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

cards

get_set_cards

Use this when the user wants the most valuable cards in a specific set or a priced checklist of a set. Requires a set id from list_sets. Returns raw and PSA 10 USD prices per card. Do not use for a single named card; use search_cards instead.

search_cards

Use this first when the user names a trading card and wants its value, price, or whether to grade it. Searches 1.5M+ Pokémon, Magic, Yu-Gi-Oh!, One Piece, Lorcana, sports (baseball, basketball, football, hockey, soccer, wrestling, UFC and more) and entertainment cards by name, set, number and year, returning ungraded and PSA 10 market prices in USD from real sold listings. Returns card ids for get_card_prices, grading_roi and get_price_history. Do not use for sealed product, for cards you already have an id for, or for price prediction.

best

best_cards_to_grade

Use this when the user asks which cards in a game, sport or set have the biggest payoff from grading. Ranks priced cards by expected net profit at a 50% gem rate (half PSA 10, half PSA 9, minus raw and the fee), requiring both PSA 9 and PSA 10 prices so thin-market outliers are excluded. Returns card ids for grading_roi. Do not use for a single named card.

card

get_card_prices

Use this when the user wants the full current value of a specific card: ungraded prices by condition (NM/LP/MP/HP) and graded prices for every company and grade on record (PSA, CGC, BGS, SGC, TAG). Requires a card id from search_cards. Prices are USD market values from real sold listings, refreshed daily. Do not use to search by name.

grading

grading_roi

Use this when the user asks whether a card is worth grading, submitting to PSA/CGC/BGS/SGC/TAG, or what a PSA 10 adds. Returns raw vs PSA 9 vs PSA 10 market prices, the gem premium, net profit after grading fees per outcome, expected value by gem probability, the break-even gem rate, which company pays most, and a plain-language verdict. Requires a card id from search_cards. It does not assess the condition of the user's copy.

liquid

liquid_movers

Use this when the user wants cards that are both rising in price and easy to sell: recent gainers filtered to cards with at least 25 recorded sales a year and a raw price of at least $5, across all games and sports. Better than trending_cards for flipping or selling decisions. Do not use for a single named card.

price

get_price_history

Use this when the user asks how a card's price has changed over weeks or months, or wants a trend for the raw or a PSA-graded series. Returns dated USD market values for the last 7 to 180 days. Requires a card id from search_cards. Do not use for forecasts.

sets

list_sets

Use this to find the set id for a game or sport (e.g. "Evolving Skies", "2019 Panini Prizm") before calling get_set_cards, or when the user asks which sets exist. Newest first. Do not use to price a single card.

trending

trending_cards

Use this when the user asks which cards are rising, hot, spiking, crashing or trending, in one game or across all games. Returns the biggest 30-day gainers (or drops) with the percentage change, measured on the PSA 10 price where the card has one and on the raw price otherwise; moves over 300% are excluded as bad data. Do not use for a single named card or for long-term history.

Is Midpoint Card Prices working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 238 ms. The bar chart above shows every period we have measured.

How do I connect Midpoint Card Prices?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Midpoint Card Prices need an API key?

No. Midpoint Card Prices completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Midpoint Card Prices?

It answers our handshake in 238 ms on average, which is faster than 59% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Midpoint Card Prices open source?

We cannot say either way: written in TypeScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
