## Tools (as reported by the server, not verified)

- `check\_deck\_legality`: Validate 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 changed four times in 2026 alone, and a model's training cutoff makes stale ban data one of the most c
- `commander\_staples`: The 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 that commander's decks running it, and its synergy score. Synergy matters as much as popularity: a high
- `deck\_stats`: Deterministic statistical analysis of a decklist \(any format\): mana curve with creature split, card types, color pips vs mana sources, functional buckets \(ramp/draw/removal/wipes/counters/recursion/protection/tutors + bracket signals\) with typical Commander bands, opening-hand probabilities \(hyperge
- `find\_combos`: Detect 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\` \(and \`commander\` for Commander\) so near-miss suggestions are filtered to legal, in-color-identity adds. Use this instead of re
- `find\_synergies`: Given 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 a desired effect in words, and search\_cards for structured filters. \`limit\` defaults to 10 and caps a
- `get\_card`: Fetch 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 printing list matters \(choosing a specific art, set, or finish\).
- `get\_card\_image`: Fetch 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 external image hosts. Optionally pick a specific printing \(setCode\) or size \(small, normal, large, p
- `get\_card\_printings`: List 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\_rulings`: Fetch 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, and quote the ruling rather than paraphrasing from memory — rulings are among the most frequently h
- `get\_rule`: Fetch 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\_collection`: Summarize 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, and what\_can\_i\_build to rank commanders they could assemble. Requires a free API key \(send it as "X-A
- `rate\_deck`: Assess 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 from the official decision tree, and the rubric — then YOU finish the assessment: check for compact tw
- `resolve\_card\_names`: Check 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 card recommendation you generated: the most common failure in Magic assistance is confidently naming car
- `search\_cards`: Find 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 artifacts in Standard", "cards named Bolt". Use semantic\_card\_search instead when the user describes
- `search\_my\_collection`: Search 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 search\_cards instead to search every Magic card regardless of ownership. Returns at most 100 owned car
- `search\_rules`: Semantic 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 \(e.g. 601.2a\). Filter kinds to \["ruling"\] for card-specific questions or \["rule","glossary"\] for general mechanic
- `semantic\_card\_search`: Vector 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 cheaper". This is a query Scryfall syntax cannot express. Use search\_cards instead for structured filt
- `upgrade\_deck`: Suggest 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 strategy; then call again WITH your derived \`strategy\` to get recommendations. Cuts are theme-alignment su
- `what\_can\_i\_build`: Given 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" from cards they physically have. Requires a free API key \(send it as "X-API-Key: \<key\>" or "Authoriza
