# Commander Workshop MCP Commander Workshop is a local-first MCP server for building, checking, comparing, and fulfilling Magic: The Gathering Commander decks. It combines pinned rules and card data with your explicitly imported collection, keeps deck intent separate from ownership, and turns a complete plan into pulls, swaps, substitutes, proxies, or purchases. <!-- mcp-name: io.github.gregario/commander-workshop --> The server is useful for unconstrained brewing, inventory-first construction, Bracket 3 planning, and fixed-budget precon upgrades. It evaluates bounded complete candidates and says **best found under these constraints** rather than claiming a universal power score or mathematically perfect deck. ## Features | Need | What Commander Workshop provides | | --- | --- | | Brew or upgrade | Complete, legality-checked plans under composable constraints | | Understand a deck | Mana, curve, roles, packages, theme evidence, and uncertainty | | Use cards you own | ManaBox and mapped CSV imports with binder/deck locations | | Keep plans honest | Decklists never imply ownership; assembled-deck copies are reported | | Find missing cards | Non-reserving availability plus actionable fulfillment plans | | Respect a budget | Native USD/EUR constraints and 50-unit Bracket 3 upgrade presets | | Check prices | Local Scryfall estimates or optional read-only CardTrader quotes | | Integrate with agents | Eleven MCP tools and immutable, paginated resources over stdio | ## Privacy promise Your collections, binder names, locations, and physical-deck allocations remain local by default.

Optional marketplace pricing sends only the minimum printing requirements and reads credentials from the environment or MCP host secret store. ## Installation Commander Workshop requires Python 3.11 or newer.
