nanocart-mcp

Official NanoCart MCP server — run your store from any MCP-capable AI agent (Claude Code, Claude Desktop, Cursor, Codex, and friends). List and update products (with variants and images), manage orders, coupons, categories, subscribers and settings, and pull sales reports — by asking.

39 tools. Reads are marked read-only; destructive tools (archive product, delete coupon) are annotated so your agent asks before acting. Refunds, billing changes, and API-key management are deliberately NOT exposed — do those in your dashboard.

Credentials

From your dashboard: Settings → API Keys (sc_live_..., keep secret) and Settings → Store Information (your store ID). The key grants full admin access to your store — treat it like a password.

Option A — Local (recommended)

Claude Code:

claude mcp add nanocart --env NANOCART_API_KEY=sc_live_... --env NANOCART_STORE_ID=your-store-id -- npx -y nanocart-mcp

Any client that speaks stdio MCP (JSON config style):

{
  "mcpServers": {
    "nanocart": {
      "command": "npx",
      "args": ["-y", "nanocart-mcp"],
      "env": {
        "NANOCART_API_KEY": "sc_live_...",
        "NANOCART_STORE_ID": "your-store-id"
      }
    }
  }
}

Option B — Hosted (no install)

Endpoint: https://mcp.nanocart.io/mcp?store=your-store-id with header Authorization: Bearer sc_live_... (Streamable HTTP).

Claude Code:

claude mcp add nanocart --transport http "https://mcp.nanocart.io/mcp?store=your-store-id" --header "Authorization: Bearer sc_live_..."

Note: web clients that only support OAuth-based custom connectors (e.g. claude.ai's connector UI) can't send API-key headers yet — use Option A there.

Example prompts

• "List my draft products and publish the ones with images"

• "Create a SUMMER20 coupon — 20% off, min order $50, expires end of August"

• "What did I sell last week? Any orders I still need to ship?"

• "Mark order NCT-1042 shipped with tracking 9400 1000 0000 0000 0000 00"

• "Upload the photos in ./shots and create products from them at $24 each"

Safety

• Secrets are redacted from every response; your key is never echoed or logged.

• Destructive tools carry MCP destructiveHint annotations — well-behaved clients prompt before running them.

• Prices are explicit price_cents integers (no dollars/cents ambiguity).
