Containerized environments for coding agents. (📦🤖) (📦🤖) (📦🤖)
**Container Use** lets coding agents do their work in parallel environments without getting in your way. Go from babysitting one agent at a time to enabling multiple agents to work safely and independently with your preferred stack. See the full documentation.
It's an open-source MCP server that works as a CLI tool with Claude Code, Cursor, and other MCP-compatible agents. Powered by Dagger.
* 📦 **Isolated Environments**: Each agent gets a fresh container in its own git branch - run multiple agents without conflicts, experiment safely, discard failures instantly.
* 👀 **Real-time Visibility**: See complete command history and logs of what agents actually did, not just what they claim.
* 🚁 **Direct Intervention**: Drop into any agent's terminal to see their state and take control when they get stuck.
* 🎮 **Environment Control**: Standard git workflow - just git checkout to review any agent's work.
* 🌎 **Universal Compatibility**: Works with any agent, model, or infrastructure - no vendor lock-in.

Quick Start
Install
Setup with Your Agent
Container Use works with any MCP-compatible agent. The setup is always the same: **add container-use stdio as an MCP server**.
**👉 Complete setup guide for all agents (Cursor, Goose, VSCode, etc.)**
**Example with Claude Code:**
💡 Command Shortcut
The container-use command is also available as cu for convenience. Both commands work identically:
- container-use stdio (used in documentation)
- cu stdio (shortcut)
Try It
Ask your agent to create something:
> Create a hello world app in python using flask
Your agent will work in an isolated environment and give you URLs to view the app and explore the code!
