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. Covering build and test workflows, our products reduce manual effort and shorten iteration cycles.
Our Products
A focused suite of AI tools
Unity Code MCP Server
A direct bridge between your AI agent and Unity.
The open-source Unity Code MCP Server gives your agent first-class access to the Unity Editor.
By executing C# scripts within the Editor, it grants agents direct programmatic access to the Unity Editor API.
It transforms your AI into a virtual developer capable of navigating complex hierarchies, authoring scenes, and validating game logic autonomously.
Explore
Maximum Project Visibility
Gain a 360-degree view of your Unity project. The server lets agents query the active scene hierarchy, inspect serialized component properties, and browse the project asset database.

Autonomous Scene & Asset Authoring
Move from ideation to implementation instantly. Execute C# scripts directly within the Editor to generate GameObjects, attach components, and modify asset parameters on the fly.
Learn more →Verify
Intelligent Play-Testing & QA
The agent can close the feedback loop with automated verification. It can run tests, trigger Playmode, simulate precise player input, and monitor game state in real time.
Learn more →Unity Code Agent
Fully featured AI agent inside Unity Editor.
Direct access to Unity Editor API. Autonomous work. Open source.
Unity Code Agent is designed for developers who want an AI assistant embedded directly into the Unity workflow, with enough project context and tool access to move beyond chat-style suggestions into practical editor automation.
Explore, build and verify workflows
By reading the full editor context, including reflection-only data and asset metadata, the AI can build a complete picture of the current project state instead of relying on source files alone.
It can create and update code, scenes, and assets, including shaders, imports, scriptable objects, and more.
The agent can close the feedback loop with automated verification. It can trigger Playmode, simulate precise player input, and monitor the game state in real time as part of a self-correcting workflow.
Includes support for
- MCP Servers — integrate Model Context Protocol servers
- Skills — load reusable prompt modules
- Hooks — intercept and customize session behavior
- Custom Agents — define specialized sub-agents
- Image Input — send images as attachments

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
