PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Online shops & payments
  • You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http valo-ia https://api.valotcg.com/mcp --header 'Authorization: Bearer {api_key}'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "valo-ia": {
      "url": "https://api.valotcg.com/mcp",
      "headers": {
        "Authorization": "Bearer {api_key}"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Common questions

Is Valo.IA (ValoTCG) safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 5 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spree Commerce: open-source B2B and marketplace ecommerce, Stripe MCP, MCP Cn Commerce

Valo.IA — MCP server for trading card prices

Ask your AI agent what any trading card is worth, and get a sourced, dated answer. Valo.IA is the hosted MCP server behind ValoTCG: 540,000+ card references across 14 games, with the real European price (Cardmarket in EUR), the US market price, what the card actually sold for on eBay, graded sales and PSA populations, sealed products and 365 days of history. One line of config, one API key, and your agent prices a collection, a shop inventory or a single pull like a market analyst.

Games covered: Pokémon · One Piece Card Game · Disney Lorcana · Yu-Gi-Oh! · Magic: The Gathering · Dragon Ball Super Card Game (Masters) · Dragon Ball Super Card Game Fusion World · Union Arena · Riftbound: League of Legends TCG · Cyberpunk Trading Card Game · Naruto Mythos TCG · Flesh and Blood · Gundam Card Game · Star Wars: Unlimited. Cards in English, French, Japanese and Chinese where the game prints them; the live coverage per source is at https://valotcg.com/developers/coverage.

Why agents like it

  • Every price says where it comes from, in which currency and on which day. No blended figure, no silent conversion, and status: "missing" instead of a guess when a source has nothing.
  • Graded and raw in the same call: eBay medians for PSA 9 and PSA 10 over 30 and 90 days next to the raw price, plus PSA and CCC populations by grade, to decide whether a card is worth grading.
  • Ready-made answers: price_summary returns a recommended price with its reliability and recent change, top_movers and top_priced rank a whole set, compare_prices lines up ten cards side by side.
  • Built for tooling: 16 read-only, idempotent tools, credit metering in the response, errors never billed, free Sandbox key to try.

This repository holds the public metadata of the server (server.json), setup instructions and examples. The server itself runs on ValoTCG's infrastructure; nothing needs to be installed or built from here.

Quick start

  1. Create a free Sandbox key at https://valotcg.com/developers/account (no credit card). Keys look like vd_test_… (Sandbox) or vd_live_… (paid plans).
  2. Add the server to your client.

Claude Code

claude mcp add --transport http valotcg https://api.valotcg.com/mcp \

--header "Authorization: Bearer $VALO_DATA_API_KEY"

Cursor, VS Code, Windsurf and other JSON-configured clients

{

"mcpServers": { "valotcg": { "type": "streamable-http", "url": "https://api.valotcg.com/mcp", "headers": { "Authorization": "Bearer vd_live_…" } } } }

  1. Ask your agent something like *"What is the current Cardmarket price of Charizard ex 199/165 from 151, French print?"* — it will call identify_card then get_card_prices or price_summary.

Tools

All 16 tools are read-only and idempotent. Each call is metered in Valo.Data credits (the credit cost is documented per tool in tools/list); an error is never billed.

ToolWhat it does
list_gamesThe 14 games listed above, their card languages and per-source coverage. Free.
list_editionsSets and expansions of a game, searchable by name or set code.
search_cardsSearch cards by name (FR/EN), number, edition, language or rarity.
get_cardOne card sheet: name, number, rarity, image, Cardmarket and US market ids.
get_card_pricesCurrent prices of a card per source, each dated; optional graded medians and PSA/CCC populations.
get_cards_batchPrices for up to 100 cards or sealed products in one call.
get_price_historyDaily history of one source for a card, up to 365 days, one point per observed day.
search_sealedSearch sealed products (boosters, displays, ETBs, boxes).
get_sealed_pricesCurrent prices of a sealed product per source.
identify_cardFind a card from free text such as "dracaufeu 199 151 fr".
price_summaryRecommended price, reliability and recent changes of a card or sealed product.
compare_pricesPrice summaries of up to 10 cards and sealed products side by side.
top_moversLargest price rises or falls of a game or an edition over 7, 30 or 90 days.
top_pricedMost valuable cards or sealed products of a game, an edition or a language.
edition_overviewChase cards, sealed products and price coverage of an edition.
scan_cardRecognise a card from a photo and return its Valo.Data ids (keys with the Vision scope only).

A quote that does not exist comes back with status: "missing" and a null amount, never an invented figure. Every price carries its source, currency and observation date; nothing is converted between currencies.

Behaviour and limits

  • initialize and tools/list answer without a key, so directories and clients can inspect the server. A tools/call without a valid key returns a tool error (invalid_api_key, not billed) pointing to the key page.
  • GET and DELETE on /mcp return 405: the server is stateless, without SSE streams or sessions.
  • Coverage differs by game; the live matrix is at https://valotcg.com/developers/coverage.
  • The Sandbox key is for prototyping and non-commercial use; paid plans add the commercial licence. Prices are net, VAT not applicable (art. 293 B of the French tax code). Plans: https://valotcg.com/developers/pricing.
