Overview

AI-generated overview

A remote MCP server for searching, comparing and estimating rewards across US credit cards, with verified fees, bonuses and eligibility data.

What you can do
Search and filter the US credit-card dataset by product type, rewards currency, issuer, fees, signup bonus, credit band or category, defaulting to issuer-verified cards only. Retrieve full detail for a single card, including earn rates, credits, eligibility, sources and last-verified date. Compare two or more cards side by side on fees, foreign-transaction fee, signup bonus, earn rates, credits and eligibility. Estimate net rewards value from an annual spending profile and rank cards. Check which cards a given credit band and income would typically qualify for, including issuer application rules. Return apply links for cards.
When to use it
Useful when someone is choosing a US credit card and wants to filter, compare or estimate first-year value from a spending profile, or check likely eligibility before applying.
Requirements
A remote streamable HTTP endpoint; no local runtime, account, API key or environment variable is declared. Network access to the endpoint is required.
Before you install
Apply links are always creditcards.best tracked redirects that record a referral, and the raw issuer URL is never returned, so the operator may earn commission. Card data and eligibility results are informational and may not reflect current issuer terms; verify with the issuer before applying.

Installation

In SourceWeft

  1. Open creditcards.best in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/best.creditcards%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

search_cards

Search credit cards

Filter the US credit-card dataset by product type, rewards currency (program name or kind), issuer, annual fee, foreign-transaction fee, signup-bonus value, credit band, or curated category. Searches ONLY issuer-verified cards by default, because unverified stubs carry null for most filterable fields and a null is not a zero. Set verified:false for the stubs, or verified:null to search everything knowingly. Returns at most 25 summaries unless you raise `limit`; `total` is the full match count and `truncated` says whether you are seeing all of it. Rankings reflect fit, not placement.

get_card

Get one card

Full detail for a single card by id (slug), including earn rates, credits, eligibility, sources and lastVerified. The apply link is our tracked redirect, not the issuer URL.

Parametersidrequired

estimate_rewards

Estimate annual rewards

Given an annual spending profile (USD per category, e.g. { dining: 6000, groceries: 8000, travel: 4000, other: 20000 }), estimate each card's net rewards value and rank them. Net value = rewards earned on spend + first-year signup bonus − annual fee. Statement credits are reported separately (max value if fully used), NOT folded into the headline, to avoid overstating premium 'coupon-book' cards. Returns a per-category breakdown and the assumptions used. All card facts come from the verified dataset; only point valuation is modeled.

ParameterslimitspendrequiredcardIdscreditBandincludeSignupBonus

check_eligibility

Check likely eligibility

Given a user's credit band (and optionally income), return cards they would typically qualify for, surfacing issuer application rules (e.g. Chase 5/24) and any income floor. Only cards that publish a credit requirement can be answered; cards with no published requirement are counted in `unknownCount`, never listed as qualifying. This is a likelihood signal from published guidance, not an approval guarantee.

ParameterscardIdsincomeUsdcreditBandrequired

compare_cards

Compare cards

Side-by-side detail for two or more cards by id: fees, foreign-transaction fee, signup bonus, earn rates, credits and eligibility. Apply links are tracked redirects.
