peterdemartini-mtgdata-p01

An encrypted MTGJSON card-data snapshot, and the code to unpack it, for the author's mtg-skills Claude Cowork bundle. The sandbox those skills run in can install from PyPI but can't reach mtgjson.com, so this package is how the skills get their card data.

The data files are encrypted (AES-256-GCM). Without the key the package is of no use, so please don't depend on it. If you want MTGJSON data, download it from mtgjson.com.

Usage (for key holders)

import peterdemartini_mtgdata_p01 as mtgdata

mtgdata.info()                   # snapshot date, MTGJSON version, files
mtgdata.extract("~/mtgjson")     # verify, decrypt, decompress; returns the paths

MTG_DATA_KEY=... python -m peterdemartini_mtgdata_p01 extract --dest ~/mtgjson

extract checks every file against the sha256 in the (encrypted) manifest, and only replaces files in dest after all of them verify.
