Meta Quest Developer Hub MCP

Access Meta Horizon OS development tools via the MQDH MCP server. This MCP is bundled with the Meta Quest Developer Hub application (v6.2.1+).

Prerequisites

1. Install MQDH

Download and install Meta Quest Developer Hub v6.2.1 or later:

• macOS: Download MQDH for Mac
• Windows: Download MQDH for Windows

2. Set MCP Path Environment Variable

The MCP server is bundled with MQDH. Set the path to the MCP executable:

macOS:

export MQDH_MCP_PATH="/Applications/Meta Quest Developer Hub.app/Contents/Resources/mcp-server"

Windows:

$env:MQDH_MCP_PATH = "C:\Program Files\Meta Quest Developer Hub\resources\mcp-server.exe"

Note: Paths may vary based on your installation. Check MQDH's AI Tools settings tab for the exact path.

3. Alternative: Use MQDH's Built-in Setup

MQDH v6.2.1+ includes an AI Tools settings tab with:

• One-click install for Cursor and VS Code
• Guided setup for Claude Desktop, Gemini CLI, Android Studio
• Manual configuration export for other tools

Quick Start

After setting up the environment variable and loading this skill:

skill_mcp(skill_name="mqdh", list_tools=true)

Then invoke tools:

skill_mcp(skill_name="mqdh", tool_name="fetch_meta_quest_doc", arguments='{"query": "hand tracking setup"}')

Available Tools

fetch_meta_quest_doc

Search and retrieve Meta Horizon OS documentation.

Example:

skill_mcp(skill_name="mqdh", tool_name="fetch_meta_quest_doc", arguments='{"query": "passthrough API Unity"}')

get_adb_path

Get the path to the bundled ADB executable.

Example:

skill_mcp(skill_name="mqdh", tool_name="get_adb_path", arguments='{}')

device_list

List connected Quest devices.

Example:

skill_mcp(skill_name="mqdh", tool_name="device_list", arguments='{}')

install_apk

Install an APK to a connected Quest device.

Example:

skill_mcp(skill_name="mqdh", tool_name="install_apk", arguments='{"apk_path": "/path/to/app.apk"}')

Use Cases

• Documentation Lookup: Quickly search Meta Horizon OS docs for APIs, best practices
• Device Management: List devices, install APKs, manage Quest headsets
• Development Workflow: Integrate ADB operations into AI-assisted development
• Troubleshooting: Find solutions in Meta's documentation

Workflow Examples

1. Look Up API Documentation

# Search for hand tracking documentation
skill_mcp(skill_name="mqdh", tool_name="fetch_meta_quest_doc", arguments='{"query": "hand tracking gesture detection"}')

# Search for passthrough setup
skill_mcp(skill_name="mqdh", tool_name="fetch_meta_quest_doc", arguments='{"query": "mixed reality passthrough Unity"}')

2. Device Operations

# List connected devices
skill_mcp(skill_name="mqdh", tool_name="device_list", arguments='{}')

# Install a build
skill_mcp(skill_name="mqdh", tool_name="install_apk", arguments='{"apk_path": "/builds/myapp.apk", "device_id": "1234567890"}')

Transport

This MCP uses STDIO transport to communicate with the LLM agent.

Troubleshooting

"Command not found": Verify MQDH_MCP_PATH points to the correct executable. Check MQDH's AI Tools settings for the exact path.

"MQDH not installed": Download MQDH v6.2.1+ from Meta Developer Portal.

"Device not found": Ensure your Quest is connected via USB and developer mode is enabled.

One-click setup preferred: Use MQDH's built-in AI Tools settings tab for automatic configuration with Cursor or VS Code.
