Introduction

CLIs are eating MCPs. 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 850+ 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.

What is Universal CLI and why use it?

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 850+ 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.

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

During login you'll be redirected to sign in page, finish the complete flow and you're all set.

Composio CLI authentication flow

Connecting Builtwith to Coding Agents via Universal CLI

Once it is installed, it's essentially done. Claude Code, Codex, OpenCode, OpenClaw, or any other agent will be able to access the CLI. A few steps to give agents access to your apps.

  1. Launch your Coding Agent — Claude Code, Codex, OpenCode, anything you prefer.
  2. Prompt it to "Authenticate with Builtwith"
  3. Complete the authentication and authorization flow and your Builtwith integration is all set.
  4. Start asking anything you want.

Universal CLI Commands for Builtwith

You can also manually execute CLI commands to interact with your Builtwith.

Connect your Builtwith account

Link your Builtwith account and verify the connection:

bash
# Connect your Builtwith account (opens OAuth flow)
composio connected-accounts link builtwith

# Verify the connection
composio connected-accounts list --toolkits builtwith

Discover Builtwith tools

Search and inspect available Builtwith tools:

bash
# List all available Builtwith tools
composio tools list --toolkit builtwith

# Search for Builtwith tools by action
composio tools search "builtwith"

# Inspect a tool's input schema
composio tools info BUILTWITH_CREATE_DOMAIN_LIST_FILE

Common Builtwith Actions

Create Domain List File — Tool to create a txt or zip file from a list of domains

bash
composio tools execute BUILTWITH_CREATE_DOMAIN_LIST_FILE \
  --domains '["example.com","test.org","example.com"]'

Datasets Lookup — Tool to access mass internet technology usage information from 2000 to today

bash
composio tools execute BUILTWITH_DATASETS_LOOKUP \
  --LOOKUP "builtwith.com"

Domain API Lookup — Tool to retrieve current and historical technology information of a website

bash
composio tools execute BUILTWITH_DOMAIN_API_LOOKUP \
  --lookup "builtwith.com"

Financial API Lookup — Tool to fetch financial data for a domain

bash
composio tools execute BUILTWITH_FINANCIAL_API_LOOKUP \
  --lookup "robinhood.com"

Generate Type Definitions

Generate typed schemas for Builtwith tools to get autocomplete and type safety in your project:

bash
# Auto-detect language
composio generate --toolkits builtwith

# TypeScript
composio ts generate --toolkits builtwith

# Python
composio py generate --toolkits builtwith

Tips & Tricks

  • Always inspect a tool's input schema before executing: composio tools info <TOOL_NAME>
  • Pipe output with jq for better readability: composio tools execute TOOL_NAME -d '{}' | jq
  • Set COMPOSIO_API_KEY as an environment variable for CI/CD pipelines
  • Use composio dev logs tools to inspect execution logs and debug issues

Next Steps

  • Try asking your coding agent to perform various Builtwith 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

FAQ

What is the Composio Universal CLI?

The Composio Universal CLI is a single command-line interface that lets coding agents and developers interact with 850+ 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.
