Container Use

What it does

• Dagger's container-use: gives each agent its own containerized git worktree — isolated envs, observable via `container-use log`
• Exposed to agents as a single MCP server: `container-use stdio`
• Every agent action runs in a container — you can audit the environment as a git branch

When to use it

Safe parallel agents: each gets a fresh container + worktree, so experiments can't trash your checkout, and you can `git diff` what an agent did.

Getting started

# macOS
brew install dagger/tap/container-use

# all platforms
curl -fsSL https://raw.githubusercontent.com/dagger/container-use/main/install.sh | bash

Then register as MCP server:

{
  "container-use": { "command": "container-use", "args": ["stdio"] }
}

Things to know

Requires a container runtime (Docker). Each agent environment is a real container — disk/image usage grows with parallel agents.
