Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@devicelink/dlink

DeviceLink CLI agent — secure, local-first device access with explicit user consent.

Share files from your machine with AI assistants (ChatGPT, Claude, etc.) through the Model Context Protocol (MCP). Your files never leave your device — they're streamed in real-time with your explicit permission.

Install

npm install -g @devicelink/dlink

Quick Start

# Sign in with your DeviceLink account
dlink signin

# Share a directory
dlink share /path/to/project

# That's it — ChatGPT can now access your shared files via MCP

Commands

| Command | Description | |---------|-------------| | dlink signin | Authenticate with DeviceLink | | dlink signout | Sign out and revoke device access | | dlink share <path> | Share a directory with MCP clients | | dlink status | Show connection status | | dlink debug on/off | Toggle debug logging |

How It Works

  1. Sign in — authenticate via Google OAuth using a device code flow
  2. Share directories — choose which folders to make available
  3. Connect — the agent maintains a secure WebSocket connection to the DeviceLink bridge
  4. Use — AI assistants call tools (list files, read files, search, grep) through MCP
  5. Control — you see every tool call in real-time and can disconnect anytime

Security

  • Files never stored on servers — streamed in real-time only
  • Ed25519 proof-of-possession — device identity is cryptographically verified
  • Encrypted credential storage — AES-256-GCM with machine-bound keys
  • Shared directory boundaries — path traversal protection, symlink escape prevention
  • Short-lived tokens — access tokens expire in 30 seconds, auto-refreshed

Configuration

Environment variables (optional):

| Variable | Default | Description | |----------|---------|-------------| | DLINK_CONTROL_URL | https://api.devicelink.ai | Controller API URL | | DLINK_BRIDGE_URL | wss://api.devicelink.ai/ws | Bridge WebSocket URL | | DLINK_DEBUG | false | Enable debug logging |

Requirements

  • Node.js 20 or later
  • Internet connection for authentication and MCP bridge
