Extend

APIs, MCPs and connectors to make it your own.

APIs for custom storefronts and back-office automation, MCP servers for AI-native workflows, automations and pre-built connectors for third-party platforms.

Programmatic access, front to back. RESTful APIs for storefront and admin use cases: build custom checkout flows or sync Supercycle data with your internal stack.

Admin API

Full programmatic access to products, inventory, rentals, returns, charges and custom fields: RESTful endpoints with API key authentication.

Storefront API

Build bespoke storefronts with real-time availability, pricing and rental intent while Supercycle handles cycle creation and payment orchestration.

MCP servers for AI-native workflows. Connect Claude, ChatGPT or any MCP client to Supercycle, for building integrations or running operations from natural language, or ask Sidekick inside Shopify admin.

Operators MCP

Connect your AI assistant to your Supercycle data and operate in natural language. Works with Claude, ChatGPT and any MCP client via OAuth.

Builders MCP

Give your AI tools direct, structured access to Supercycle's docs and API reference. Read-only, unauthenticated, and it plugs into any MCP-capable tool.

Shopify Sidekick

Supercycle ships native Sidekick extensions, so Shopify's own assistant can query your cycles, customers and returns, add a product to your Supercycle catalog, surface circular insights in Shopify Analytics and build Flow automations with Supercycle triggers.

Trigger workflows on any event. Supercycle plugs straight into Shopify Flow as our workflow engine, with pre-built connectors for the rest of your operational stack.

Shopify Flow

Drop Supercycle triggers and actions into Shopify Flow to react to rental events, returns and contract signatures alongside your existing automations.

Connectors

Templated connectors for platforms like Patchworks link 3PLs, ERPs and other systems in minutes, no code required.

Extend the data model. Capture business-specific data on items, cycles and consignors, calculate new values from it with Liquid, and bridge to your wider stack via Shopify metafields.

Custom and calculated fields

Add custom fields to items, cycles and consignors (sizing, fabric notes, internal references), or calculate read-only ones from a Liquid formula over system data: time to breakeven, has broken even, cycle yield. Surface any of them in admin views, workflows or the API.

Frequently asked questions.

What can I build with the Admin API?

The Admin API gives full programmatic access to products, inventory, rentals, returns, charges, custom fields and more. Use it for back-office integrations, automation layers, data sync with ERPs, or building custom internal tools.

What's the difference between the two MCP servers?

The Builders MCP gives AI tools read-only access to Supercycle documentation and API reference, useful when building integrations. The Operators MCP connects your AI assistant to your live Supercycle data so you can query and manage operations using natural language.

Do I need to write code for integrations?

Not always. Pre-built connectors for platforms like Patchworks enable no-code integrations with 3PLs, ERPs and other systems. Automations and Shopify Flow provide trigger-and-action workflows without code. The APIs are there when you need deeper customization.

Which AI assistants work with the Operators MCP?

The Operators MCP works with Claude, ChatGPT and any MCP-compatible client. It uses OAuth authentication with your Shopify account. Read tools are auto-approved; write tools request confirmation before making changes.

What can I add custom fields to?

Custom fields can be added to items, cycles and consignors to capture data specific to your business: sizing, fabric notes, condition specifics, internal references and more. Calculated fields sit alongside them and derive a read-only value from a Liquid formula over your custom fields and built-in system data, such as an item's time to breakeven. Use any of them in workflows, in reporting or via the API.

Can you customize Supercycle?

Yes. Supercycle is built to be flexible while staying easy to use. Because we leverage the full Shopify platform, you get all of Shopify's customization power: theme flexibility, APIs, metafields and the broader app ecosystem. On top of that, Supercycle provides its own extensible layer, including an Admin API and Storefront API for more complex or unique requirements.
