LLMエージェントがシヴィライゼーションVIのフルゲームをプレイできるMCPサーバーです。

MCP互換クライアント(Claude Code、Codex、Gemini CLI、または自社のもの)を、実行中のCiv 6ゲームに接続できます。エージェントはゲーム状態の読み取り、ユニットの移動、都市管理、外交の実行、ターン終了など、すべてゲーム独自のルール強制APIを通じて行います。チートも視覚モデルも不要です。

civ6-mcp

An MCP server that lets LLM agents play full games of Civilization VI.

Connect any MCP-compatible client — Claude Code, Codex, Gemini CLI, or your own — to a running Civ 6 game. The agent reads game state, moves units, manages cities, conducts diplomacy, and ends turns, all through the game’s own rule-enforcing APIs. No cheats, no vision model required.

Capabilities

76 tools covering the full gameplay loop:

• Units — list, move, attack, fortify, found cities, build improvements, promote, upgrade
• Cities — inspect, set production, purchase units/buildings with gold, manage focus
• Map — explore terrain, resources, fog of war; get settle and district placement advice
• Research — browse tech and civic trees, set research targets
• Diplomacy — relationships, modifiers, delegations, embassies, alliances, peace deals
• Trade — propose and respond to deals, manage trade routes and destinations
• Government — swap policy cards, change governments, choose era dedications
• Governors — appoint, assign to cities, promote
• Religion — found pantheons and religions, select beliefs, track spread
• Great People — recruit, patronize, reject
• World Congress — vote on resolutions, manage diplomatic favor
• Victory — track progress across all victory conditions
• Game lifecycle — save, load, launch, restart, kill

Every turn, end_turn takes before/after snapshots and reports what happened: units damaged, cities grew, production completed, threats spotted near your cities.

Quick start

1. Configure Civ 6

Enable the FireTuner debug interface and configure recommended settings:

Windows: All three settings are available in the in-game Options menu. The Tuner setting appears as “Tuner (disables achievements)” under gameplay options.

macOS: The Tuner setting is not exposed in the menu. Edit AppOptions.txt directly and set EnableTuner 1:

~/Library/Application Support/Sid Meier's Civilization VI/Firaxis Games/Sid Meier's Civilization VI/AppOptions.txt

Linux: Same as macOS — edit AppOptions.txt directly and set EnableTuner 1:

~/.local/share/aspyr-media/Sid Meier's Civilization VI/AppOptions.txt

Install the Civ 6 SDK — the tuner server is part of the SDK, not the base game:

1. In Steam, go to Library → filter by Tools
2. Find and install “Sid Meier’s Civilization VI SDK”
