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.
match_merchant_accountUse when a merchant asks whether a high-risk merchant account review may fit their business. Inputs are the niche, monthly processing volume, country or entity, the current processor if any, and what happened (for example a shutdown, a limitation, a fund hold, or a new business).
build_shutdown_checklistUse when a merchant asks what to do after a Stripe, PayPal, or Shopify Payments shutdown, limitation, account review, or fund hold. Returns a practical checklist: what to save, how to answer the processor, how reserves and holds work in general, how to keep legitimate sales from
check_dispute_ratioUse when a merchant gives a monthly transaction count and dispute count, or pastes a short summary of those figures, and wants the dispute ratio. Computes disputes divided by transactions, explains how that simple ratio differs from Visa VAMP and Mastercard ECM, and summarizes pu

Common questions
Is RetryHub 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 (1.2.0) 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?
