Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

best
best_card
Which of the given cards earns the most at a store (merchant) or for a spend category, today. Returns the card, the honest rate, why, and caveats (merchant-code traps, activation, ties). Base rates + rotating bonuses + built-in card benefits only; a user's personal bank offers live on their phone and are not consulted here.
card
card
Everything RightCard knows about one card: rates by category, base rate, currency, annual fee, verification status, live rotating windows, and the choose-your-category spec if it has one.
cards
search_cards
Search RightCard's catalog by card or issuer name to get the ids to pass into best_card. Verified cards first; unverified cards are flagged, never hidden.
lookup
lookup_merchant
The store's reward category as RightCard's directory files it, its merchant type, and the merchant-code caveat when a category bonus usually will not post there (superstores like Walmart/Target, warehouse clubs like Costco/Sam's). Same ranking the app uses.
rotating
rotating_calendar
Live and upcoming rotating-category windows (Freedom Flex, Discover it, Citi Dividend…) and permanent merchant benefits, from the same verified data as the app. Optionally filter by card id.

RightCard — questions

Answers built from our own checks of this server.

What can RightCard do?
It exposes 5 tools, read directly from the server on our last check. Among them: best_card, card, lookup_merchant, rotating_calendar, search_cards. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is RightCard working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 126 ms. The bar chart above shows every period we have measured.
How do I connect RightCard?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does RightCard need an API key?
No. RightCard completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is RightCard?
It answers our handshake in 126 ms on average, which is faster than 80% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use RightCard?
The npm package rightcard-mcp was installed 843 times in the last week. Week over week that is +22%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is RightCard open source?
Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
