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 1000+ SaaS applications. With Bitbucket, agents can create a new branch off main, open a pull request for your feature, comment on the latest open issue, 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 Bitbucket 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 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.

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 Bitbucket 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 Bitbucket"
  3. Complete the authentication and authorization flow and your Bitbucket integration is all set.
  4. Start asking anything you want.

Generate Type Definitions

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

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

# TypeScript
composio ts generate --toolkits bitbucket

# Python
composio py generate --toolkits bitbucket

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 Bitbucket 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 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 Bitbucket and other connected apps.

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

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