## Verdicts

**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.

**WooCommerce API + MCP.** Free GPL software with no platform fee or revenue share. Uptime, speed and security depend on each store's host and plugins. No vendor status page.

## Before you call either

### Medusa API + MCP

1. Send x-publishable-api-key on every /store call. It decides which sales channels and products the agent sees
2. Ask for only the fields you need with `fields`. Store routes reject relations nested more than three deep since 2.20.0
3. Read the store's regions before creating a cart, since prices and shipping options depend on region
4. Place the order with POST /store/carts/{id}/complete after shipping and payment sessions are set
5. Read the release notes before upgrading a minor version. Breaking changes land there

### WooCommerce API + MCP

1. Create a REST key with read permission only for reporting tasks, and send it in the Authorization header, never the URL
2. Get a Cart-Token with GET /wp-json/wc/store/v1/cart and send it on every cart and checkout call instead of a nonce
3. Add `_fields=id,name,price` to REST calls to cut response size
4. Page with per_page up to 100 and stop at X-WP-TotalPages
5. Product delete only trashes unless you pass force true, so check the trash before assuming it's gone
