Common questions

Is Agent Chrome safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 2 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

Let your coding agents use the Chrome you already use.

Install · Let your agent install it · What it does · Tools · Security

Agent Chrome is a Chrome extension and an MCP server that let coding agents use your real, signed-in Chrome profiles. It works with Claude Code, Codex, Gemini CLI, Antigravity, Grok, Muse, Cursor, opencode and any other MCP client. Each agent works in its own tab group, and a blue border and an animated cursor show what it is doing. It can take screenshots and record video clips, and you can connect several Chrome profiles at once. The server runs on Cloudflare, or locally on your machine.

What you see while an agent works. This clip was recorded by the extension itself ( MP4 ).

If it's useful to you, please star the repo. It helps other people find it.

Install

You need Node.js 18 or newer and Google Chrome.

1. Run the installer

curl -fsSL https://agentchrome.dev/install | sh

In one pass, the installer:

Creates your account and saves the key to ~/.config/agentchrome/config.json with chmod 600.
Adds an MCP server named agentchrome to every agent it finds, in that agent's user-level config (table below).
Writes the agentchrome skill once, to ~/.agents/skills/agentchrome, and symlinks it into each agent's skills folder.
Unpacks the extension to ~/.agentchrome/extension.
Prints a pairing code and copies it to your clipboard.

To keep everything on your machine with no cloud at all, add --local. See Local mode.

2. Load the extension, once per Chrome profile

The installer opens chrome://extensions and shows the folder in Finder for you.

In chrome://extensions, turn on Developer mode.
Click Load unpacked and choose ~/.agentchrome/extension. Run agentchrome extension --path to print the full path.
Pin Agent Chrome, click it, paste the pairing code and press Connect.

To add another profile (Work, Personal, a client's), switch to that profile, load the same folder, and run agentchrome pair for a new code. Each profile appears as its own browser in list_browsers.

3. Use it

Ask any agent:

Use agentchrome to open news.ycombinator.com, screenshot it, and record a short clip scrolling the front page.

Or let your agent install it

Paste this into Claude Code, Codex or any other coding agent:

Install agentchrome for me by following https://github.com/ShadowWalker2014/agentchrome/blob/main/AGENT_INSTALL.md

The agent runs the installer, then tells you the one step only you can do: loading the extension in Chrome and pasting the code.

Use it from Claude.ai or ChatGPT

The server is a standard remote MCP server with OAuth, so chat apps can use it as a connector. You don't need the command line tool for this.

Claude (claude.ai, Claude Desktop, Cowork): open Customize > Connectors > Add custom connector, enter https://agentchrome.dev/mcp and press Connect.

ChatGPT: turn on Developer mode under Settings > Apps & Connectors > Advanced, then create a connector with the same URL and choose OAuth.

A sign-in page opens. Paste your account key, or press Create an account if you don't have one. Then ask in chat: *"Connect my Chrome."* The assistant calls pairing_code and walks you through loading the extension and pasting the code.

Where each agent is configured

Agent	Config written (user level)	Format
Claude Code	`claude mcp add --scope user` (`~/.claude.json`)	`http` with an `Authorization` header
Codex	`~/.codex/config.toml`	`[mcp_servers.agentchrome]` with `url` and `http_headers`
Gemini CLI	`~/.gemini/settings.json`	`httpUrl` and `headers`
Antigravity	`agy mcp add` and `~/.gemini/antigravity/mcp_config.json`	`serverUrl` and `headers`
Grok	`grok mcp add --scope user` (`~/.grok/config.toml`)	http with a header
Muse	`~/.config/muse/settings.json`	`type: "streamable-http"`
Cursor	`~/.cursor/mcp.json`	`url` and `headers`
opencode	`~/.config/opencode/opencode.json`	`type: "remote"`
Windsurf	`~/.codeium/windsurf/mcp_config.json`	`serverUrl` and `headers`

The installer backs up every JSON or TOML file it edits as .bak-agentchrome. The skill is linked into ~/.claude/skills, ~/.codex/skills, ~/.gemini/skills, ~/.gemini/antigravity/global_skills, ~/.cursor/skills and ~/.config/opencode/skills.

