io.github.codespar/mcp-ap2 MCP Server

io.github.codespar/mcp-ap2

Google's AP2 protocol for AI agent-to-agent payment authorization, audit, and spend control.

What is the io.github.codespar/mcp-ap2 MCP server?

The io.github.codespar/mcp-ap2 MCP server implements Google's Agent-to-Agent Payment Protocol (AP2), giving AI agents tools for payment authorization, execution, audit trails, and scoped spend limits. It is part of the MCP Dev LATAM catalog and is currently in alpha status, exposing 22 tools for agent-to-agent payment workflows. It targets ecosystems supported by 60+ partners including Visa, Mastercard, Stripe, and PayPal.

mcp-ap2 wraps Google's Agent-to-Agent Payment Protocol (AP2) in an MCP server, letting AI agents authorize and execute payments between agents with audit trails and scoped spend limits. It sits at the "authorization layer" of the agentic payment stack — distinct from checkout-focused protocols like Stripe ACP or Google UCP, and from settlement-layer micropayment protocols like x402. It's marked alpha, part of the larger MCP Dev LATAM catalog of 110 MCP servers covering LATAM commerce APIs and agentic payment protocols.

io.github.codespar/mcp-ap2 MCP server FAQ

What does the mcp-ap2 server do?

It implements Google's AP2 (Agent-to-Agent Payment Protocol), exposing tools to authorize and execute payments between AI agents, with audit trails and scoped spend limits, via MCP.

Is mcp-ap2 free to use?

The package itself is open source (MIT licensed as part of MCP Dev LATAM), but using it requires credentials/API keys from AP2-participating payment providers, which may have their own costs.

How do I install mcp-ap2 in Claude Desktop?

Add it to claude_desktop_config.json with command 'npx' and args '["-y", "@codespar/mcp-ap2@alpha"]', including required API key env vars, since it's an alpha package.

What authentication does mcp-ap2 require?

It requires an API Key, as noted in the payments server table, though specific credential setup depends on the AP2 partner/provider being used.

Is mcp-ap2 stable for production use?

No, it is explicitly labeled 'alpha' in the catalog, meaning it should be considered experimental and installed with the '@alpha' npm tag.

How is AP2 different from Stripe ACP or Google UCP?

AP2 sits at the authorization layer (spend limits, audit trails, agent-to-agent) rather than the application/checkout layer like ACP and UCP, or the settlement layer like x402.

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 that bridge the emerging agentic payment stack:

Protocol	Server	Tools	What it does
Google UCP	`@codespar/mcp-ucp`	20	Universal Commerce Protocol — agentic shopping, cart, checkout, orders, delivery, identity. Google's full commerce stack for AI agents.
Stripe ACP	`@codespar/mcp-stripe-acp`	24	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` <sub>alpha</sub>	22	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:

 Human-in-loop ◄──────────────────────────────► Fully autonomous

  ┌─────────┐   ┌─────────┐   ┌─────────┐   ┌─────────┐
  │   ACP   │   │   UCP   │   │   AP2   │   │   x402  │

The Convergence Stack

┌─────────────────────────────────────────────┐
│  Application Layer        ACP / UCP         │  Chat UX, product discovery
├─────────────────────────────────────────────┤
│  Authorization Layer      AP2 / Mandates    │  Spend limits, audit trails
├─────────────────────────────────────────────┤
│  Tool Layer               MCP  ◄── WE ARE  │  Standardized agent tools
├─────────────────────────────────────────────┤
│  Settlement Layer         x402 / Pix / Card │  On-chain or traditional rails
└─────────────────────────────────────────────┘

MCP Dev LATAM sits at the Tool Layer — the middleware that connects every application, authorization, and settlement protocol through one interface.

Why this matters

Agent needs to buy something
  ├── Full commerce?       → Google UCP (search → cart → checkout → delivery)
  ├── Retail checkout?     → Stripe ACP (create_checkout → complete_checkout)
  ├── API micropayment?    → x402 (pay_request → USDC $0.001 → data returned)
  ├── Agent-to-agent?      → AP2 (authorize_payment → execute_payment)
  └── LATAM merchant?      → Asaas / Mercado Pago / Conekta / Wompi / etc.

All via MCP. Same interface. One agent.

