Tools

6 tools agents can invoke

Generate 30–42 lands for a Commander within a USD purchase budget, optionally with acceleration. Returns card quantities, reasoning, prices, coverage, warnings, and shopping links. Preview only: no saved build, email, purchase, or cart modification. Shopping imports match by card name; printing and final prices may differ. Always show warnings rather than describing a deficient build as optimal.
build_mana_base
Find lower-cost deck replacements using budgetswap. Input a full quantity-prefixed Commander decklist including the commander. Budget is USD. Returns proposed cuts/additions, role counts, warnings, estimated cost, individual card links and a TCGplayer cartUrl for recommended cards not marked owned. Owned is a quantity-prefixed list; locked/excluded are newline-separated card names. Nothing is purchased or saved publicly. Show all warnings and let the player choose swaps. Bracket analysis is guidance, not certification.
reduce_deck_cost
Repair deck roles and consistency using deckmender. Input a full quantity-prefixed Commander decklist including the commander. Budget is USD. Returns proposed cuts/additions, role counts, warnings, estimated cost, individual card links and a TCGplayer cartUrl for recommended cards not marked owned.

Bracket analysis is guidance, not certification.
repair_deck
Review a Commander bracket transition using bracketshift. Input a full quantity-prefixed Commander decklist including the commander. Budget is USD.

Bracket analysis is guidance, not certification.
change_deck_bracket
Find Commander candidates by name. The existing autocomplete may include non-commander cards; only the primary field is validated as a legendary creature. Use the exact commander name for build_mana_base.

How do I improve MTG Tools's ChatGPT Plugin discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
