Extentos MCP Server

Give your AI coding agent the tools to build smart-glasses apps.

Extentos is an MCP (Model Context Protocol) server that lets agents like Claude Code, Cursor, and Cline add smart-glasses capabilities — camera capture, voice triggers, live transcription, audio playback — to any Android or iOS app. The tools are deterministic: discovery, scaffolding, validation, and a browser-based simulator for end-to-end testing without hardware.

Works with Meta smart glasses today (Ray-Ban Meta, Oakley Meta, Meta Ray-Ban Display), with a multi-vendor architecture by design.

This repository is the public home of @extentos/mcp-server — releases, changelog, and issue tracking. The package ships on npm.

Install

Claude Code

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

Cursor — one click:

Cline / any MCP client

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

Requires Node 20+.

What your agent can do with it

Tool group	What it does
Discovery	getPlatformInfo, getCapabilityGuide, getCodeExample — the SDK capability catalog, per-feature call shapes in Kotlin + Swift, and canonical end-to-end patterns (voice Q&A, photo-describe, live transcription UI, …)
Scaffolding	generateConnectionModule — generates the connection UI + manifest + platform config for your app (Android or iOS)
Guidance	getVoiceCommandGuidance, getPermissions — implementation guidance the agent queries instead of guessing
Validation	inspectIntegration, validateIntegration — deterministic checks of the integration in your repo
Simulation	createSimulatorSession, getEventLog, getSimulatorStatus — a browser simulator running the same SDK code as production with only the transport swapped; the agent drives it and reads the event log to verify behavior
Production	getProductionChecklist, getCredentialGuide — the path from simulator to real glasses
Docs	searchDocs — bundled, versioned documentation topics

The workflow an agent typically runs: discover capabilities → scaffold the connection module → write handler code against the SDK → validate → simulate end-to-end → production checklist.
