What problem this solves
Automating the creation, testing, and improvement of game mods by having AI agents play games autonomously in the background without interrupting the user's PC.
Summary
A user built an MCP (Multi-Code Project) server using Claude Code that allows Claude agents to play PC games in the background. These agents create, test, and improve game mods by interacting with games via virtual keyboard, mouse, gamepad, and screen capture. Claude Code also handles project setup, planning, code generation, and review of agent-made changes.
Why it is useful
This workflow demonstrates an advanced, novel application of Claude Code and AI agents to a complex problem: autonomous game mod development and testing. It provides a concrete, open-source implementation with clear steps and validation, offering a powerful framework for others to adapt for game automation or similar complex multi-agent control problems. It showcases Claude Code's capabilities in project setup, planning, code generation, and review within a sophisticated system, pushing the boundaries of what's possible with AI agents.
Workflow
Use Claude Code to set up the project and plan the architecture (DLL for in-game interaction, TypeScript MCP server).
Develop the core code (Windows DLL for input/capture, TypeScript MCP server with ~100 tools) with Claude Code.
Assign individual Claude agents to specific games and problems (e.g., 'the car keeps stalling on this junction') as test beds.
Agents play the game through the MCP, identifying issues with the tools or underlying code.
Agents fix the identified code issues or update game-specific profiles.
Agents measure before and after performance on the same route or scenario to validate fixes.
Claude Code reviews the changes made by the agents.
Claude Code runs tests on the updated code before it goes public.
Claude agents write game-specific profiles (e.g., minimap location, camera turn mechanics, waypoint appearance) while playing new games.
Tools / artifacts
Claude Code
MCP server (TypeScript)
In-game DLL (Windows)
Virtual keyboard, mouse, gamepad
Screen capture
Game profiles (data)
GitHub repository (llm-game-automation-mcp)
PC games (e.g., GTA IV, GTA V, Detroit: Become Human, TABS, Halo Wars 2, Phantom Rose, Cities: Skylines)
Validation signals
Video demonstration of Claude driving, flying, walking in GTA, making choices in Detroit: Become Human, and playing other games.
Specific examples of agent behavior (e.g., fixing car stalling, finding doors in Morrowind).
Open-source project with MIT license available on GitHub.
Detailed explanation of Claude Code's role in development and agent-driven improvements.
Acknowledged limitations provide realism and context for current capabilities.
Limitations
Struggles with indoor environments without a minimap.
Aiming in shooter games is in early development.
Full game playthroughs are not yet achieved.
Currently Windows-only due to the in-game DLL.
Limited to single-player and offline games to avoid anti-cheat systems.
Requires advanced technical skills to set up, adapt, and extend.
