4. Connect your Browserbase tool account

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

For example, ask Cowork 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 Cowork, and your Browserbase tool account is ready to use.

What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.

With Composio Connect, Cowork can securely access apps like Browserbase tool through MCP without you sharing account credentials directly with the agent.

What is the Browserbase tool MCP server, 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.

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.

Karan skipped his own birthday party to fix our critical issue. It was 10pm and he diverted his Waymo to help us instead. This really sets the bar — it shows the commitment you need when users rely on your software.

A lot of students tell us that the moment their connected tools start talking to each other inside Opennote feels almost magical. The agent just knows them, and it's immensely helped keep new users on the platform.

Abhi Arya

Co-founder, Opennote

We chose Composio over Pipedream because it delivered depth where it mattered — niche tools and tricky edge cases other platforms simply ignored. That gave us confidence to scale without compromising.

Nirman Dave

CEO, Zams

As a solo builder, shipping fast is life or death. The only way I can outcompete incumbents is by outmanoeuvring them. Getting bogged down managing agent auth would have been a death sentence.

Ryan Yu

Founder, Extra Thursday

Before Composio, adding tool integrations was slow and resource-intensive. Each one could take weeks of engineering time, and maintaining them meant constantly keeping up with API changes.

With hands-on help from their founder, we integrated Gmail and Google Drive in just 30 minutes. This level of personal support and commitment is exactly what startups should strive for.
