MCP server for Adyen Checkout API v71 — the global enterprise payments rail used by iFood, Uber, Spotify, and AirBnB in LatAm.

Distinct from every other server in our catalog: it's the one gateway enterprise merchants choose when a single contract has to cover BR + EU + US + APAC.

Install

npm install @codespar/mcp-adyen

Environment

ADYEN_API_KEY="..."              # X-API-Key value, secret
ADYEN_MERCHANT_ACCOUNT="..."     # Merchant account code injected into every call
ADYEN_ENV="test"                 # test | live. Default: test.
ADYEN_LIVE_URL_PREFIX="..."      # Required when ADYEN_ENV=live. Your merchant-specific prefix from Customer Area.

URL routing

• ADYEN_ENV=test → https://checkout-test.adyen.com/v71
• ADYEN_ENV=live → https://<ADYEN_LIVE_URL_PREFIX>-checkout-live.adyenpayments.com/checkout/v71

Live calls fail fast if ADYEN_LIVE_URL_PREFIX is missing.

Run

# stdio (default)
npx @codespar/mcp-adyen

# HTTP
MCP_HTTP=true MCP_PORT=3000 npx @codespar/mcp-adyen

Scope

This v0.1 covers Checkout API v71 only. Separate packages for Adyen Payouts, Management, and Balance Platform APIs follow when demand emerges — each has distinct auth, URL prefix rules, and use cases.

Enterprise

Need governance, budget limits, and audit trails for agent payments? CodeSpar Enterprise adds policy engine, payment routing, and compliance templates on top of these MCP servers.

Authentication

Set these environment variables before launching the server:

• ADYEN_API_KEY (required, secret) — Adyen API key (generated in Customer Area → Developers → API credentials)
• ADYEN_MERCHANT_ACCOUNT (required) — Adyen merchant account code (appears in most request bodies)
• ADYEN_ENV — test | live. Defaults to test.
• ADYEN_LIVE_URL_PREFIX — Required when ADYEN_ENV=live. Your merchant-specific prefix, e.g. 1797a841fbb37ca7-AdyenDemo
