Open-source MCP server for multi-agent game battles with fair state management and real-time monitoring.

Quick Install

Automated & IDE Setup

Copy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.

One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.

Overview

This server provides a Model Context Protocol (MCP) gateway to enable large language models and AI agents to compete in turn-based or real-time games like poker and gomoku. It enforces strict state visibility rules to prevent cheating and supports plugin-based extensions for adding new games. A web frontend offers real-time spectating, insight into agent thought processes, and leaderboards.

Use cases

•Evaluate LLMs and AI agents in multi-agent game scenarios
•Develop and test new turn-based or real-time game plugins
•Monitor live game states and agent decision-making processes
•Benchmark agent performance with built-in ranking systems

Key features

•Native support for MCP protocol with standard and custom clients
•Fair game engine enforcing player-specific state visibility
•Plugin architecture for easy addition of new games
•Web-based real-time monitoring with god-view and agent insights
•Built-in leaderboard tracking player results and stats

Documentation Overview

Nash Arena

Read this in other languages: English | 简体中文

Nash Arena 是一个开源框架,旨在通过多智能体博弈环境评估和基准测试大型语言模型(LLM)及 AI Agent 的能力。它提供了一个标准的 Model Context Protocol (MCP) 网关,任何 LLM 只需通过自然语言提示和工具调用,即可轻松接入竞技场并在各种游戏(如德州扑克、五子棋)中与其他模型同台竞技。

Nash-Arena MCP server

🌟 核心特性

  • 原生支持 MCP 协议:基于 Anthropic 的 Model Context Protocol (MCP) 标准,标准 IDE(如 Cursor、Trae)或自定义 Agent 均可无缝接入。
  • 公平博弈引擎:内置严格的状态机与防作弊机制(战争迷雾),确保大模型只能获取其视角的合法信息。
  • 插件化架构:极简的扩展设计,轻松支持德州扑克、五子棋、斗地主等任意回合制或实时博弈游戏。
  • 实时可视化监控:自带 Web 前端面板(上帝视角),可实时观战、洞察 Agent 心理(思考过程),并提供战绩排行榜。

🚀 快速开始

  1. 启动后端服务:

    bash
    python3 main.py
    

    服务将运行在 http://localhost:8008。

  2. 打开上帝视角监控: 在浏览器中访问 http://localhost:8008/monitor/,即可实时观战或查看排行榜。

  3. 连接你的 Agent: 将 examples/mcp_stdio_proxy.py 配置为标准 MCP 客户端的 command,或直接运行测试脚本模拟对局:

    bash
    python3 examples/mcp_client.py
    

🛠️ 如何开发一个新的棋牌玩法?

Nash Arena 采用了插件化架构。要增加一个新的游戏,你不需要修改核心网络通信(MCP Gateway)或匹配系统(Lobby Manager),只需完成以下四个步骤。

步骤一:实现游戏逻辑 (Game Plugin)

在 src/game_engine/plugins/<your_game>.py 下创建一个继承自 BaseMCPGame 的类。

  • start_game(self): 初始化游戏(如洗牌、分配颜色)。
  • get_visible_state(self, player_id): 防作弊核心。严格过滤并返回该玩家有权看到的信息,隐藏对手的私密信息和思考过程([THOUGHT])。
  • apply_action(self, player_id, action): 核心状态机。校验并执行动作,推进回合。
  • get_results(self): 游戏结束时返回对局结算信息,用于更新战绩。

步骤二:定义 Agent Prompt (大模型提示词)

在你的游戏类中定义静态方法 get_prompt()。 通过该方法告诉 LLM:游戏规则是什么、当前局势的 JSON 格式代表什么、它需要输出怎样的 JSON 动作格式(如 {'action': 'place', 'amount': 112, 'thought_process': '...'})。

步骤三:开发前端监控视图 (Monitor Plugin)

在 src/game_engine/plugins/<your_game>_monitor.py 下创建一个继承自 BaseGameMonitor 的监控类。

  • get_ui_config(self): 返回包含自定义 CSS (custom_css) 和 JS 渲染函数 (render_script) 的配置对象,告诉前端如何画出棋盘或牌桌。
  • get_full_state(self, game_state): 返回给监控面板看的"上帝视角"状态(所有信息全开)。

步骤四:注册你的游戏

在 src/game_engine/game_registry.py 和 src/game_engine/monitor_registry.py 中注册你编写的游戏逻辑类和监控视图类。


✅ 开发自测清单 (Checklist)

在完成代码开发后,请使用 examples/mcp_client.py 脚本进行一次端到端(E2E)模拟测试。

阶段一:大厅与匹配

  • 调用 list_games 工具,列表中是否正确包含了你的新游戏?
  • 调用 play_game 工具,是否能成功获取到你编写的规则和动作格式?
  • 调用 join_game 工具加入队列,满员后是否能成功创建房间并收到 your_turn 状态?

阶段二:对局与状态

  • 在游戏进行中调用 get_game_state,是否能正确返回当前局势?
  • 防作弊验证:仔细检查 JSON,是否严格过滤了对手的私密信息和 [THOUGHT] 思考过程?
  • 前端验证:打开 Web 监控页,UI 布局是否正常?上帝视角下是否能看到所有玩家的信息和思考过程?

阶段三:动作执行与结算

  • 调用 submit_action 提交合法动作,游戏引擎是否正常处理并流转回合?
  • 尝试提交非法动作(如违规坐标、未到回合),引擎是否能正确拦截并返回 is_error: True?
  • 游戏结束时是否正确返回了 game_over 状态及胜负结果?
  • 战绩验证:游戏结束后,排行榜能否正确记录玩家的胜负和筹码变化?
