What is DeviceLink

DeviceLink gives an AI assistant read access to folders on your own computer.

Most AI clients cannot see your local files at all. Claude and ChatGPT in a browser or on a phone run in the cloud, with no path to your disk. DeviceLink is that path: you choose a folder, and your assistant can read what is inside it - and nothing else.

Your files are never uploaded, copied or stored. They are read on your machine, in response to a request you made, and streamed straight back into the conversation.

How it works

There are two ways to connect a folder. Both end up at the same place.

From your browser - nothing to install. Open devicelink.ai, sign in, and share a folder. Your operating system shows its own permission dialog, you pick the folder, and your browser tab becomes the connected device. It stays connected while that tab is open. This takes a few seconds and needs no terminal, no download and no admin rights.

With the DeviceLink agent - stays connected. Install the agent if you want the connection to survive closing the tab, or if you want to reach a machine you are not sitting at. It runs on macOS, Windows and Linux.

Either way you stay in control: the folders you shared are the only ones visible, and closing the tab or quitting the agent revokes access immediately.

What your assistant can do

DeviceLink configures its tool surface per device, so an assistant is offered only what that device actually supports. Every device provides:

Tool	What it does
fs_list	List the entries in a shared folder
fs_read	Read a single file
fs_info	Size and modified time, without reading contents
dl_ping	Check the device is responding

A machine running the DeviceLink agent can offer more, including recursive listing and search across the folder.

Every tool is read-only. Nothing in DeviceLink can write to, move, rename or delete a file. That is not a limitation waiting to be lifted - it is the boundary the product is built on.

Security

Trust is the whole point of a product that reads your files, so the design is deliberately narrow:

• Read-only. No tool writes. Nothing can be modified or destroyed.
• Scoped to what you picked. Access is confined to the folders you shared. Paths outside them are refused, and the check is applied per path, in code - not left to the model's judgement.
• Consent from your own OS. The browser route uses the operating system's native folder-permission dialog. Your machine asks, you answer, and the scope is whatever you chose.
• Nothing stored. File contents pass through in response to a request and are not retained.
• Revoke instantly. Close the tab or stop the agent. Access ends with it.
• OAuth 2.1 with PKCE, dynamic client registration (RFC 7591) and token revocation (RFC 7009).

Getting started

1. Open devicelink.ai and sign in.
2. Add the DeviceLink connector to your AI client, or use the server URL above.
3. Share a folder - from your browser, or by installing the agent.
4. Ask your assistant to read something in it.

New accounts start with free credits, so you can try it before paying for anything.

Requirements

• The browser folder picker needs a Chromium-based browser such as Chrome or Edge.
• The DeviceLink agent runs on macOS, Windows and Linux.
• Works with any MCP client that supports remote servers over streamable HTTP, including Claude, ChatGPT, Cursor, Copilot, Windsurf and Cline.
