Your AI calls real web APIs through your browser session — no screenshots, no DOM scraping.

How It Works

  1. Install the CLI and load the Chrome extension
  2. Connect — the extension bridges your browser to a local server
  3. Use — your AI calls web APIs through your authenticated session

No API keys. No OAuth setup. If you're logged in, your AI can use it.

Works with any MCP client. Don't want MCP? Use CLI mode instead.

Quick Start

Requires Node.js 22+ and Chrome.

bash
npm install -g @opentabs-dev/cli
opentabs start

Load the extension from ~/.opentabs/extension in chrome://extensions/ (Developer mode → Load unpacked).

bash
opentabs plugin install <plugin-name>

Full walkthrough: Quick Start guide

What You Get

  • 100+ plugins, ~2,000 tools. Slack, Discord, GitHub, Jira, Notion, Figma, AWS, Stripe, and a lot more. One command to install, works immediately.

  • Built-in browser tools. Screenshots, clicking, typing, network capture — works on any tab, no plugin needed.

  • Build your own. Scaffold a plugin in one command, publish to npm, anyone can install it. Or point your AI at any website — it discovers the APIs and builds the plugin for you. Plugin Development guide

Security

  • Everything starts off. No tool executes until you explicitly enable it.
  • Code review built in. Your AI reviews the plugin source before you enable it.
  • Version-aware. Permissions reset when a plugin updates.
  • Three permission levels. Off, Ask (confirmation dialog), or Auto — per-plugin or per-tool.
  • Runs locally. No cloud. Full audit log. Anonymous telemetry (opt-out).

Use OpenTabs MCP with multiple AI models

TypingMind connects MCP tools at the workspace level, so once OpenTabs is connected, you can use it with different AI models in TypingMind instead of setting it up separately for each model. This MCP runs locally through the TypingMind MCP connector on your device.

Setup guide to use the local connector

Use this when the MCP server needs access to local files, apps, or private resources on your computer.

1

Open the MCP settings

In TypingMind, go to Settings, Advanced Settings, then Model Context Protocol and choose Setup Connector.

  1. Open TypingMind in your browser.
  2. Click the Settings icon.
  3. Go to Advanced Settings.
  4. Open the Model Context Protocol section.
  5. Click Setup Connector and choose This Device.

2

Run the connector command

Choose This Device, copy the command from TypingMind, and run it in Terminal. Keep the process running while you use MCP.

  1. Copy the setup command shown by TypingMind.
  2. Open Terminal on macOS or Windows Terminal on Windows.
  3. Paste and run the command.
  4. Approve the package install if Terminal asks you to proceed.
  5. Keep the Terminal window running while using MCP tools.
3

Add OpenTabs as a server

When the connector status is Ready, click Edit Servers and paste the MCP server configuration.

  1. Wait until the connector status shows Ready.
  2. Click Edit Servers.
  3. Paste the OpenTabs MCP server configuration.
  4. Save the server list.
  5. Refresh if you want to confirm the connector is still ready.

  }
}

Save the server list, open Plugins, enable the OpenTabs MCP tools, then select any supported AI model in TypingMind and use the tools in chat or assign them to an AI agent.

  1. Open the Plugins page in TypingMind.
  2. Enable the OpenTabs MCP tools.
  3. Start a chat and choose the AI model you want to use.
  4. Use the MCP tools in chat or assign them to an AI agent.
  5. Switch to another AI model whenever needed without reconnecting MCP.

Frequently asked questions

What is the OpenTabs MCP server used for?

OpenTabs is an MCP server that lets compatible AI clients connect to external tools and context. In TypingMind, you can add this MCP server once and make its tools available in your AI workspace.

Can I use OpenTabs MCP with multiple AI models in TypingMind?

Yes. TypingMind connects MCP tools at the workspace level, so you can use OpenTabs with different AI models such as Claude, ChatGPT, Gemini, or other models you have configured in TypingMind without setting up the MCP server separately for each model.

Why use OpenTabs MCP with TypingMind?

TypingMind is one of the best frontends for LLM chat because it brings multiple AI models, prompts, plugins, AI agents, API keys, and MCP tools into one workspace. With OpenTabs connected, you can use its MCP tools across your preferred models while keeping your chat workflow organized in TypingMind.

How do I connect OpenTabs MCP to TypingMind?

OpenTabs runs through the TypingMind local MCP connector. This is best when the MCP server needs access to local files, desktop apps, command-line tools, or private resources on your computer.

What tools does OpenTabs MCP provide in TypingMind?

OpenTabs exposes MCP capabilities that can be enabled from the TypingMind Plugins page and used in chat or assigned to AI agents.

Do I need to share my API keys with TypingMind to use OpenTabs MCP?

No. TypingMind is local-first and lets you keep your model providers, API keys, prompts, and MCP configuration under your control. If OpenTabs requires authentication, add the required headers, OAuth settings, or local configuration for that MCP server when you create the connection.
