# Give a coding agent eyes inside the game engine with your own MCP server

PaperChase agent use case (free feed entry), version 1.0. Source: [WillMakesTV (@WillMakesTV on X)](https://x.com/WillMakesTV/status/2113620727312355544), 2026-10-23.

## What they did

He wrote an MCP server that exposes the s&box engine to the model, then ran the build live on YouTube with several agents working on the project.

## Worth knowing

The lesson matches other engine integrations: agents do much better when they can query the scene and see results than when they only edit files blind. The full process is in the video rather than a written guide.

## Workflow template

```text
Expose engine actions and scene state through a small MCP server
Let the agent read the scene before editing it
Decide up front whether agents plan the build or only write code
```
