Browserbase is a serverless platform for running and managing headless browsers at scale. It lets you automate and monitor browser tasks with Playwright, Puppeteer, and Selenium—no infrastructure headaches.

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Browserbase tool account to Claude via Composio Connect, enabling it to start a new headless browser session now, download all artifacts from last session, retrieve debug URLs for active sessions, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

Connecting Browserbase tool to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Browserbase tool account

Back in Claude, ask it to connect to Browserbase tool or give it any Browserbase tool-related task.

For example, ask Claude to:

  • "Start a new headless browser session now"
  • "Download all artifacts from last session"
  • "Retrieve debug URLs for active sessions"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Browserbase tool account is ready to use.

What is the Browserbase tool Claude Connector, and what's possible with it?

The Browserbase tool MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Browserbase account. It provides structured and secure access to your headless browser environments, so your agent can launch browser sessions, capture artifacts, retrieve debug info, and manage session contexts—all at scale and with zero manual setup.

  • Automated browser session management: Instantly create, retrieve, and update browser sessions to run automated browsing tasks in isolated environments.
  • Headless testing and monitoring: Let your agent spin up new browser contexts for advanced testing, monitoring, or web scraping workflows—no local infrastructure needed.
  • Artifact and log retrieval: Automatically collect session artifacts (like screenshots, HAR files, or logs) after browser tasks complete for audit, debugging, or analytics purposes.
  • Real-time session debugging: Fetch live debug URLs so your agent (or you!) can connect and troubleshoot active sessions on demand.
  • Comprehensive session tracking: List, filter, and inspect all your browser sessions, including metadata, statuses, and historical activity, to stay on top of your automation fleet.

Troubleshooting

1. Why does Claude not use the Composio connector for Browserbase tool?

The connector can show as connected, but Claude must use it in each Browserbase tool conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Browserbase tool again.

2. Why does Claude show an MCP server error before Browserbase tool connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Browserbase tool.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Browserbase tool.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Browserbase tool authorization link not work?

The Composio connector is one server. Your Browserbase tool account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Browserbase tool connection.
  • Composio creates a fresh Browserbase tool authorization link.
  • Open that link in your browser and finish the Browserbase tool sign-in.

4. Why do Browserbase tool actions fail after they worked before?

The Browserbase tool connection can expire or lose permission.

  • Ask Claude to inspect the Browserbase tool connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Browserbase tool account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Browserbase tool.
  • If the action still fails with a permission error, check that the connected account has that permission in Browserbase tool itself.

5. How do I switch to a different Browserbase tool account?

Claude can manage the Browserbase tool connection for you.

  • Ask Claude to disconnect or delete the current Browserbase tool account.
  • Ask Claude to connect Browserbase tool again.
  • Open the new Composio authorization link for Browserbase tool.
  • Sign in with the other Browserbase tool account in the browser.
  • After the account connects, ask Claude to retry the Browserbase tool task.

6. Why is my Browserbase tool connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Browserbase tool connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Browserbase tool tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Browserbase tool.

FAQ

Frequently asked questions

With a standalone Browserbase tool MCP server, the agents and LLMs can only access a fixed set of Browserbase tool tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Browserbase tool and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Browserbase tool tools.

Yes, absolutely. You can configure which Browserbase tool scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Browserbase tool data and credentials are handled as safely as possible.
