Think of it as Claude Code for everything else. It works autonomously with your computer, local files, and applications to accomplish complex tasks. This guide walks you through the easiest and most secure way to connect your Browserbase tool account to Cowork 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. ## Also integrate Browserbase tool with - [OpenAI Agents SDK](https://composio.dev/toolkits/browserbase_tool/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/browserbase_tool/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/browserbase_tool/framework/claude-code) - [Codex](https://composio.dev/toolkits/browserbase_tool/framework/codex) - [OpenClaw](https://composio.dev/toolkits/browserbase_tool/framework/openclaw) - [Hermes](https://composio.dev/toolkits/browserbase_tool/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/browserbase_tool/framework/cli) - [Google ADK](https://composio.dev/toolkits/browserbase_tool/framework/google-adk) - [LangChain](https://composio.dev/toolkits/browserbase_tool/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/browserbase_tool/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/browserbase_tool/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/browserbase_tool/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/browserbase_tool/framework/crew-ai) ## Connect Browserbase tool to Claude Cowork ### Connecting Browserbase tool to Claude Cowork 1. Open Customize In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top. 2. Add the Composio MCP server Click Add custom connector and paste in the Composio MCP server URL: ```bash https://connect.composio.dev/mcp ``` ## 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. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `BROWSERBASE_TOOL_CONTEXTS_CREATE` | Create a new browser context | Tool to create a new browser context.

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. ### Can I use Tool Router MCP with Claude Cowork? 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. ### Can I manage the permissions and scopes for Browserbase tool while using Tool Router? 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. ### How safe is my data with Composio Tool Router? 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. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
