It treats the AI agent as a first-class teammate, planning, coding, and validating work through an Agent Manager dashboard with deep browser connectivity. In this guide, I will explain the easiest and most secure way to connect your Browser tool account to Antigravity IDE via Composio Connect, so it can copy highlighted text from this webpage, drag and drop a file to upload section, fetch and summarize main page content, and more without ever putting your account credentials at risk. ## Also integrate Browser tool with - [ChatGPT](https://composio.dev/toolkits/browser_tool/framework/chatgpt) - [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) - [Codex](https://composio.dev/toolkits/browser_tool/framework/codex) - [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) - [CLI](https://composio.dev/toolkits/browser_tool/framework/cli) - [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) ## TL;DR ### Why use Composio? Composio provides: - Access to 1,000+ managed apps from a single MCP endpoint. This makes it convenient for agents to run cross-app workflows. - Programmatic tool calling. Allows LLMs to write code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool response handling outside the LLM context. This minimizes context bloat from large tool responses. - Dynamic just-in-time access to thousands of tools across hundreds of apps. Composio loads the tools your agent needs, so LLMs are not overwhelmed by tools they do not need. ## Connect Browser tool to Antigravity ### Connect Browser tool to Antigravity Antigravity does not ship with one-click custom MCP install links yet, so configuration goes through the IDE's raw config file. The process takes under a minute. ### 1. Open the MCP Config Go to Antigravity Settings, open the Customizations tab, then click Open MCP Config to open mcp_config.json in the editor. ### 2. Get your API key Go to the [Composio Dashboard](https://dashboard.composio.dev/~/org/connect/clients/) and copy your API key. ### 3. Add Composio to mcp_config.json Paste the following configuration into the file: ```bash { "mcpServers": { "remote-composio": { "serverUrl": "https://connect.composio.dev/mcp", "headers": { "x-consumer-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. ## Creating MCP Server - Stand-alone vs Composio SDK Once connected, Antigravity can access the Browser tool MCP server via Composio to run actions that you authorize directly from the agent panel. ## Complete Code None listed. ## Conclusion ### Conclusion You have successfully connected Browser tool to Antigravity using Composio Connect. Your agent can now use Browser tool securely without exposing credentials in prompts or local scripts. ## How to build Browser tool MCP Agent with another framework - [ChatGPT](https://composio.dev/toolkits/browser_tool/framework/chatgpt) - [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) - [Codex](https://composio.dev/toolkits/browser_tool/framework/codex) - [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) - [CLI](https://composio.dev/toolkits/browser_tool/framework/cli) - [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) ## Related Toolkits - [Composio](https://composio.dev/toolkits/composio) - Composio is an integration platform that connects AI agents with hundreds of business tools.
