RightCard is an MCP server with 5 tools an agent can call, among them best_card, card, lookup_merchant. It answers at https://mcp.rightcard.ai/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 10 of 10 times since 4 September 2026; the last check, on 17 October 2026, succeeded.
Which of your credit cards to use at any store, from verified bank data. No bank login.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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 benefit Inputs: wallet, merchant, category, valuation, on, chosen_categories |
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. Inputs: id |
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 rank Inputs: name |
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. Inputs: card_id |
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. Inputs: query, issuer, limit |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.rightcard.ai/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: ai.rightcard. Endpoint host: mcp.rightcard.ai. ARD identifier: urn:air:ai.rightcard:mcp:mcp.
First indexed 31 August 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.
