Verdicts

BigCommerce API + MCP

Published rate limits per plan, with X-Rate-Limit-Time-Reset-Ms on every 429. Storefront MCP is beta, switched on per store, has no back-office tools and documents no tool annotations.

Elastic Path API + MCP

Cart, promotion code, checkout and order endpoints cover the whole test flow. MCP server exposes 95 tools with full CRUD, no read-only mode and no public source or licence.

Before you call either

BigCommerce API + MCP

  1. Give the agent a store-level API account with only the scopes the task needs, and delete it when done
  2. On a 429, wait X-Rate-Limit-Time-Reset-Ms before retrying
  3. Expect up to 10 minutes after a store owner enables the MCP before the URL answers
  4. The MCP stops at a checkout URL. Payment happens in the shopper's browser
  5. Point a coding agent at the docs MCP at https://docs.bigcommerce.com/_mcp/server

Elastic Path API + MCP

  1. Use a client_credentials token server-side only. It has full CRUD on the store
  2. Pick the base URL for the store's region (useast or euwest), or every call returns 401
  3. Loading the MCP server costs 95 tool definitions, so enable it only for agents that need the back office
  4. On a 429, wait a few seconds and retry. No Retry-After header is sent
  5. Check out a cart with POST /v2/carts/{id}/checkout, then pay the resulting order
