Ask Lolumen from Claude.Cards, bans and the meta, in any chat.

Lolumen runs an MCP server. Add it to Claude once, and Claude can look things up on Lolumen while you talk: whether a card is in Standard, what a deck code holds, what's banned, how classes are doing. It reads only what the site shows everyone, and needs no sign-in.

Connector address

https://www.lolumen.com/mcp
  1. Open Claude's settings. On claude.ai or in the Claude app, go to Settings, then Connectors.
  2. Add a custom connector. Name it Lolumen and paste the address above. Leave the advanced settings empty: there's nothing to sign in to.
  3. Turn it on in a chat. Open the tools menu under the message box and switch Lolumen on, then ask away.

In Claude Code: claude mcp add --transport http lolumen https://www.lolumen.com/mcp

What it can answer

Hearthstone cards

  • Search Hearthstone cardsSearch every collectible Hearthstone card by name or card text, and filter by class, mana cost, type, rarity, tribe or spell school, expansion and format (standard or wild). Returns matching cards with their text, set and where they can be played, plus a link to each card on Lolumen.
  • Get a Hearthstone cardEverything about one Hearthstone card by name or card id: cost, stats, text, class, rarity, expansion and year, crafting cost, flavor, artist, whether it is legal in Standard and Wild (with any ban), its other printings, a picture and its Lolumen page.
  • Is a card in Standard?Answers whether Hearthstone cards can be played in Standard and in Wild right now, counting every printing (a Core reprint makes a card Standard) and current bans. Give up to 30 card names or ids at once.
  • The Standard formatThe current Standard year: which expansions and sets are in Standard, when the next rotation is expected, and how many cards each set has.
  • Banned cardsEvery Hearthstone card currently banned in Standard or Wild, with the date the ban took effect, whether it is temporary, and the announcement.
  • Hearthstone setsEvery Hearthstone card set and expansion, newest first, with its release year, card count and whether it is in Standard.

Hearthstone decks and meta

  • Read a deck codeReads a Hearthstone deck code (or a whole pasted deck list with its code): the class, format, every card with its count and cost, the mana curve and the dust to craft it, and whether every card is legal in the deck’s format today (listing rotated or banned cards).
  • Class win ratesEach Hearthstone class’s win rate and share of games, from the ranked games players track on Lolumen and chose to share. Each rate comes with a 95% range and the number of games behind it; small samples are marked early. Class-against-class matchups are a Premium feature on the site and are not included.
  • What players buildWhat Hearthstone players are building, from the decks they share publicly on Lolumen over the last 60 days: each class’s share of decks and average dust, and the most-played cards with how often they are included.
  • Community decksHearthstone decks players have shared publicly on Lolumen, newest or most liked first, filtered by class and format, with each deck’s dust, likes and page.

Daily games

  • Today's daily gamesToday's Lolumen daily guessing games for Hearthstone and League of Legends: what each one asks, today's puzzle number, when the next puzzles start, and where to play. It never reveals answers.
  • Daily game leaderboardThe public leaderboard for one Lolumen daily game: today's fastest solvers by guesses, or the longest current streaks. Only players who chose to appear on leaderboards are listed.

Defaults to the latest patch against the one before. Some changes live only in tooltips and won’t show here; Riot’s notes are the full record.

What it never shares

The connector can't see anyone's account, tracked games, private decks or settings, and it never gives away a daily puzzle's answer. Class win rates and deck trends come only from games and decks players chose to share, and leaderboards list only people who chose to appear on them. Read the docs
