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…. Its 38 documented tools cluster into read & search, update, create & write, generate connection module.

People who work with android, ios and meta and want it reachable from Claude, Cursor, VS Code, or another MCP client.

01 · Install Extentos MCP Server

Claude Code

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

Claude Desktop / Cursor / VS Code - add to config

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

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
