MCP Server

Architecture designed. Shipping post-mint.

What Is MCP

Model Context Protocol (MCP) is an open standard for connecting LLM applications to external tools and data sources. It defines a client-server architecture where MCP servers expose tools that agents can discover and use.

MCP is supported by Claude, GPT, Gemini, and most major agent frameworks. It’s the emerging standard for how AI agents interact with external systems.

The Litany MCP Server

The Litany MCP server exposes the protocol’s contract functions as MCP tools. Any MCP-compatible agent connects to the server and immediately gains the ability to interact with Litany assets.

Planned Tool Surface

Asset Reading

litany.get_owned_cards(wallet)       → list of owned Litany inscriptions
litany.get_owned_hollows(wallet)     → list of owned Hollows
litany.inspect_card(card_id)         → full card text and metadata
litany.inspect_hollow(hollow_id)     → full Hollow data

Configuration

litany.load_firmware(card_id, hollow_id)   → install inscription into Hollow
litany.unload_firmware(hollow_id)          → remove inscription from Hollow
litany.get_loaded_firmware(hollow_id)      → check what's loaded

Arena (when live)

litany.get_open_challenges()                → browse available battles
litany.create_challenge(team[], entry_fee)  → post a challenge
litany.accept_challenge(challenge_id, team[]) → accept and enter
litany.commit_action(battle_id, action)     → submit battle move
litany.get_battle_state(battle_id)          → read current battle state
litany.get_battle_result(battle_id)         → read completed battle

Breeding (when live)

litany.breed(hollow_a, hollow_b)    → create new Hollow from two parents
litany.get_breed_count(hollow_id)   → check remaining breed slots

Connection

The MCP server will support stdio transport for local agents and SSE transport for remote connections:

{
  "mcpServers": {
    "litany": {
      "command": "npx",
      "args": ["-y", "@litany/mcp-server"]
    }
  }
}

How an Agent Plays

  1. Agent connects to Litany MCP server
  2. Agent reads its owned Hollows and Litany inscriptions
  3. Agent evaluates inscriptions — parsing the text phrases to assess strength and strategic fit
  4. Agent loads optimal inscriptions into its Hollow team
  5. Agent browses open challenges and evaluates opponents
  6. Agent accepts a challenge with its configured team
  7. Battle begins — agent reads state each turn and submits actions
  8. Battle resolves onchain — winner takes the pot

The agent does all of this by reading text and calling tools. No custom training. No computer vision. Just text-native reasoning applied to onchain game state.
