- check_deck_legalityValidate a decklist against a constructed format's rules (banned cards, deck size, copy limits, and in Commander the color-identity rule). Use this rather than recalling ban lists from memory: bans c…
- commander_staplesThe cards most commonly played with a given commander, from EDHREC's aggregate inclusion data: 691,958 commander-card pairings across 2,631 commanders. Returns each card's deck count, the share of th…
- deck_statsDeterministic statistical analysis of a decklist (any format): mana curve with creature split, card types, color pips vs mana sources, functional buckets (ramp/draw/removal/wipes/counters/recursion/p…
- find_combosDetect known combos in a decklist using Commander Spellbook's curated database — combos fully present, plus near-misses one card away (with that card's price). Pass `format` (and `commander` for Comm…
- find_synergiesGiven one or more cards the user ALREADY has, find cards that work with them. Seeded by example rather than by description: pass the cards, get partners. Use semantic_card_search instead to describe …
- get_cardFetch full detail for ONE card by exact name or id: oracle text, mana cost, type line, format legalities, and a brief summary of its printings. Use get_card_printings instead when the complete printi…
- get_card_imageFetch a card's image. The returned image content block IS the display — the client renders it directly; do not build custom HTML/widgets around the imageUrl, since sandboxed widget environments block…
- get_card_printingsList EVERY printing of a card (set, rarity, artist, finish, collector number). get_card already returns a short printings summary, so reach for this only when the full list is the point.
- get_card_rulingsFetch the OFFICIAL Wizards rulings for one card, with their dates. These are Wizards' own answers to the corner cases players argue about. Use this for any "how does this card actually work" question…
- get_ruleFetch a Comprehensive Rules entry and its lettered subrules by exact number (e.g. "601.2" returns 601.2 and 601.2a-i). Use after search_rules to read a rule's full context.
- my_collectionSummarize the user's imported collection: how many distinct cards, total copies, and where it was imported from. This is the SUMMARY only. Use search_my_collection to look up individual owned cards, …
- rate_deckAssess a Commander deck's official WotC bracket (1-5). Returns deterministic signals (Game Changers from WotC's curated list, mass land denial, tutors, fast mana, free interaction), a bracket FLOOR f…
- resolve_card_namesCheck whether card names are REAL, in bulk. Returns exact / not_found per name, with the canonical spelling and id for the ones that exist. Call this reflexively before presenting any decklist or car…
- search_cardsFind cards by NAME or by structured filters (colors, color identity, types, mana value, format legality, sets). Use when the query can be expressed as filters: "red instants under 3 mana", "legendary…
- search_my_collectionSearch only the cards the user OWNS, by name, colors, or type. Set notInDecks to surface owned cards not currently used in any of their decks (the "what is sitting idle in my binder" question). Use s…
- search_rulesSemantic search over the Magic Comprehensive Rules, glossary, and 84k card-specific rulings. Use for any rules/interaction question; answer FROM the returned chunks and cite rule numbers (e.g. 601.2a…
- semantic_card_searchVector search over card TEXT, for describing an effect that cannot be written as a filter: "cards that make a token when I attack", "punish opponents for drawing", "does what Rhystic Study does but c…
- upgrade_deckSuggest priced deck upgrades: cards to add (within an optional budget) and cards to cut. TWO-PHASE: first call WITHOUT `strategy` to get a deck analysis and instructions for deriving the deck's strat…
- what_can_i_buildGiven the user's imported card collection, rank the Commander decks they can most nearly build right now, with the most-played cards they are still missing. Answers "what should I sleeve up tonight" …
