Lorcana MCP Server

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.

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.

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.

---

Enriched columns

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

---

Data sources

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

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.
