lorcana-mcp 0.1.7

MCP server for enriching Disney Lorcana TCG card collections from TCGPlayer exports

lorcana-mcp

MCP server that connects Claude to Disney Lorcana card data. Export your collection from TCGPlayer, hand it to Claude, and get it fully enriched with ink cost, stats, keywords, abilities, and format legality — plus a ready-to-import file for dreamborn.ink.

---

Tools

Eight tools are available in Claude once the server is running:

Tool	What it does
enrich_csv	Enriches a raw TCGPlayer export with Ink, Cost, Type, Subtypes, STR/WIL/Lore, Inkable, Keywords, and Abilities. Writes an enriched CSV and a dreamborn.ink-ready import file next to the input.
lookup_card	Looks up any card by name. Returns full stats, ability text, format legality, and card image URL.
resolve_card	Fuzzy-resolves an informal, misspelled, or subtitle-less card name (e.g. "goofy musketeer", "elsa"). Returns a single confident match, a ranked top-3 to disambiguate, or nothing found.
search_cards	Searches the full card pool by color, type, rarity, set, cost range, keyword, ability text, or subtype — with pagination.
find_song_synergies	Finds every character that can sing a given song (or a raw cost threshold), split into Singer-keyword discount picks and plain cost-qualifiers. Optionally flags which ones you own.
filter_collection	Filters your collection to cards legal in a given format: core, infinity, core_zh, core_ja, or poorcana.
audit_csv	Compares an enriched collection against live API data and reports any stale or wrong fields.
analyze_deck	Analyzes a raw deck list (4x Card Name per line) for ink curve, inkable split, color split, card types, estimated lore/turn, and Core Constructed legality (60-card min, max 4 copies, ≤2 ink colors).

Usage

Once the server is connected, just talk to Claude naturally. No slash commands needed.

Enrich a collection

Export your collection from TCGPlayer → My Collection → Export CSV, then:

"Enrich my collection at /Users/me/Downloads/Lorcana_063026.csv"

Claude will fetch card data from the APIs and write two files next to your input:

• enriched_Lorcana_063026.csv — your collection with 10 new columns
• dreamborn_Lorcana_063026.csv — ready to import at dreamborn.ink

On re-runs, pass the previous enriched file as a cache to skip already-seen cards:

"Enrich /Users/me/Downloads/Lorcana_new.csv using /Users/me/lorcana/enriched_Lorcana_old.csv as cache"

Look up a card

"Look up Mirage - Super Recruiter"

"What are the stats on Alma Madrigal - Heart of the Family?"

"Is Will o' the Wisp legal in Core?"

Returns: ink color, cost, type, subtypes, STR/WIL/Lore, inkable status, keywords, full ability text, format legality, and a card image URL.

Resolve an informal or misspelled card name

"Find the card 'goofy musketeer'"

"What's that card 'big pete'?"

"Look up 'elsa' — not sure which version"

Tokenizes the query and scores it against every card's name and subtitle, tolerating missing dashes, missing subtitles, word order, and minor typos. Returns full detail for a single confident match, a ranked top-3 with confidence scores when several cards are plausible (e.g. a bare name matching every printing of that character), or nothing if the query doesn't resemble any card.

Search the full card pool

"Show me all Evasive characters in Amethyst that cost 3 or less"

"Find Toy characters"

"Search for Rare Steel cards from Wilds Unknown"

Filters: ink color(s), card type (Character / Action / Item / Location / Song), rarity, set name, cost range, keyword, ability text substring, and subtype — all combinable, plus pagination (offset + limit). Results are grouped by ink color and sorted by cost.

Find who can sing a song

"Which characters can sing Be Our Guest?"

"Show me Amber characters that can sing a cost-7 song"

"Who can sing Friends on the Other Side, and which ones do I own?" (pass your enriched collection CSV)

A character can sing a song if its printed cost meets the song's cost outright, or it has a matching Singer X keyword — Singer lets a cheap character punch above its actual cost for singing purposes only. Results split into Singer-keyword "discount" picks (highest Singer value, then cheapest actual cost) and plain cost-qualifiers (cheapest first). Pass collection_csv to flag ownership.

Filter your collection by format

"Which of my cards are legal in Core Constructed?"

"Show me my Infinity-legal cards grouped by ink color"

"What Poorcana-legal cards do I have in Amber?"

Valid formats: core, infinity, core_zh, core_ja, poorcana

Poorcana filtering uses the Rarity column in your enriched CSV (Common + Uncommon only) — no API call needed.

Core/Infinity/regional legality comes from duels.ink, which tracks the current rotation for each region.

Audit an existing enriched file

"Audit my collection at /Users/me/lorcana/enriched_collection.csv"

Useful after a new set releases or if a card's data looks wrong. Compares every non-promo card against live API data and reports field-by-field discrepancies.

Analyze a deck list

"Analyze this deck: 4x Goofy - Musketeer, 4x Elsa - Spirit of Winter, ..." (paste a full list, one card per line)

Accepts 4x Card Name or 4 Card Name; quantity defaults to 1 if omitted. Lines starting with # or // are treated as comments.

Returns: ink curve (1-2/3-4/5-6/7+ cost brackets), inkable vs. uninkable count, color split, card type split, an estimated lore-per-turn (sum of Character lore values), a Core Constructed legality check (60-card minimum, max 4 copies of any card, at most 2 ink colors), and any card names that couldn't be resolved.

Enriched columns

The enricher adds these 10 columns to the raw TCGPlayer export:

Column	Description
Ink	Ink color(s) — dual-ink cards show both, e.g. Amber, Steel
Ink Cost	Numeric cost to play (1–12)
Card Type	Character / Action / Action - Song / Item / Location
Subtypes	e.g. Storyborn, Hero, Toy
Strength	⚔ stat — blank for Actions, Items
Willpower	🛡 stat — blank for Actions, Items
Lore Points	◆ gained per quest — blank for Actions, Items
Inkable	Yes / No
Keywords	Comma-separated: Evasive, Shift 3, Singer 5, Resist +1, etc.
Abilities	Full card text, pipe-separated lines

---

Data sources

Source	Sets	Used for
LorcanaJSON	All sets (1–14+)	Primary source for Set 12+; fallback for 1–11
lorcana-api.com	Sets 1–11	Preferred for Sets 1–11 (richer body text)
duels.ink	All sets	Format legality, card images

Card data is cached locally for 24 hours at ~/.cache/lorcana-mcp/. Manage the cache with the CLI:

lorcana-mcp cache stats   # show entry count, expiry status, and file size
lorcana-mcp cache clear   # delete all cached responses (fresh fetch on next use)

---

Supported sets

Set	Name
1	The First Chapter
2	Rise of the Floodborn
3	Into the Inklands
4	Ursula's Return
5	Shimmering Skies
6	Azurite Sea
7	Archazia's Island
8	Reign of Jafar
9	Fabled
10	Whispers in the Well
11	Winterspell
12	Wilds Unknown
13	Attack of the Vine!
14	Hyperia City

New sets are picked up automatically via LorcanaJSON as long as the set name is added to the internal mapping. Open an issue if a new set isn't resolving.

---

TCGPlayer export format

Go to TCGPlayer → My Account → My Collection → Export. The raw file has columns like Product Name, Set Name, Number, Rarity, Condition, Printing, and Add to Quantity (this is the real owned-quantity column — Total Quantity is always blank in exports).

Promo cards: skipped in the dreamborn output because dreamborn uses internal promo set numbers that don't match TCGPlayer's format. Add them manually via dreamborn.ink's card search after importing the rest.
