dagger/container-use

What it solves

Coding agents often struggle to work safely and independently without interfering with the user's local environment or each other. Container Use provides isolated, parallel environments for these agents, allowing users to run multiple agents simultaneously without conflicts and without having to "babysit" each one.

How it works

It is an open-source Model Context Protocol (MCP) server that functions as a CLI tool. Powered by Dagger, it creates a fresh container for each agent, typically tied to its own git branch. This allows agents to work in isolation, while the user can review their work by simply checking out the corresponding git branch.

Who it’s for

Developers using MCP-compatible coding agents (such as Claude Code, Cursor, or Goose) who want to scale their agentic workflows by running multiple agents in parallel across different branches.

Highlights

• Isolated Environments: Each agent operates in its own container and git branch to prevent conflicts.
• Real-time Visibility: Provides complete command history and logs of agent actions.
• Direct Intervention: Users can drop into an agent's terminal to take control if the agent gets stuck.
• Universal Compatibility: Works with any MCP-compatible agent, model, or infrastructure.
• Git-based Workflow: Review agent work using standard git checkout commands.
