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 Unity-MCP Bridge is a high-performance Model Context Protocol server that grants AI agents full programmatic access to the Unity Editor.
By executing C# scripts directly within the Editor, it allows AI tools to interact with the active Unity context, moving beyond standard code generation to full project manipulation.
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
Close the feedback loop with automated verification. The agent can run tests, trigger Playmode, simulate precise player input, and monitor game state in real time.

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
