Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://stamped.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http stamped https://stamped.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "stamped": {
      "url": "https://stamped.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Stamped credentials.

Account eligibility and data

This initial release supports API-enabled Loyalty 2.0 shops. Legacy V2 reviews and review-only accounts are unavailable. No public key is needed. Customer contacts, addresses, orders and loyalty records requested through tools reach your chosen AI client and its LLM provider; API keys do not. Coupon codes are masked. No points adjustments, redemption, review publishing or other merchant writes are exposed.

Revoke the dedicated key in Stamped to stop access. Usage and billing identity follow the shop ID. Requests are never automatically retried. Independent integration; no Stamped approval or endorsement claimed.
