# Capybara 2.5D Engine
The entire public engine interface lives in a single file: src/Game.ts. This gives your agent a stable, predictable surface to learn and call without getting lost in a massive codebase.
## Quick Start
Clone the engine, add the Capybara MCP to your coding agent, then start building. Grab an API key at developer.capybara.build.
01 · Clone the engine
$ git clone https://github.com/d-liya/capybara_2d_engine.git
$ cd capybara_2d_engine02 · Add the MCP
Same setup as the API console. Replace YOUR_API_KEY with your key, then run the command for your agent:
Run this in your terminal.
claude mcp add capybara-mcp -e CAPYBARA_API_KEY=YOUR_API_KEY -- npx -y capybara-mcp@latest
03 · Use your coding agent
Open the cloned repo in Claude Code, Codex, Cursor, or another MCP client. Ask the agent to build a scene — it can generate maps, characters, props, and HUD art through the MCP, then wire them into src/Game.ts.
### Assets look wrong?
Check the original file in src/data before regenerating. Generated art is usually fine — coding agents often wire it in with the wrong aspect ratio.
