RightCard — Claude Code MCP server: what it does, how to install
Determines the highest-earning credit card for any merchant using verified reward terms without requiring bank credentials or user accounts.
claude mcp add --transport http mcp https://mcp.rightcard.ai/mcpWhat RightCard does
The server acts as a card recommendation oracle for coding agents. You provide card identifiers along with a retailer name, and it evaluates current reward tiers, rotating quarterly bonuses, and merchant category code caveats. Calculations use cash back values by default, though passing valuation: "points" switches the math to conservative travel point valuations.
Tooling includes five methods: best_card for direct payout comparisons, lookup_merchant to inspect store category classifications, search_cards to look up supported products, plus card and rotating_calendar for reward schedule details. The underlying engine matches the logic of the iOS application and verifies calculations against 3,100+ reference fixtures.
Targeted user-specific merchant credits are omitted by design because personal cardholder deals remain strictly on mobile devices. You can integrate via the remote streamable HTTP endpoint at https://mcp.rightcard.ai/mcp or run stdio locally using npx rightcard-mcp.
What it helps with
- identify the card earning the highest reward at a specific retailer
- check merchant category coding and MCC exclusions before purchasing
- track current and upcoming quarterly bonus rotation schedules
- look up verified card identifiers across supported issuers
Example prompts for the agent
- I have Amex Gold, Freedom Flex, and Citi Double Cash. Which card should I swipe at Costco?
- Look up how merchant coding works for Target using RightCard
- Show active rotating category benefits for my Chase Freedom Flex card
