License
Extentos license terms. The @extentos/mcp-server npm package is MIT-licensed (declared in its package.json, surfaced on the npm package page). The Android library (com.extentos:glasses) and the iOS library (Extentos) are distributed as public packages with proprietary source. This page states the current, verifiable licensing position per component.
This page states the current, verifiable licensing position for each Extentos component. Extentos is pre-1.0; where a component's formal license terms aren't yet finalized, this page says so plainly rather than implying more than is committed.
MCP server — MIT
The @extentos/mcp-server npm package is MIT-licensed. This is declared in the package's package.json ("license": "MIT") and is shown on the npm package page. MIT permits commercial use, modification, distribution, and private use, with the standard attribution and no-warranty terms.
This covers the MCP tooling you run via npx -y @extentos/mcp-server@latest — discovery, code generation, validation, and simulator orchestration. The code it generates into your app is yours to license however you choose; the generator is MIT.
Native libraries — public packages, proprietary source
The Android library (com.extentos:glasses + com.extentos:glasses-ui, package com.extentos.glasses.core) ships as a public artifact on Maven Central; the iOS library (Extentos) ships as a Swift package from swift-glasses on GitHub. You depend on the published packages and build against their public API — the library source is proprietary and not distributed.
There is no open-source grant for the libraries today, and no separate LICENSE file. If you need a specific license commitment — commercial use, redistribution — email hello@extentos.com and ask.
License position by component
| Component | Distribution | License position |
|---|---|---|
@extentos/mcp-server | npm | MIT (declared in package.json) |
Android library (com.extentos:glasses, :glasses-ui) | Maven Central (binary) | Proprietary; no open-source grant |
iOS library (Extentos) | Swift package (swift-glasses on GitHub) | Proprietary; no open-source grant |
| Web app, backend, docs | Not distributed | Proprietary |
Third-party dependencies
Extentos builds on third-party SDKs and libraries that carry their own licenses — most notably Meta's Device Access Toolkit (governed by Meta's developer terms, not Extentos's license) and the usual npm / Gradle / SPM dependency trees. Your obligations toward those are independent of Extentos's MIT grant on the MCP server. In particular, shipping to real Meta Ray-Ban hardware requires accepting Meta's developer terms via your own Meta Developer Center registration.

Extentos is an independent product. It is not affiliated with, endorsed by, sponsored by, or certified by Google, Meta, Luxottica, or Brilliant Labs. Where this documentation describes a vendor's platform, capabilities, or release plans, it describes that vendor's own published position and links the source; it does not speak for them.
Questions
If you need a clarification on licensing — commercial use, redistribution of the libraries, or a written license commitment ahead of the pending LICENSE file — email hello@extentos.com with the [license] prefix. The maintainer treats licensing questions as high priority because they block downstream adoption.
