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 Browser tool account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Browser tool with - [ChatGPT](https://composio.dev/toolkits/browser_tool/framework/chatgpt) - [Antigravity](https://composio.dev/toolkits/browser_tool/framework/antigravity) - [OpenAI Agents SDK](https://composio.dev/toolkits/browser_tool/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/browser_tool/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/browser_tool/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/browser_tool/framework/claude-cowork) - [Grok Bot](https://composio.dev/toolkits/browser_tool/framework/grok-bot) - [Codex](https://composio.dev/toolkits/browser_tool/framework/codex) - [Grok Build](https://composio.dev/toolkits/browser_tool/framework/grok-build) - [Cursor](https://composio.dev/toolkits/browser_tool/framework/cursor) - [VS Code](https://composio.dev/toolkits/browser_tool/framework/vscode) - [OpenCode](https://composio.dev/toolkits/browser_tool/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/browser_tool/framework/openclaw) - [Hermes](https://composio.dev/toolkits/browser_tool/framework/hermes-agent) - [Pi](https://composio.dev/toolkits/browser_tool/framework/pi-agent) - [DeepSeek Harness](https://composio.dev/toolkits/browser_tool/framework/deepseek) - [Google ADK](https://composio.dev/toolkits/browser_tool/framework/google-adk) - [LangChain](https://composio.dev/toolkits/browser_tool/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/browser_tool/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/browser_tool/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/browser_tool/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/browser_tool/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/browser_tool/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/browser_tool/framework/autogen) ## TL;DR ### How Atomic Agent connects to Browser 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 Browser tool to Atomic Agent ### Connect Browser 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 Browser tool. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Browser 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 Browser tool MCP server, and what's possible with it? The Browser tool MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to browser automation tools. It provides structured and secure access to browser actions, so your agent can fetch web content, perform clicks, automate keyboard shortcuts, move the mouse, and interact with on-page elements just like a real user. - Fetch and analyze webpage content: Let your agent retrieve the full HTML or clean text of any web page for data extraction, analysis, or decision-making. - Automated mouse and keyboard interactions: Instruct your agent to perform precise clicks, double clicks, drags, and keyboard shortcuts to navigate, select, or manipulate content on the page. - Clipboard and text extraction: Have the agent copy highlighted text, read clipboard contents, or transfer data between the browser and other tools for seamless workflows. - Drag-and-drop automation: Enable your agent to handle complex drag-and-drop actions, such as moving files or rearranging lists, to mimic advanced user interactions. - Fine-grained UI element control: Direct your agent to move the mouse, press and hold, or release buttons at exact coordinates to interact with dynamic or custom web interfaces. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `BROWSER_TOOL_CREATE_TASK` | Run Browser Task | Run an AI-powered browser automation task. The AI agent will control a cloud browser to complete your task. It can: - Navigate websites, click buttons, fill forms - Extract data and return results - Handle multi-step workflows (login -> navigate -> extract) - Solve CAPTCHAs and handle dynamic content If there is no running browser session in context, call CreateTask to start one. AFTER CREATING A TASK: 1. Use GetSession with browser_session_id to get the liveUrl - share with user to watch live 2. Use WatchTask with watch_task_id to check progress and get the final result 3. Use StopTask if you need to abort TIPS FOR GOOD TASKS: - Be specific: "Click login, enter email 'test@test.com', click submit" - Break complex workflows into smaller tasks | | `BROWSER_TOOL_GET_OUTPUT_FILE` | Download Task File | Get a download URL for a file generated by a task. When a task downloads or creates files (PDFs, images, spreadsheets, etc.), they appear in WatchTask's outputFiles list. Use this to get a download URL. The download URL is temporary (presigned) - download promptly. | | `BROWSER_TOOL_GET_SESSION` | Get Session Live URL | Get the live URL to watch a browser session in real-time. Call this right after CreateTask to get the liveUrl. Always share this URL with the user so they can watch the AI agent working in the browser. The liveUrl opens a visual stream showing exactly what the browser agent sees and does. | | `BROWSER_TOOL_STOP_TASK` | Stop Browser Task | Kill a browser task and its session. Use this when the browser agent is in a bad state: - Task is stuck or taking too long - WatchTask shows the agent going in the wrong direction - Agent is looping or making no progress After stopping, call CreateTask again to start fresh with a new browser. | | `BROWSER_TOOL_WATCH_TASK` | Watch Browser Task | Poll a browser task to check progress and get results. Call this after CreateTask to monitor the task: - status='started' means still running, poll again - status='finished' means done, check output and is_success - status='stopped' means aborted - status='failed' means an error occurred Returns what the agent is doing (current_goal, current_url), screenshots from each step, and any files generated. If the agent is going wrong, use StopTask to kill it and start fresh. | ## Supported Triggers None listed. ## Troubleshooting ### Why is my API key rejected? 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 Browser tool from Atomic Agent With your account connected, ask Atomic Agent to work with Browser tool in natural language. You can connect more apps through the same Composio integration as you need them.

With a standalone Browser tool MCP server, the agents and LLMs can only access a fixed set of Browser tool tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Browser 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 Browser tool tools. ### Can I manage the permissions and scopes for Browser tool while using Tool Router? Yes, absolutely. You can configure which Browser 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 Browser 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)
