Common questions

Is Tab Hammer 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 on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 6 days ago, and the latest version (0.1.0) reached the registry 7 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

tab-hammer-mcp

An MCP server that lets AI agents list, group, move, focus, open, and close browser tabs through the Tab Hammer browser extension.

With the extension installed, run (Node 20 or newer):

npx tab-hammer-mcp install

It registers Tab Hammer's native messaging host with every Chromium browser it finds (Chrome, Chrome Beta/Dev/Canary, Chromium, Brave, Edge, Arc) and this server with every agent it finds (Claude Code, Claude Desktop, Codex, Cursor, VS Code, Windsurf, Devin Desktop), on macOS, Linux, and Windows. For any other agent it prints the config to paste. Then reload Tab Hammer in the browser and restart the agent.

  • npx tab-hammer-mcp doctor checks each browser's registration, whether the extension is connected, and each agent's config, and says how to fix what's wrong. It also says when a newer version is out: install copies the server, so update with npx tab-hammer-mcp@latest install.
  • npx tab-hammer-mcp uninstall undoes exactly what install did.
  • --only / --skip limit either command to some targets (--help lists them).
  • --extension-id also allows another build of the extension.
  • npx tab-hammer-mcp with no command runs the server over stdio.

The browser runs the host, which relays between the extension and this server over a local socket (a per-user named pipe on Windows). Both are copied to ~/.tab-hammer/mcp (%LOCALAPPDATA%\TabHammer\mcp on Windows) and run with the node you installed with.
