Evidence-first rewrite
0.9.0 is a clean break from the legacy MCP surface. It exposes deterministic evidence and explicit workflows; the client LLM makes deckbuilding decisions.
Added
- Revisioned local deck storage, guarded backup/restore, manual Archidekt and Moxfield interchange, exact identity reconciliation, and caller-configured categorization.
- Official Scryfall queries, immutable snapshots, shared corpus data, rulings, printings, and community tag evidence.
- Guarded Archidekt deck, folder, snapshot, pull, push, and conflict workflows with conservative rate handling.
- The complete documented Playgroup Public API surface with fixture-only writes where the provider has no cleanup.
- Eight exact statistics tools for draw, turn, mana-source, mulligan, package, inverse-count, and deck-summary calculations.
Surface
- 93 tools, one capability resource, and zero prompts.
- Default profile: 32/54/54 tools in read-only/local/remote.
- Complete profile: 57/80/93 tools in read-only/local/remote.
Breaking changes
- Modes are now
read-only,local, andremote. - Legacy tools, prompts, recommendation logic, simulations, and compatibility aliases were removed.
- Legacy data and configuration are not migrated automatically. The new stores use the versioned
v0.9application-data root.
Install
