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 Browserless account to Antigravity IDE via Composio Connect, so it can download all invoices from your dashboard, extract product details from a competitor's site, take a screenshot of your homepage after login, and more without ever putting your account credentials at risk. ## Also integrate Browserless with - [ChatGPT](https://composio.dev/toolkits/browserless/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/browserless/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/browserless/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/browserless/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/browserless/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/browserless/framework/codex) - [Cursor](https://composio.dev/toolkits/browserless/framework/cursor) - [VS Code](https://composio.dev/toolkits/browserless/framework/vscode) - [OpenCode](https://composio.dev/toolkits/browserless/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/browserless/framework/openclaw) - [Hermes](https://composio.dev/toolkits/browserless/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/browserless/framework/cli) - [Google ADK](https://composio.dev/toolkits/browserless/framework/google-adk) - [LangChain](https://composio.dev/toolkits/browserless/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/browserless/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/browserless/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/browserless/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/browserless/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 Browserless to Antigravity ### Connect Browserless 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 Browserless MCP server, and what's possible with it? The Browserless MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Browserless account. It provides structured and secure access to browser automation tools, so your agent can perform actions like fetching web content, scraping data, generating PDFs, taking screenshots, and running custom browser scripts on your behalf. - Dynamic web content extraction: Instruct your agent to fetch full HTML content—including JavaScript-rendered pages—from any website. - Automated web scraping: Let your agent extract structured data from pages using CSS selectors, returning results in convenient JSON format. - On-demand PDF generation: Have your agent instantly generate PDFs from any webpage, with customizable parameters like format and filename. - Website screenshot capture: Direct your agent to take high-quality screenshots of entire pages or specific sections, supporting multiple image formats and options. - Custom browser automations: Empower your agent to execute tailored Puppeteer scripts, enabling powerful workflows like file downloads or bypassing bot protections. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `BROWSERLESS_DOWNLOAD_FILE` | Download file using Puppeteer script | This tool allows downloading files that Chrome has downloaded during the execution of puppeteer code. It sets up a blank page, creates a fresh download directory, injects the provided code, and executes it. Once the script finishes, any downloaded files from Chromium are returned with the appropriate content-type header. | | `BROWSERLESS_EXECUTE_CUSTOM_FUNCTION` | Execute Custom Function | A tool that allows executing custom Puppeteer scripts via HTTP requests. This endpoint enables users to run browser automation tasks without managing their own infrastructure. | | `BROWSERLESS_FETCH_HTML_CONTENT` | Fetch HTML Content | This tool fetches the complete HTML content of a webpage using Browserless's content API. It's designed to retrieve the full HTML contents of any website, including dynamically generated content. | | `BROWSERLESS_GENERATE_PDF` | Generate PDF from webpage | This tool generates a PDF from a specified webpage using browserless's PDF generation API. It allows specifying the URL of the webpage along with parameters such as format, filename, and waitUntil options to control the PDF generation process. | | `BROWSERLESS_SCRAPE_CONTENT` | Scrape webpage content using CSS selectors | A tool to extract structured content from a webpage by specifying CSS selectors. The tool navigates to the specified URL, waits for the page to load (including parsing and executing JavaScript), and returns the selected elements in a structured JSON format. | | `BROWSERLESS_TAKE_SCREENSHOT` | Take Screenshot | A tool that captures a screenshot of a webpage using browserless's screenshot API. The tool takes a URL and returns either a PNG or JPEG image. It includes options for full page capture, image type, quality, and clipping coordinates. | | `BROWSERLESS_UNBLOCK_PROTECTED_CONTENT` | Unblock Protected Content | This tool provides access to content from websites that implement bot protection mechanisms. It is designed to bypass various types of protection (such as CAPTCHA and bot detections) and return the HTML content of the protected webpage, with optional customization through parameters like waitFor, timeout, and stealth mode. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK Once connected, Antigravity can access the Browserless 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 Browserless to Antigravity using Composio Connect. Your agent can now use Browserless securely without exposing credentials in prompts or local scripts. ## How to build Browserless MCP Agent with another framework - [ChatGPT](https://composio.dev/toolkits/browserless/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/browserless/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/browserless/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/browserless/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/browserless/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/browserless/framework/codex) - [Cursor](https://composio.dev/toolkits/browserless/framework/cursor) - [VS Code](https://composio.dev/toolkits/browserless/framework/vscode) - [OpenCode](https://composio.dev/toolkits/browserless/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/browserless/framework/openclaw) - [Hermes](https://composio.dev/toolkits/browserless/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/browserless/framework/cli) - [Google ADK](https://composio.dev/toolkits/browserless/framework/google-adk) - [LangChain](https://composio.dev/toolkits/browserless/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/browserless/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/browserless/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/browserless/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/browserless/framework/crew-ai) ## Related Toolkits - [Supabase](https://composio.dev/toolkits/supabase) - Supabase is an open-source backend platform offering scalable Postgres databases, authentication, storage, and real-time APIs.

With a standalone Browserless MCP server, the agents and LLMs can only access a fixed set of Browserless tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Browserless and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Antigravity? Yes, you can. Antigravity 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 Browserless tools. ### Can I manage the permissions and scopes for Browserless while using Tool Router? Yes, absolutely. You can configure which Browserless 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 Browserless data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
