Stampcard — digital stamp cards for small shops, no app for the customer is an MCP server with 5 tools an agent can call, among them create_program, get_card, program_stats. It answers at https://stampcard.rowb.app/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 4 of 4 times since 24 September 2026; the last check, on 7 November 2026, succeeded.
Create a shop program, hand customers a browser stamp card by QR poster, stamp it from a phone.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
create_program | Create or update the shop program: shop name, reward text, stamps required before a reward. Returns the program and its join URL (the poster target). Inputs: shop, reward, stamps_required |
get_card | Read one customer card: how many stamps, what the reward is, whether it is ready to redeem. Inputs: code, token |
program_stats | Program plus this month stamp usage and quota, so a shop can tell how close it is to the free limit. |
redeem | Redeem the reward on a card that has reached its required stamps. Resets the stamp count and increments the rewards-earned counter. Inputs: code, token |
stamp | Add one stamp to a customer card. Identify the card by its 8-character code (from the customer page) or by its token. One stamp per card per day unless allow_multiple is true. Inputs: code, token, allow_multiple |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://stampcard.rowb.app/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: app.rowb.stampcard. Endpoint host: stampcard.rowb.app. ARD identifier: urn:air:app.rowb.stampcard:mcp:cards.
First indexed 24 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
