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 Builtwith, agents can get all websites using shopify in 2024, show historical tech changes for example.com, find online stores selling nike shoes, 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 Builtwith automation. ## Also integrate Builtwith with - [OpenAI Agents SDK](https://composio.dev/toolkits/builtwith/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/builtwith/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/builtwith/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/builtwith/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/builtwith/framework/codex) - [OpenClaw](https://composio.dev/toolkits/builtwith/framework/openclaw) - [Hermes](https://composio.dev/toolkits/builtwith/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/builtwith/framework/google-adk) - [LangChain](https://composio.dev/toolkits/builtwith/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/builtwith/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/builtwith/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/builtwith/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/builtwith/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 Builtwith 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 Builtwith MCP server, and what's possible with it? The Builtwith MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your BuiltWith account. It provides structured and secure access to web technology profiling and competitive intelligence data, so your agent can perform actions like analyzing website tech stacks, discovering competitor technologies, generating domain lists, and recommending similar sites on your behalf. - Comprehensive website technology profiling: Instantly analyze the current and historical tech stack of any website, including CMS, analytics, hosting, and more. - Bulk domain and technology list generation: Have your agent create and export lists of domains using specific technologies, or generate tailored files for large-scale research or outreach. - Competitor and product discovery: Identify financial, e-commerce, or product data for domains and uncover new market entrants or online retailers selling specific products. - Technology usage trends and datasets: Query historical datasets to track how specific technologies have been adopted across the internet over time, supporting market research and technology forecasting. - Intelligent site recommendations: Request suggestions for websites with similar technology profiles to a given domain, helping expand prospecting or research lists with relevant leads. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `BUILTWITH_CREATE_DOMAIN_LIST_FILE` | Create Domain List File | Tool to create a txt or zip file from a list of domains. use when preparing a domain list for bulk or firehose lookups. | | `BUILTWITH_DATASETS_LOOKUP` | Datasets Lookup | Tool to access mass internet technology usage information from 2000 to today. use when you need historical technology usage trends for a domain. | | `BUILTWITH_DOMAIN_API_LOOKUP` | Domain API Lookup | Tool to retrieve current and historical technology information of a website. use after confirming the domain to lookup. | | `BUILTWITH_FINANCIAL_API_LOOKUP` | Financial API Lookup | Tool to fetch financial data for a domain. use when you need company financials for us or uk registered websites. | | `BUILTWITH_FREE_API_LOOKUP` | Free API Lookup | Tool to access last updated dates and counts for technology groups and categories for websites. use when you need a snapshot of technology usage timing for a domain. | | `BUILTWITH_GET_LIST_WITH_META` | Lists API Get List With Meta | Tool to retrieve a list of websites using a specified technology, including metadata. use when you need detailed company and site information for sites using a particular technology. | | `BUILTWITH_LISTS_API_GET_LIST` | Lists API Get List | Tool to retrieve a list of websites using a specific technology. use when you want to find sites leveraging a particular tech. | | `BUILTWITH_MCP_API_LOOKUP` | MCP API Lookup | Tool to query live web technologies for a root domain. use after confirming a valid domain name. | | `BUILTWITH_PRODUCT_API_LOOKUP` | Product API Lookup | Tool to find websites selling specific ecommerce products. use when you need to discover online retailers offering a given product name or query a domain's product listings (e.g., 'dom:jbhifi.com.au'). | | `BUILTWITH_RECOMMENDATIONS_API_LOOKUP` | Recommendations API Lookup | Tool to generate a list of websites with similar technology profiles. use when you need technology recommendations for a given domain lookup. | | `BUILTWITH_REDIRECTS_API_LOOKUP` | Redirects API Lookup | Tool to retrieve live and historical redirects for a website. use after confirming the exact root domain to gather inbound and outbound redirect timelines. | | `BUILTWITH_SOCIAL_API_LOOKUP` | Social API Lookup | Tool to retrieve domains associated with social media profile urls. use when you need to map social profiles to root domains. | ## Supported Triggers None listed. ## Complete Code None listed. ## Conclusion -

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 Builtwith and other connected apps. ### How is the CLI different from using an MCP server for Builtwith? 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 Builtwith 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 Builtwith 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)
