Opentabs MCP Server

Turns tabs into tools

What is the Opentabs MCP server?

Turns tabs into tools. That is what the opentabs mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.

The short version

The tools it exposes

The server publishes 2 tools. What each one is for:

  • Built — in browser tools.** Screenshots, clicking, typing, network capture — works on any tab, no plugin needed
  • Version — aware.** Permissions reset when a plugin updates

Getting it running

@opentabs-dev/cli on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

How it compares

This sits in the browser automation group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Opentabs's toolset — Built, Version — is a fair guide to whether it matches your workflow. It is maintained by opentabs-dev; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Opentabs to MCP-compatible AI assistants such as Claude and Cursor, exposing 2 tools (Built, Version) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Opentabs directly.
