# Share-A-Cart

> Share-A-Cart is a shopping cart sharing platform that allows users to create, share, and receive shopping carts from hundreds of online retailers.

Share-A-Cart and its browser extensions help users collaborate and save time while shopping by creating shareable cart links. Add items to your cart and share the full list with family, friends, or coworkers — they can load your cart with a single click.

## Developer & MCP Documentation

> Share-A-Cart exposes a Model Context Protocol (MCP) server so AI assistants and agents can search retailers, build carts, save shareable cart links, and surface deals on the user's behalf.

The MCP server uses streamable HTTP and is available at `https://share-a-cart.com/mcp`. Connecting requires signing in with a free Share-A-Cart account via OAuth — MCP clients discover and handle the flow automatically (a browser opens to sign in and approve on first connect). Connect it to any MCP-compatible client by adding an HTTP server entry pointing at that URL, for example:

```json
{
  "mcpServers": {
    "share-a-cart": {
      "url": "https://share-a-cart.com/mcp"
    }
  }
}
```

Clients without native HTTP support can connect via the `mcp-remote` bridge. See the connecting guide below for client-specific instructions (Claude, Cursor, VS Code, and others).

A companion **agent skill** packages the shopping workflow on top of the MCP. Install it as a Claude Code plugin (`/plugin marketplace add share-a-cart/skills`) or with the `skills` CLI (`npx skills add share-a-cart/skills --skill share-a-cart`); the skill works with or without the MCP connected.
