Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to hobbycardindex.com, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Installation

In SourceWeft

Open HobbyCardIndex Card Prices in the dashboard and add it to a workspace.
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/com.hobbycardindex%2Fcard-prices/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

HobbyCardIndex API: sports card and Pokémon card prices, sold sales, cert lookup and card recognition

Examples, JavaScript and Python SDKs, and MCP setup for the HobbyCardIndex Data API.

The HobbyCardIndex Data API returns raw and graded prices, based on real sold prices, for a 16M+ card catalog across 25+ categories: baseball, basketball, football, hockey, soccer, Pokemon, Magic: The Gathering, Yu-Gi-Oh, One Piece and more. It also identifies a card from a photo, looks up PSA, BGS, CGC and SGC certs, and returns sold sales, price history, pop reports and market movers.

Used by card apps and marketplaces, graders, dealers and shop software, and AI agents (through the MCP server).

Plans

For apps and websites whose users see the data: Lite $99, Growth Lite $249, Growth $499 and Platform $1,500 a month, billed monthly, cancel any time. A free setup month is available by application at https://hobbycardindex.com/developers.

Keeping your own copy of every price? Add the daily price files ($450 a month on Growth Lite or Growth): current prices for every card in a category as one download a day, instead of paging through search.

Not sure which size fits? GET https://hobbycardindex.com/api/v1/agent/plans?use_case=<id> recommends one for display_prices, copy_all_prices, photo_scans, sold_sales, certs_and_pop or own_use, and an agent can buy it there with no account (POST /api/v1/agent/checkout; the buyer pays on Stripe's page). Your own business's internal use is covered by the Enterprise plan ($49.99 a month). Full terms: https://hobbycardindex.com/terms/ section 8.

MCP (AI assistants)

AI assistants that speak the Model Context Protocol connect to https://hobbycardindex.com/api/v1/mcp (Streamable HTTP, JSON responses, no session) with the same key as the X-API-Key header. Tools: search_cards, get_card_prices, and, without a key, list_plans (pass use_case for a recommendation) and start_checkout. Client configs for Claude Desktop, Claude Code, Cursor and VS Code are in examples/mcp/.

Tools

search_cards

Search card prices

Find a sports or trading card and its current sold price. Describe the card the way a collector would, for example "1989 Upper Deck Ken Griffey Jr 1", "2018 Topps Update Acuna US250" or "Charizard Base Set". Returns up to 5 matching cards with the raw (ungraded) and PSA 10 price, a card_id, and the link to the card page. Use get_card_prices for every grade of one card. Needs a HobbyCardIndex API key.

Parameterslimitqueryrequiredcategory

get_card_prices

Card prices by grade

Current sold prices for one card at every grade: raw (ungraded), PSA 7, PSA 8, PSA 9, PSA 10, BGS 9.5, CGC 10 and SGC 10, in US dollars, with the link to the card page for recent sales and price history. Take the card_id from search_cards. Needs a HobbyCardIndex API key.

Parameterscard_idrequired

list_plans

Commercial API plans and prices

The HobbyCardIndex plans a user can buy right now: the Commercial API sizes (requests, photo scans, sold-sale lookups, cert lookups) and the app plans Pro, Dealer and Enterprise (scans a month, dealer tools, API key on Enterprise), with monthly prices in US dollars, the terms and how to buy. Pass use_case to get the size and add-ons that fit what the user wants to do. Works without an API key.

Parametersuse_case

start_checkout

Buy a Commercial API plan

Start buying a Commercial API plan for the user. Returns a Stripe checkout_url where the user pays by card (HobbyCardIndex never sees the card) and a status_url that returns the API key once, after payment. Only call this after the user has picked a plan from list_plans and agreed to the terms (accept_terms: true). Use the user's own email: the receipt and the account sign-in go there. Works without an API key.

100% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
