What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • lookup_bin

  • lookup_issuer

  • lookup_mcc

    Merchant category code (MCC) lookup. Pass a 4-digit MCC for its full definition (category group, high-risk flag, Visa and Mastercard definitions), or describe a business (for example "grocery store" or "software") to find the matching MCC.

  • lookup_decline_code

    Explain why a card payment was declined or failed. Accepts a decline code, response code, refusal reason or error message (for example "51", "05", "do_not_honor" or "insufficient funds") from card networks and processors such as Visa, Mastercard, Stripe and Adyen. Optionally narr

Common questions

Is SmartRetry Payment Tools safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 3 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?
