dagger · dagger/container-use
Enables coding agents to work safely in isolated, parallel container environments using Dagger.
Development environments for coding agents. Enable multiple agents to work safely and independently with your preferred stack.
Preview
What you can do with it
- Run multiple agents on separate git branches without local file conflicts
- Review agent changes in a clean sandbox before merging to main code
- Take control of an agent's work by dropping into its specific terminal session
Safety check
Usable, but read the notes first.
- ●Installer downloads a remote script and pipes it to the shell.

container-use 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 checkoutto review any agent's work. - 🌎 Universal Compatibility: Works with any agent, model, or infrastructure - no vendor lock-in.
🦺 This project is in early development and actively evolving. Submit issues and/or reach out to us on Discord in the #container-use channel.
Quick Start
Install
# macOS (recommended)
brew install dagger/tap/container-use
# All platforms
curl -fsSL https://raw.githubusercontent.com/dagger/container-use/main/install.sh | bash
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:
# Add Container Use MCP server
cd /path/to/repository
claude mcp add container-use -- container-use stdio
# Add agent rules (optional)
curl https://raw.githubusercontent.com/dagger/container-use/main/rules/agent.md >> CLAUDE.md
💡 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!
