MCP server

What it is
Storefront MCP has a unique URL per storefront (control panel: Settings > API and MCP), so no fixed server_url. A separate Docs-only MCP exists at https://docs.bigcommerce.com/_mcp/server (search only, no store access)

How to automate BigCommerce

API and webhooks

BigCommerce documents REST management and storefront APIs, GraphQL storefront, admin and account APIs, and a payments API. You can download OpenAPI specs. Check the webhook options in the docs for events such as new orders.

Automation idea: when an order is placed, send it to your ERP or accounting tool and update stock levels.

MCP server

BigCommerce hosts an MCP server in beta. Store owners enable it in the control panel and get a unique server URL per storefront. B2C and B2B tool sets let an AI agent search products, manage a cart and hand off to checkout in natural language.

Automation idea: connect an assistant to your storefront and let it answer product questions with live catalogue data.

Native integrations

Helpdesk and email tools connect to BigCommerce directly. Gorgias puts customer chats and order data in one inbox, and Klaviyo can use store data for campaigns.

Automation idea: send an abandoned-cart email sequence from store data.
