Transport: Streamable HTTP
Runtime: Web executable
Trust: Verified
Published: Oct 31, 2026

Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to usefulapi.io, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Hosted read-only MCP access to Stamped Loyalty 2.0 shop data: customers, products, orders, rewards and points activity.

What you can do: List, fetch and look up customers by id, email or platform id, including points and VIP tier summaries
List, fetch and look up catalog products by id or platform id
List, fetch and look up orders, including line items, discounts and dates
Read loyalty rewards reports with coupon codes masked, and the points activity ledger
Check monthly tool-call usage, request a missing feature, and upgrade or cancel the paid plan
When to use it: Useful when you want an assistant to answer questions about a Stamped loyalty shop — top points balances, the order behind a platform order id, recent earned or redeemed rewards — without building your own API integration.
Requirements: Remote MCP endpoint added by URL only; sign-in happens through OAuth with your Stamped credentials, so no API key or Authorization header goes in the client config. Only API-enabled Loyalty 2.0 shops are supported; legacy V2 reviews and review-only accounts are not. A free tier allows 50 tool calls per month.

Before you install

Customer contacts, addresses, orders and loyalty records requested through tools reach your AI client and its LLM provider. Paid plans cost money (Pro $9/month or $90/year, Pro+ $39/month or $390/year) and upgrade returns a Stripe Checkout link; cancellation runs to the end of the paid period with no refund. Tools are read-only, but usage and billing follow the shop ID, and access is stopped by revoking the dedicated key in Stamped.

Installation

In SourceWeft

Open Stamped MCP by usefulapi in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Fstamped/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

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.

Cursor and other clients: add the URL as a remote MCP server:

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.