Quick Start

With Claude Desktop

Add to ~/.config/claude/claude_desktop_config.json:

{
  "mcpServers": {
    "stripe-acp": {
      "command": "npx",
      "args": ["-y", "@codespar/mcp-stripe-acp"],
      "env": {
        "STRIPE_API_KEY": "sk_test_..."
      }
    },
    "asaas": {
      "command": "npx",
      "args": ["-y", "@codespar/mcp-asaas"],
      "env": {
        "ASAAS_API_KEY": "your-api-key",
        "ASAAS_SANDBOX": "true"
      }
    }
  }
}

For alpha packages (contract-gated providers like Itaú, Bradesco, Santander, Caixa, BB, BTG, C6, Sicoob, Bradesco, Matera), add @alpha to the install:

npx -y @codespar/mcp-itau@alpha

With any MCP client

npx @codespar/mcp-stripe-acp        # Agentic Commerce Protocol
npx @codespar/mcp-ucp                # Google Universal Commerce Protocol
npx @codespar/mcp-x402               # HTTP micropayments (Coinbase)
npx @codespar/mcp-ap2@alpha          # Agent-to-Agent payment authorization

npx @codespar/mcp-asaas              # BR billing + Pix
npx @codespar/mcp-mercado-pago       # LATAM payments
npx @codespar/mcp-nuvem-fiscal       # NFe / NFSe
npx @codespar/mcp-melhor-envio       # Multi-carrier shipping
npx @codespar/mcp-z-api              # WhatsApp messaging
npx @codespar/mcp-omie               # ERP
npx @codespar/mcp-stark-bank         # Banking
npx @codespar/mcp-brasil-api         # CEP, CNPJ (no key needed!)

Try it now (no API key)

BrasilAPI and BCRA are public — no key required. Try it in your terminal:

npx @codespar/mcp-brasil-api

Then ask your agent: "What is the address for CEP 01001-000?" or "Look up CNPJ 00.000.000/0001-91".

The Complete Loop

This is what makes the LATAM catalog different — not individual connectors, but a complete business workflow across verticals:

Step	Vertical	Example providers	What the agent does
1	💳 Payment	Asaas / Mercado Pago / Zoop	Creates Pix charge, splits to sellers
2	📄 Fiscal	Nuvem Fiscal / NFe.io / Focus NFe	Issues NFe/NFSe when payment confirmed
3	📦 Logistics	Melhor Envio / Correios / Skydropx	Quotes shipping, generates label
4	📱 Messaging	Z-API / WhatsApp Cloud / Twilio	Sends tracking via customer's preferred channel
5	📊 ERP	Omie / Bling / Tiny / Conta Azul	Records order, updates inventory
6	🏦 Banking	Stark Bank / Itaú / BTG	Reconciles balance, creates reports

To orchestrate all six steps with governance, approval workflows, and audit trails — use CodeSpar.

Why MCP?

Model Context Protocol is the open standard for connecting AI agents to external tools. Instead of each agent building its own integrations, MCP provides a typed, discoverable interface that works with Claude, ChatGPT, Cursor, VS Code, and more.

AI Agent (Claude, ChatGPT, Cursor)
    ↕
MCP Server (this repo)
    ↕
LATAM API / Agentic Protocol (Stripe ACP, x402, Asaas, Mercado Pago, NFe.io, etc.)

Each MCP server in this repo:

Exposes typed tools with input/output schemas
Handles authentication (OAuth, mTLS, API keys, Basic Auth, JWT-RSA, signed requests)
Supports dual transport — stdio (default) and Streamable HTTP (--http flag)
Compatible with Claude Managed Agents via MCP Connector
Supports sandbox mode for safe testing
Returns structured JSON responses

Running in HTTP mode

Any server can run as an HTTP server for remote/cloud use:

# stdio (default — local, Claude Desktop, Cursor, Claude Code)
npx @codespar/mcp-asaas

# HTTP (remote — Managed Agents, cloud deployments)
npx @codespar/mcp-asaas --http
# or
MCP_HTTP=true npx @codespar/mcp-asaas

HTTP mode exposes /mcp (Streamable HTTP) and /health (status check).

Alpha vs stable

About a third of the catalog ships under the alpha npm dist-tag. These packages have correct tool schemas and auth flow, but the endpoint paths are best-guesses — typically because the provider's developer portal is contract-gated (BR public banks, AR central authority APIs, MX bank-transfer providers). They're flagged with TODO(verify) in source.

npm install @codespar/mcp-itau@alpha

Stable packages (the majority) install with the default tag:

npm install @codespar/mcp-stripe

Status is shown on every package page at codespar.dev/servers and in each package README.

About CodeSpar

CodeSpar builds commerce infrastructure for AI agents in Latin America — an MCP catalog (this repo), a runtime + SDK (@codespar/sdk on npm, codespar on PyPI), and a managed-tier governance product (AgentGate: programmable wallet, policy engine, CFO-grade audit, fiscal-compliance certifications).

Individual MCP servers are useful. Orchestrating many with governance is powerful. That's what CodeSpar does.
