No price between the free plan and a sales-quoted Enterprise contract.\n\n**Medusa API + MCP.** MIT core you can self-host, with Medusa Cloud running the same APIs and no GMV fee. The official MCP server is docs-only and limited to Cloud accounts.\n\n## Before you call either\n\n### Commerce Layer API + MCP\n\n1. Call `get_resource_schema` before any write. Preflight rejects bad filter shapes before they reach the API\n2. Give the agent an integration credential tied to a narrow role rather than an admin role\n3. On a 429, wait out the sliding window. No Retry-After is sent, and the IP stays blocked while the rate stays high\n4. Place an order by PATCHing it with `_place: true` once line items, addresses, shipping and payment are set\n5. Move reads of `mode`, `organization_id` and `trace_id` to root-level meta before 5 October 2026\n\n### Medusa API + MCP\n\n1. Send x-publishable-api-key on every /store call. It decides which sales channels and products the agent sees\n2. Ask for only the fields you need with `fields`. Store routes reject relations nested more than three deep since 2.20.0\n3. Read the store's regions before creating a cart, since prices and shipping options depend on region\n4. Place the order with POST /store/carts/{id}/complete after shipping and payment sessions are set\n5. Read the release notes before upgrading a minor version. Breaking changes land there\n\n## Other comparisons with Commerce Layer API + MCP or Medusa API + MCP\n\n- [BigCommerce API + MCP vs Commerce Layer API + MCP](https://www.anchorterminal.com/compare/bigcommerce-vs-commerce-layer.md)\n- [BigCommerce API + MCP vs Medusa API + MCP](https://www.anchorterminal.com/compare/bigcommerce-vs-medusa.md)\n- [Commerce Layer API + MCP vs Elastic Path API + MCP](https://www.anchorterminal.com/compare/commerce-layer-vs-elastic-path.md)\n- [Commerce Layer API + MCP vs Saleor API + MCP](https://www.anchorterminal.com/compare/commerce-layer-vs-saleor.md)\n- [Commerce Layer API + MCP vs Shopify API + MCP](https://www.anchorterminal.com/compare/commerce-layer-vs-shopify.md)\n- [Commerce Layer API + MCP vs Snipcart API + MCP](https://www.anchorterminal.com/compare/commerce-layer-vs-snipcart.md)\n- [Commerce Layer API + MCP vs Swell](https://www.anchorterminal.com/compare/commerce-layer-vs-swell.md)\n- [Commerce Layer API + MCP vs Vendure](https://www.anchorterminal.com/compare/commerce-layer-vs-vendure.md)\n- [Commerce Layer API + MCP vs WooCommerce API + MCP](https://www.anchorterminal.com/compare/commerce-layer-vs-woocommerce.md)\n- [Elastic Path API + MCP vs Medusa API + MCP](https://www.anchorterminal.com/compare/elastic-path-vs-medusa.md)\n- [Medusa API + MCP vs Saleor API + MCP](https://www.anchorterminal.com/compare/medusa-vs-saleor.md)\n- [Medusa API + MCP vs Shopify API + MCP](https://www.anchorterminal.com/compare/medusa-vs-shopify.md)\n- [Medusa API + MCP vs Snipcart API + MCP](https://www.anchorterminal.com/compare/medusa-vs-snipcart.md)\n- [Medusa API + MCP vs Swell](https://www.anchorterminal.com/compare/medusa-vs-swell.md)\n- [Medusa API + MCP vs Vendure](https://www.anchorterminal.com/compare/medusa-vs-vendure.md)\n- [Medusa API + MCP vs WooCommerce API + MCP](https://www.anchorterminal.com/compare/medusa-vs-woocommerce.md)\n",
