This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Browserbase tool account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## 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) - [Claude Cowork](https://composio.dev/toolkits/browserbase_tool/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/browserbase_tool/framework/codex) - [Kimi Code](https://composio.dev/toolkits/browserbase_tool/framework/kimi) - [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) - [Pydantic AI](https://composio.dev/toolkits/browserbase_tool/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/browserbase_tool/framework/autogen) ## TL;DR ### How Atomic Agent connects to Browserbase tool Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication. Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account. ## Connect Browserbase tool to Atomic Agent ### Connect Browserbase tool to Atomic Agent - Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key. - In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart. - Ask Atomic Agent to do something in Browserbase tool. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Browserbase tool account, then return to Atomic Agent to continue. ### Headless setup Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file. ```bash COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY ``` ## 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.

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying. ### Why are Composio tools unavailable after saving a key? Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk. ### Does Composio have a free plan? The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection. ## Complete Code None listed. ## Conclusion ### Use Browserbase tool from Atomic Agent With your account connected, ask Atomic Agent to work with Browserbase tool in natural language. You can connect more apps through the same Composio integration as you need them.

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 Atomic Agent? Yes, you can. Atomic Agent 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)
