OpenAI plugin

The Littleworks MCP connection and agent guidance in one package.

What the plugin includes

  • The shared Littleworks MCP server: https://littleworks.app/mcp.
  • A skill explaining when to use Littleworks, how to inspect the connected store, and how to build and test works.
  • OAuth approval inside Shopify, with no manual API keys or Shopify credentials.

Connect your client

Use the connection guide to set up Littleworks in ChatGPT, Work, or Codex. Setup depends on your client and workspace settings. Each client authorizes its own connection; configuring local Codex does not connect ChatGPT web.

Store access

Installation makes the connection available; OAuth grants access. Choose your store during authorization and approve in Shopify. The connection is limited to that store. Installing the plugin does not create a work or authorize a build or change.