Gemini CLI note: Gemini turns off every MCP server in folders you haven't trusted, so gemini mcp list shows "Disabled" there. Trust the folder with /permissions inside Gemini, and the server turns on.

Pick agents, or use OAuth instead of a key

agentchrome install claude codex grok   # only these agents

agentchrome install --oauth # no secret in config files; each agent signs in through the browser

With OAuth, agents that support MCP sign-in (Claude Code, Codex, Gemini CLI and others) open a sign-in page on first use. Paste your account key once (agentchrome key prints it) and the agent receives short-lived tokens, refreshed for 90 days.

Add it by hand

claude mcp add --scope user --transport http agentchrome https://agentchrome.dev/mcp \

--header "Authorization: Bearer $(agentchrome key)"

codex mcp add agentchrome --url https://agentchrome.dev/mcp --bearer-token-env-var AGENT_CHROME_MCP_KEY

Any MCP client that speaks Streamable HTTP works. Use https:// /mcp with a bearer key, or point it at the URL and let OAuth discovery do the rest.

What it does

You can see what the agent is doing. A blue border goes around the page, a pill shows which agent is working with a Stop button, and the agent's own cursor glides to each target. The cursor turns into a hand over links and an I-beam over text, and carries the agent's logo and name. Your own mouse is never moved. Recordings look like a person using the page. record leaves out the border, the pill and the name tag, and draws a normal cursor ( MP4 ). Pass cursor: "agent" to keep the indicators, or "hidden" for no cursor.

Every agent gets its own tab group, named after its task (for example "Fix checkout bug"). The popup lists which agents are active, and lets you pause one or stop them all. Setup takes a minute. Load the extension, paste the code from the installer, and the profile is connected.

It also handles the parts of real websites that usually break browser agents:

Drag and drop works for native HTML5 drag events (Trello-style boards, file drop areas) and for pointer-based sliders and sortable lists.
File uploads never open the native file picker. The agent can pass real file paths from your computer, or file contents. If a click tries to open the picker, it is held back and the agent is told to fill it.
`alert`, `confirm`, `prompt` and "Leave site?" dialogs are reported to the agent instead of freezing it. A navigation the agent asks for leaves an unsaved page and says so.
New tabs opened by a link join the agent's group, and downloads are reported in the result of the click that caused them.
Pages that fail are explained: HTTP errors such as 404, DNS failures, crashed tabs, chrome:// pages that extensions can't touch, and file:// pages that need permission.
If you press Cancel on Chrome's "started debugging this browser" bar, every agent stops and is told why.

CLI

Command	What it does
`agentchrome setup [--server URL] [--key KEY] [--local]`	Creates an account or signs in, installs into agents, links the skill, unpacks the extension, prints a pairing code
`agentchrome pair`	Prints a new single-use pairing code, valid for 15 minutes

Tools

The tool names match Claude in Chrome, so prompts and skills written for it work unchanged.

Tool	What it does
`tabs_context`	Lists this session's tab group and tabs; creates a group with a tab if there is none. `all: true` lists every tab
`tabs_create` / `tabs_close` / `tabs_select`	Opens, closes or switches tabs inside the session group; `adopt` pulls a user tab into the group
`tab_groups`	Lists, creates, renames, recolors, collapses, moves or ungroups Chrome tab groups

`computer`	`screenshot`, `left_click`, `right_click`, `middle_click`, `double_click`, `triple_click`, `hover` / `mouse_move`, `left_click_drag` (HTML5 and pointer drags; `start_ref` or `start_coordinate`), `type`, `key` (combos like `cmd+a`), `scroll`, `scroll_to`, `wait`, `zoom`. Accepts coordinates or element refs, plus `modifiers`
`screenshot`	Captures the viewport, or with `fullPage: true` one long image of the whole page. It scrolls through first so lazy images load, and stitches apps that scroll inside a panel, such as Gmail, Notion and dashboards. JPEG or PNG; `save: true` returns a download link
`read_page`	Returns an accessibility tree with `ref_N` handles; `filter: "interactive"`, `ref_id` to read a subtree, `viewportOnly`

| find | Finds elements from a plain-language description and returns refs with coordinates
