For LLMs, agents & tooling

Card game knowledge files for LLMs

Browse indexed rules and cards where available, or follow official publisher links for games whose text is not indexed. Each game index shows its section coverage. Agents can check that coverage through the TCG Knowledge MCP server before searching.

1. Root index

/llm.txt

The entry point: one line per game with its knowledge index, full bundle, and section availability.
2. Per-game index

/{game}/llm.txt

Progressive disclosure per game: indexed text, official source links, and unavailable sections are labeled separately.
3. Full bundle

/{game}/llm-full.txt

One file per game. Indexed games include rules and may embed cards. Link-only games list official sources without copying publisher text.

Knowledge files by game

Section files are served at /{game}/llm/{rules|glossary|errata|cards}.txt. Indexed card line format: Name [id] | type | stats | rules text.

Frequently asked questions

What is llm.txt?
llm.txt is a convention for publishing LLM-readable documentation at predictable URLs. TCG Online publishes a root index at /llm.txt, a per-game index at /{game}/llm.txt, individual section files (rules, glossary, errata, cards), and a single-file bundle per game at /{game}/llm-full.txt.
Which card games are covered?
The game table on this page lists every published knowledge index. Coverage varies by game: some have indexed rules and cards, some provide official publisher links only, and preview or unavailable sections are labeled explicitly.
Where does the content come from?
Indexed files are generated from game-owned rules sources and card catalogs. For link-only games, the files point to official publisher pages without copying their rules or card text. Each section states what is available.
How big are the files?
Indexed rules sections are often tens to hundreds of kilobytes, and full card catalogs can reach about 1MB. The llm-full.txt bundle embeds cards only while it stays within a reasonable size. Link-only bundles are small source directories without indexed publisher text.
Can an agent query this knowledge over MCP instead of fetching files?
Yes, for indexed content. The read-only TCG Knowledge MCP server offers list_games, search_rules, search_cards, and get_card. Start with list_games to check coverage; search is unavailable for link-only games. The remote URL is https://api.tcg.online/mcp (staging: https://staging-api.cardgoat.org/mcp). Connection details are in /llm.txt and each game's llm-full.txt.
