What is Extentos?

Extentos is an MCP server that lets AI coding agents — Claude Code, Cursor, Cline — add smart-glasses capabilities to Android and iOS apps: camera capture, voice triggers, live transcription, and audio playback. The tools are deterministic: the agent discovers the SDK surface, scaffolds the integration, validates it, and tests it end-to-end in a browser simulator before touching hardware.

It works with Meta smart glasses today (Ray-Ban Meta, Oakley Meta, Meta Ray-Ban Display), with a multi-vendor architecture by design. Think Stripe for smart glasses: your app integrates once, Extentos handles the vendor SDKs, credentials, permissions, and hardware connections underneath.

How to use Extentos

With Claude Code:

claude mcp add extentos -- npx -y @extentos/mcp-server@latest

Or add to any MCP client config:

{
  "mcpServers": {
    "extentos": {
      "command": "npx",
      "args": ["-y", "@extentos/mcp-server@latest"]
    }
  }
}

Then ask your agent to add glasses features to your app. Requires Node 20+.

Key features

• Discovery — the SDK capability catalog, per-feature call shapes in Kotlin and Swift, and canonical end-to-end code patterns
• Scaffolding — generates the connection UI, manifest, and platform config for your app
• Validation — deterministic checks of the integration in your repo
• Browser simulator — runs the same SDK code as production with only the transport swapped, so the agent can verify behavior end-to-end with no hardware
• Production guidance — checklist and credential guide for the path from simulator to real glasses

Use cases

• Add voice commands or a voice assistant to an existing mobile app, running on the wearer's glasses
• Capture photos or video from glasses and process them in your app
• Build and test a complete glasses integration without owning the hardware, then ship it to real devices

FAQ

Do I need smart glasses to use it?

No — the browser simulator runs the same SDK code as production, so agents build and verify the full loop without hardware. Real Meta smart glasses are the production target.

Does it need an account?

Discovery, validation, and guidance tools work anonymously. Creating simulator sessions and scaffolding use a free account — the server walks you through a device-code sign-in when needed.

Which glasses are supported?

Meta smart glasses today: Ray-Ban Meta, Ray-Ban Meta Optics, Oakley Meta HSTN, Oakley Meta Vanguard, and Meta Ray-Ban Display. The architecture is multi-vendor by design.
