Mcp Amazon

@codespar/mcp-amazon

MCP server for the Amazon Selling Partner API (SP-API) — the biggest global marketplace, including Amazon BR, Amazon MX, Amazon US, and all EU/FE marketplaces.

For LatAm sellers, Amazon rounds out the marketplace trio already in this catalog:

• Mercado Libre (@codespar/mcp-mercadolibre) — dominant in LatAm generally (BR, AR, MX, CO, CL).
• Shopee (@codespar/mcp-shopee) — heavy in Brazil and rapidly growing regionally.
• Amazon (this package) — global reach, plus Amazon BR/MX for LatAm sellers and cross-border into Amazon US/EU/JP.

Together these three cover essentially every marketplace where a LatAm merchant transacts meaningful GMV.

Authentication

SP-API uses a dual-step Login with Amazon (LWA) flow:

1. Exchange refresh token → access token (1-hour lifetime). The server POSTs to https://api.amazon.com/auth/o2/token with grant_type=refresh_token and your client_id / client_secret / refresh_token. The result is cached in memory until ~1 minute before expiry.
2. Call SP-API with the regional base URL and header x-amz-access-token: <token> plus Content-Type: application/json.

AWS Signature v4 request signing was the historical requirement for SP-API. Amazon removed the SigV4 requirement in 2023 for most tenants, so this server uses LWA-only auth. If your seller is still flagged as requiring SigV4, you will need to wrap amazonRequest with a signer (@aws-sdk/signature-v4) — not included here.

Regional base URLs

• NA (Americas, including BR/US/MX/CA): https://sellingpartnerapi-na.amazon.com
• EU (Europe + India + MENA): https://sellingpartnerapi-eu.amazon.com
• FE (Far East — Japan, Australia, Singapore): https://sellingpartnerapi-fe.amazon.com

Select with AMAZON_REGION. Brazil and the Americas use na.

Notifications

create_subscription is webhook-equivalent for SP-API. Amazon does not push HTTP webhooks directly — instead, you create a destination (SQS queue or EventBridge bus) via POST /notifications/v1/destinations first, then attach subscriptions to that destination. This package covers subscription creation; destination provisioning is a one-time setup typically done via the AWS Console or a deploy script.

Status

0.1.0-alpha.1 — SP-API has 30+ product sections and this package covers the commerce-relevant subset (orders, listings, catalog, inventory, reports, finances, shipping, notifications). Endpoint paths and auth flow are implemented to the published spec; tool contracts should be integration-tested against real seller tokens before production use. The LWA refresh flow and x-amz-access-token header usage are confirmed against current SP-API docs.
