Meta Wearables Device Access Toolkit for iOS

The Meta Wearables Device Access Toolkit enables developers to utilize Meta’s AI glasses to build hands-free wearable experiences into their mobile applications. By integrating this SDK, developers can reliably connect to Meta’s AI glasses and leverage capabilities like video and audio streaming and photo capture.

The Wearables Device Access Toolkit is in developer preview. Developers can access our SDK and documentation, test on supported AI glasses, and create organizations and release channels to share with test users.

Including the SDK in your project

The Wearables Device Access Toolkit is distributed as a Swift Package.

1. In Xcode, select File > Add Package Dependencies…
2. Search for https://github.com/facebook/meta-wearables-dat-ios in the top right corner
3. Select meta-wearables-dat-ios
4. Set the version to one of the available versions
5. Click Add Package
6. Select the target to which you want to add the packages
7. Click Add Package

Developer Terms

• By using the Wearables Device Access Toolkit, you agree to our Meta Wearables Developer Terms, including our Acceptable Use Policy.
• By enabling Meta integrations, including through this SDK, Meta may collect information about how users’ Meta devices communicate with your app. Meta will use this information collected in accordance with our Privacy Policy.
• You may limit Meta’s access to data from users’ devices by following the instructions below.

Opting out of data collection

To configure analytics settings in your Meta Wearables DAT iOS app, you can modify your app’s Info.plist file using either of these two methods:

Method 1: Using Xcode (Recommended)

1. In Xcode, select your app target in the Project navigator
2. Go to the Info tab
3. Navigate to Custom iOS Target Properties and find the MWDAT key
4. Add a new key under MWDAT called Analytics of type Dictionary
5. Add a new key to the Analytics dictionary called OptOut of type Boolean and set the value to YES

Method 2: Direct XML editing

Add or modify the following in your Info.plist file.

<key>MWDAT</key>
<dict>
    <key>Analytics</key>
    <dict>
        <key>OptOut</key>
        <true/>
    </dict>
</dict>

Default behavior: If the OptOut key is missing or set to NO/<false/>, analytics are enabled (i.e., you are not opting out). Set to YES/<true/> to disable data collection.

Note: In other words, this setting controls whether or not you’re opting out of analytics:

• YES/<true/> = Opt out (analytics disabled)
• NO/<false/> = Opt in (analytics enabled)

Crash reporting

The Wearables Device Access Toolkit can capture crashes originating from SDK code, store them locally, and chain with any existing crash handler your app installs. Crash reporting is enabled by default.

To opt out, add a CrashReporting dictionary with an OptOut boolean set to true under the MWDAT key in your app’s Info.plist:

<key>MWDAT</key>
<dict>
    <key>CrashReporting</key>
    <dict>
        <key>OptOut</key>
        <true/>
    </dict>
</dict>

Default behavior: If the OptOut key is missing or set to NO/<false/>, crash reporting is enabled. Set it to YES/<true/> to disable SDK crash capture.

AI-Assisted Development

This repository ships one public DAT knowledge base as a single plugin, plus file-based artifacts for the tools that do not use plugins:

Tool	Public artifact	Recommended setup
Muse Code, Claude Code, Codex	plugins/mwdat-ios/	Add this GitHub repo as a marketplace, then install mwdat-ios
GitHub Copilot	.github/copilot-instructions.md	Auto-loaded by Copilot in VS Code
Cursor	.cursor/rules/*.mdc	Auto-loaded with glob-based triggers
AGENTS.md-compatible tools	AGENTS.md	Portable fallback for agents that read AGENTS.md
MCP-compatible editors	https://mcp.developer.meta.com/wearables	Connect as a remote HTTP MCP server; no authentication required

Muse Code, Claude Code, and Codex install from the plugin payload under plugins/. Copilot, Cursor, and AGENTS.md readers use the native file-based artifacts at repo root.

Muse Code

muse plugins marketplace add mwdat-ios-marketplace https://github.com/facebook/meta-wearables-dat-ios
muse plugins install mwdat-ios@mwdat-ios-marketplace
muse plugins approve mwdat-ios

Or use the helper script:

./install-skills.sh muse

Muse Code also reads AGENTS.md from your project root with no setup at all.

Claude Code

claude plugin marketplace add facebook/meta-wearables-dat-ios
claude plugin install mwdat-ios@mwdat-ios-marketplace

Or use the helper script:

./install-skills.sh claude

Codex

codex plugin marketplace add facebook/meta-wearables-dat-ios
codex plugin add mwdat-ios@mwdat-ios-marketplace

Or use the helper script:

./install-skills.sh codex

Other tool installs

Use the installer when you want the repo-native file surfaces for other tools:

./install-skills.sh copilot   # .github/copilot-instructions.md
./install-skills.sh cursor    # .cursor/rules/*.mdc
./install-skills.sh agents    # AGENTS.md
./install-skills.sh all       # Muse/Claude/Codex when available, plus Copilot/Cursor/AGENTS.md

Or run the helper remotely:

curl -sL https://raw.githubusercontent.com/facebook/meta-wearables-dat-ios/main/install-skills.sh | bash

What’s included

For static reference context, point your AI tool at the llms.txt endpoint. Installing the plugin registers https://mcp.developer.meta.com/wearables for live documentation search in Muse Code, Claude Code, and Codex. Other MCP-compatible editors can connect to that endpoint directly and use search_dat_docs. The public docs MCP server does not require authentication; do not configure tokens, OAuth, or custom authorization headers for it.
