The industry is converging on the very same idea. MCPs for all their merit can be token hungry, slow, and unreliable for complex tool chaining. However, coding agents have become incredibly good at working with CLIs, and in fact they are far more comfortable working with CLI tools than MCP. With Composio's Universal CLI, your coding agents can talk to over 1000+ SaaS applications. With Browserless, agents 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 — all without worrying about authentication. This guide walks you through Composio Universal CLI and explains how you can connect it with coding agents like Claude Code, Codex, OpenCode, etc, for end-to-end Browserless automation. ## 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) - [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 The idea behind building the universal CLI is to give agents a single command interface to interact with all your external applications. Here's what you'll get with it: - Agent-friendly: Coding agents like Claude Code, Codex, and OpenCode can use CLI tools natively — no MCP setup required. - Authentication handled: Connect once via OAuth or API Key, and all CLI commands work with your credentials automatically. - Tool discovery: Search, inspect, and execute 20,000+ tools across 1000+ apps from one interface. - Trigger support: Use triggers to listen for events across your apps, powered by real-time webhooks or polling under the hood. - Type generation: Generate typed schemas for autocomplete and type safety in your projects. ## Connect Browserless to CLI ### Prerequisites Install the Composio CLI, authenticate, and initialize your project: ```bash # Install the Composio CLI curl -fsSL https://composio.dev/install | bash # Authenticate with Composio composio login ``` ## 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. ## Complete Code None listed. ## Conclusion - Try asking your coding agent to perform various Browserless operations - Explore cross-app workflows by connecting more toolkits - Set up triggers for real-time automation - Use composio generate for typed schemas in your projects ## How to build Browserless MCP Agent with another framework -

The Composio Universal CLI is a single command-line interface that lets coding agents and developers interact with 1000+ SaaS applications. It handles authentication, tool discovery, action execution, and trigger setup — all from the terminal, without needing to configure MCP servers. ### Which coding agents work with the Composio CLI? Any coding agent that can run shell commands works with the Composio CLI — including Claude Code, Codex, OpenCode, OpenClaw, and others. Once the CLI is installed, agents automatically discover and use the composio commands to interact with Browserless and other connected apps. ### How is the CLI different from using an MCP server for Browserless? MCP servers require configuration and can be token-heavy for complex workflows. The CLI gives agents a direct, lightweight interface — no server setup needed. Agents simply call composio commands like any other shell tool. It's faster to set up, more reliable for multi-step tool chaining, and works natively with how coding agents already operate. ### How safe is my Browserless data when using the Composio CLI? 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. You can also bring your own OAuth credentials for full control. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
