Chromium Bridge MCP Server

Русская версия A bridge between your Chromium-based browser and Claude Code. The official "Claude in Chrome" extension connects in some Chromium browsers (Arc, Vivaldi, and others) but automation hangs: its tools are built on the tab groups API, which is missing or broken there. This bridge uses only plain chrome.tabs / chrome.scripting / chrome.debugger, so it works in any Chromium browser that can load an…. Its 14 documented tools cover browser, page.

People connecting browser automation tools to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

01 · Install Chromium Bridge

Claude Code

claude mcp add dashi96-chromium-bridge -- npx -y chromium-bridge

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "dashi96-chromium-bridge": {
      "command": "npx",
      "args": [
        "-y",
        "chromium-bridge"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-07-17 - young repo, little track record yet

03 · What Chromium Bridge can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can check the connection to the extension, list tabs (id, title, URL), navigate to a URL, and find elements by text/role, returns refs.

The 14 tools it gives your agent

Extracted from the project's README - what chromium-bridge lets an agent do.

browser_status
- Check the connection to the extension
browser_tabs_list
- List tabs (id, title, URL)
browser_navigate
- Navigate to a URL; back/forward for history
browser_page_text
- Page title, URL, and visible text
browser_computer
- Mouse/keyboard/screenshots via CDP: clicks by coordinates or ref, drag, hover, type, key combos, scroll, zoomed region screenshot, wait
browser_read_page
- Accessibility tree with ref ids (filter=interactive)
browser_find
- Find elements by text/role, returns refs
browser_form_input
- Set input/textarea/select/checkbox/contenteditable value by selector or ref
browser_click
- DOM click by CSS selector (plain .click())
browser_upload_file
- Put files into an
browser_javascript
- Run JS on the page (await supported)
browser_console_messages
- Tab console (with a regex filter)
show all 14 tools
browser_network_requests
- Tab network requests (with a regex filter)
browser_resize_window
- Window size

Limitations (from the README)

- The extension lives in one browser profile - install it in the one you want to automate. - While the server is running, its periodic ping keeps the extension's service worker awake. If the worker is asleep anyway (e.g. the server has just started), a keepalive alarm wakes it within ~30 seconds, and the server waits up to 12 seconds for reconnection before erroring. - Trust model: the WS server listens on 127.0.0.1
