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 Google BigQuery, agents can run yesterday's sales summary query, find top 10 customers by revenue, analyze traffic data for last quarter, 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 Google BigQuery 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 Google BigQuery 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 Google BigQuery"
  3. Complete the authentication and authorization flow and your Google BigQuery integration is all set.
  4. Start asking anything you want.

Supported Tools & Triggers

Tools
QueryQuery tool will run a sql query in bigquery.

Universal CLI Commands for Google BigQuery

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

Connect your Google BigQuery account

Link your Google BigQuery account and verify the connection:

bash
# Connect your Google BigQuery account (opens OAuth flow)
composio connected-accounts link googlebigquery

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

Discover Google BigQuery tools

Search and inspect available Google BigQuery tools:

bash
# List all available Google BigQuery tools
composio tools list --toolkit googlebigquery

# Search for Google BigQuery tools by action
composio tools search "google bigquery"

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

Common Google BigQuery Actions

Query — Query tool will run a sql query in bigquery

bash
composio tools execute GOOGLEBIGQUERY_QUERY \
  --query "<string>"

Generate Type Definitions

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

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

# TypeScript
composio ts generate --toolkits googlebigquery

# Python
composio py generate --toolkits googlebigquery

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 Google BigQuery 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 Google BigQuery and other connected apps.

How is the CLI different from using an MCP server for Google BigQuery?

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 Google BigQuery 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 Google BigQuery data and credentials are handled as safely as possible. You can also bring your own OAuth credentials for full control.
