AI Forge – AI Agent Toolkit for Unity

Give your AI coding assistant real tools in your Unity project.

AI Forge lets a local AI agent - such as Claude Code, GitHub Copilot, Cursor, Cline or Windsurf, or any assistant that can read files and run terminal commands - actually work in your project: understand what's in it and build scenes. Every tool is self-describing, so the agent discovers what it can do on its own.

No MCP server to run, no plugin to keep alive. AI Forge writes a standard AGENTS.md and exposes plain command-line and file-based tools, so it works headless (CI/batch) and with any AI assistant, out of the box. It's a simpler, server-free alternative to an MCP integration.

How it works

• Each tool ships a capability manifest. AI Forge aggregates them into your project's AGENTS.md - the moment your agent opens the project it knows what it can run, and how, with zero setup.
• Run tools headlessly (-batchmode -executeMethod …) or, with the editor open, through simple request/response files. Everything survives the domain reloads a Unity operation can trigger.

Included (free)

• Project Lens - index your project into an AI-readable catalog (types, prefabs, materials, scenes, ScriptableObjects) and query it: text search, prefabs-with-a-component, types-deriving-from, reverse usages.
• Scene Smith - build and populate scenes from a simple declarative spec: objects, prefabs, arrange patterns, camera and lighting.
• Core - the discovery registry, the AGENTS.md writer, and the shared file-bridge runtime.

Works with any local AI coding assistant (Claude Code, GitHub Copilot, Cursor, Cline, Windsurf, and others). AI Forge is editor-time tooling for AI-assisted development - it does not add runtime AI to your game.

Want more? AI Forge Pro adds screenshot verification (so the agent sees its own results), owned-asset import, advanced scene authoring and deep project audits. Pro is self-contained - it already includes this free toolset, so you can start with either one.
