Build games faster with AI tools.
Signal Loop creates practical AI-powered tools that help game developers move from idea to implementation with less friction. From Unity automation to multi-file coding workflows, our products reduce manual effort and shorten iteration cycles.
Tools for teams building more than prototypes
Modern game development demands speed, flexibility, and constant iteration. Signal Loop helps studios and independent developers accelerate core production tasks with AI tools that fit directly into established workflows. The result is a faster path from concept to playable systems, cleaner technical execution, and more room for creative ambition.
Our Vision
We believe game developers should be able to pursue bigger ideas without being constrained by avoidable production overhead. Signal Loop exists to help teams prototype, refine, and ship stronger game experiences while reducing the time, cost, and operational risk that typically slow development down.
Our Mission
Signal Loop focuses on practical AI products that help developers work faster without compromising control. Whether the goal is to automate Unity workflows, shorten prototyping cycles, or improve AI-assisted coding, our tools are built to support teams shipping real products.
Our Products
A focused suite of AI tools
Signal Loop develops specialized tools for game developers working in Unity and Visual Studio Code. Each product is designed to solve a concrete workflow problem.
Unity Code MCP Server
Give AI agents direct, structured access to the Unity Editor.
Unity Code MCP Server connects AI agents directly to the Unity Editor via the Model Context Protocol (MCP), enabling them to perform virtually any editor operation — creating scenes, managing assets, configuring components, running tests, and more. Using dynamically executed C# scripts via the Roslyn compiler, an AI agent can perform any task a developer could execute manually.
Key Features
- Execute any Unity Editor action through generated C# scripts with full API access
- Work with scenes, GameObjects, prefabs, assets, and project configuration
- Run tests and inspect console output as part of AI-assisted workflows
- Support both HTTP and STDIO-based integration for MCP clients (Claude, Cursor, Windsurf)
- Extensible — add custom tools, resources, and prompts anywhere in your codebase
Built-in Tools
| Tool | Description |
|---|---|
| execute_csharp_script | Execute C# scripts with full API access. Returns status, output, and logs. |
| read_unity_console_logs | Read Unity console logs with a configurable entry limit. |
| run_unity_tests | Run EditMode, PlayMode, or all tests. Supports filtering by name. |
| get_unity_info | Returns project path and current server settings. |
Requirements
• Unity 2022.3 LTS or higher
• UniTask (async/await integration)
• uv Python package manager (for STDIO transport)
Unity Editor
Unity Code Agent
Use AI directly inside Unity to automate editor work and accelerate iteration.
Unity Code Agent brings an AI chat assistant directly into the Unity Editor. Describe what you want in plain language and let the agent handle the rest — from batch texture updates to complex scene operations, all without leaving Unity.
- Scene & GameObject operations with natural language
- Component and asset management
- Reduce repetitive manual work during prototyping
- AI assistance inside the Unity Editor — no external tools required
// Main game loop: update, physics, render
void GameLoop() {
while (isRunning) {
deltaTime = Time.deltaTime
UpdatePlayerInput()
UpdateGameState(deltaTime)
Physics.Simulate(deltaTime)
RenderFrame()
}
}
Loop Coder
A customizable AI coding assistant for complex, multi-file development.
Loop Coder is a Visual Studio Code extension built for developers who need more control than a basic code generation tool provides. Review all changes in a diff view, accept or reject per-file, and rewind interactions to refine without losing momentum.
- Generate and modify code across multiple files with clear review controls
- Preview changes, inspect diffs, and accept updates selectively
- Rewind the last interaction to refine prompts without losing progress
- Configure models, system prompts, and context for different tasks
