Building tools
for the
next dimension.

Mixed Reality Creators makes developer tools for Unity and spatial computing — starting with Codex Bridge, an AI pair programmer that lives inside your editor.

Set up passthrough on the OVRCameraRig and add a dark overlay for the background.

Enabling passthrough on your OVRCameraRig component.

enable_meta_xr_passthrough("OVRCameraRig")

Done. Now creating a dark unlit material for the overlay.

create_material("DarkOverlay", shader="Unlit/Color", color="#000000cc")

Passthrough is active and the overlay material is assigned. Want me to add a fade-in animation on scene start?

Ask Codex about your scene...
Our First Tool

Codex Bridge,
native inside Unity.

Stop switching context. Codex Bridge puts OpenAI Codex directly inside the Unity Editor — with real awareness of your scene hierarchy, assets, console logs, scripts, and XR project. It's not a generic chatbot. It's a Unity-native AI co-developer.

Features

AI development,
the Unity way.

In-Editor Chat

A native Codex chat panel inside Unity. Open with Cmd+G and start building — no browser tab, no terminal.

Unity-Aware Tools

Codex can read scenes, create prefabs, add components, triage console logs, and manage assets — all through Unity-native APIs.

Meta XR Ready

Built-in helpers for Meta XR SDK. Enable passthrough on OVRCameraRig, discover Building Blocks, and verify scene setup in a single message.

Spatial Computing

Local-First & Private

Runs through your local Codex CLI or optional Claude Code CLI. No cloud backend. No data leaves your machine. Auth is handled by each provider's own CLI.

15 Context Modes

Smart Auto Compact bundle by default, plus Selection, Scene, File Tree, Git, Packages, Console — and 6 specialized modes for Build, Addressables, Input, Tests, XR, and ProBuilder.

Saved Chat History

Transcripts saved per project. Reopen any session and resume it on the original Codex thread. Export to Markdown, text, or JSON.

4 Assistant Modes

Switch between Builder, Inspector, Debugger, and Refactor. Each persona tunes Codex's approach to match your current task.

Image Attachments

Paste screenshots from your clipboard or attach files from disk. Show Codex exactly what you see in the Viewport or Inspector.

Context Modes

Give Codex
the right context

Attach live project context to every message automatically. Codex knows your hierarchy, console errors, package versions, and git state — without copy-pasting.

  • Auto CompactDefault bundle — version, scenes, console counts, skill state
  • NoneClean prompt, no context
  • SelectionInspector of selected objects
  • Active SceneFull scene hierarchy snapshot
  • File TreeProject asset listing
  • Project SettingsPlayer, Quality, XR settings
  • Git HistoryRecent commit log
  • Packagesmanifest.json resolved
  • ConsoleRecent log & error output

+ 6 specialized modes: Build Config · Addressables · Input Actions · Test Results · Meta XR Diagnostics · ProBuilder Diagnostics

Assistant Modes

The right AI
mindset for each task

Each mode shapes how Codex approaches your request. Switch mid-project to match what you're actually doing right now.

🔨

Builder

Makes concrete changes. Creates scripts, prefabs, and scene objects when needed.

🔍

Inspector

Analyzes first, explains architecture and dependencies before touching anything.

🐛

Debugger

Root cause focused. Prioritizes console output and error triage above all else.

Refactor

Improves what exists. Careful, conservative changes with minimal side effects.

34 Agent Skills

Specialized workflows,
not just a chatbot.

Each skill is a purpose-built workflow with its own triggers, required tools, and verification checklist — so Codex Bridge knows exactly how to approach each type of task.

How It Works

Up and running
in three steps

Works with OpenAI Codex CLI or Claude Code CLI — pick the provider you already have.

01

Install Your AI Provider

Install either OpenAI Codex CLI or Claude Code CLI locally. Codex Bridge detects and manages the connection for you.
