Overview

AI-generated overview

Lets an assistant set up a shop loyalty stamp program, add stamps to customer cards, check cards, redeem rewards and view usage stats.

What you can do
  • Create or update the shop program (name, reward text, stamps needed) and get its join URL for the poster
  • Add a stamp to a customer card, identified by its 8-character code or token
  • Read a single card: stamp count, reward, and whether it is ready to redeem
  • Redeem a reward on a qualifying card, resetting stamps and incrementing rewards earned
  • Check program details plus this month's stamp usage and quota
When to use it
Useful for a small shop that wants an assistant to run a browser-based digital stamp card: setting up the program, stamping customers from a phone, and redeeming rewards without a customer app.
Requirements
Remote MCP endpoint over streamable HTTP. Calling the tools needs a Bearer shop API key from the provider's signup page, sent in the Authorization header. No packages or environment variables are declared.
Before you install
The Authorization header carries a shop API key, so keep it private. Stamping and redeeming change customer card data: redeem resets the stamp count and increments the rewards-earned counter, and stamping is limited to one per card per day unless allow_multiple is set. Usage counts against a free-tier quota.

Installation

In SourceWeft

  1. Open Stampcard — digital stamp cards for small shops, no app for the customer in the dashboard and add it to a workspace.
  2. 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/app.rowb.stampcard%2Fcards/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
