat receiver account (BRL Pix, USD wire, EUR SEPA, MXN SPEI). Skippable for BRL Pix payouts — pass pix_key + document directly on /payout instead.

  • create_payinwrite action

    Create a fiat → stablecoin pay-in referencing a quote_id. Sandbox min: 150 BRL / payout-side equivalents. Response carries { id, status: 'awaiting_deposit', sender_deposit_instructions: { deposit_address: '<Pix Copy & Paste EMV>' }, transaction_link }.

  • create_payoutwrite action

    Create a stablecoin → fiat payout referencing a quote_id. customer_id is REQUIRED at the top level (404 'Customer not found' otherwise). Pix-BR shortcut: pass receiver.pix_key + receiver.document directly to skip external_account registration. Sandbox min: 25 USDC. Response carries { id, status: 'awaiting_deposit', transaction_link, sender_deposit_instructions: { deposit_address: '<blockchain addr

  • create_quotewrite action

    Lock an FX + fee quote for a 5-minute TTL. Same endpoint for both on_ramp (fiat → stablecoin) and off_ramp (stablecoin → fiat). Pass amount on EITHER sender or receiver, not both. Response carries { id, expires_at, commercial_quotation, fees }.

  • create_walletwrite action

    Create a stablecoin wallet under an APPROVED customer. blockchain selects the network (solana → USDC; ethereum/polygon → USDC/USDT; tron → USDT). Customer must be 'approved' before this succeeds (422 customer_not_allowed otherwise).

  • get_transaction

    Poll transaction status. Lifecycle: awaiting_deposit → processing → completed (or failed / refunded / cancelled / error). Sandbox does NOT auto-progress without a webhook simulation — see UnblockPay's /concepts/transactions docs for the mocked transaction IDs available for status testing.

  • get_verification_details

    Poll the KYC verification state for a customer. Returns { customer_status: 'pending' | 'approved' | 'rejected' | 'partially_rejected', verification_steps: [...] }.

  • list_customers

    List customers under the operator's API key. `limit` is mandatory per UnblockPay's pagination contract.

  • list_external_accounts

    List external accounts under the operator's API key.

  • list_wallets

    List wallets under the operator's API key.

  • verify_customer

    Trigger the KYC verification check for a customer. Sandbox auto-progresses business customers through the hosted KYC flow once documents are uploaded. Idempotent — returns 422 'customer_cannot_be_verified' when already approved (safe to ignore).

MCP Dev LATAM 🌎 Every commerce API your AI agent needs to run a business in Latin America. Brazil 🇧🇷 · Mexico 🇲🇽 · Argentina 🇦🇷 · Colombia 🇨🇴 · Chile 🇨🇱 · Peru 🇵🇪 · plus 4 agentic payment protocols. MCP servers for LATAM commerce · live in the official MCP Registry · MIT License Machine-readable catalog: codespar.dev/api/servers Catalog · Quick Start · Agentic Protocols · All Servers · Contribute

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 Latin America, where every service has its own API, auth pattern, and quirks (mTLS for BACEN Pix v2, JWT-RSA for STP-SPEI, AFIP web services, contract-gated developer portals, and on).

Meanwhile, four agentic payment protocols are shipping in parallel — checkout protocols (Stripe ACP, Google UCP), authorization layers (AP2), and micropayment rails (x402) — and none of them compose cleanly with each other or with the regional rails businesses actually run on.

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

The Solution

Each MCP server in this repo wraps a real provider — payments, fiscal, logistics, messaging, banking, ERP, identity, fraud, crypto, and the agentic protocols — so your agent can operate a complete business workflow.

🛒 Customer places order
  → 💳 Agent charges via Pix (Asaas / Mercado Pago / Zoop)
  → 📄 Agent issues NFe (Nuvem Fiscal / Focus NFe / NFe.io)
  → 📦 Agent generates shipping label (Melhor Envio / Skydropx)
  → 📱 Agent sends tracking via WhatsApp (Z-API / WhatsApp Cloud)
  → 📊 Agent records in ERP (Omie / Bling / Tiny)
  → 🏦 Agent reconciles balance (Stark Bank / Itaú / BTG)

Six systems. Zero human intervention. One agent.

Agentic Payment Protocols

Four servers for the emerging agentic payment stack:
