MTG Bench is an MCP server with 19 tools an agent can call, among them check_deck_legality, commander_staples, deck_stats. It answers at https://mtgbench.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Magic: The Gathering card search, rules, rulings, deck analysis, brackets, and combo detection.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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 mo Inputs: format, cards, commander |
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 Inputs: commander, limit, minSynergy |
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 Inputs: format, commander, cards |
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 filte Inputs: cards, commander, format, limit |
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_car Inputs: cardNames, colors, format, types, manaValueMin, manaValueMax |
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, Inputs: name, id, slug |
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 Inputs: name, id, setCode, version |
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. Inputs: name, id, slug |
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 paraph Inputs: name |
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. Inputs: ref |
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 t |
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 r Inputs: cards, commander |
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 Inputs: names, text |
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 Bol Inputs: name, colors, colorIdentity, types, supertypes, manaValueMin |
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 Inputs: query, colors, types, notInDecks, limit |
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-sp Inputs: query, kinds, limit |
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 Inputs: query, colors, format, types, manaValueMin, manaValueMax |
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 `s Inputs: format, cards, commander, strategy, budget, maxCardPrice |
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 Inputs: limit, missing |

Yes. It is published by mtgbench.com and served from mtgbench.com, the vendor's own domain: https://mtgbench.com/mcp.
19, as returned by the server's own tools/list on 31 August 2026: check_deck_legality, commander_staples, deck_stats, find_combos, find_synergies, get_card, get_card_image, get_card_printings, and 11 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mtgbench.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
