Container use: MCP server, setup and security
Container use is an open-source MCP server published on GitHub that lets an AI agent code in a fresh container and git branch with terminal access. Its repository has 4,079 stars and its last commit is from September 21, 2026 and it is licensed under Apache-2.0.
What Container use does
According to its repository: “Containerized environments for coding agents: each agent works in its own fresh container and git branch, with execution history and terminal access.”
The Model Context Protocol (MCP) is a standard plug between an AI agent and an outside service: once the server is connected, its tools show up in the agent, which decides when to call them. Container use is listed under Code execution, a category of 32 servers in the directory, where it ranks #1 by stars.
Installing and connecting Container use
No package or remote server is declared in the official MCP registry: you install it from source, following the repository README.
It works with any MCP-compatible client (Claude Desktop, Claude Code, Cursor, VS Code, Codex and most recent agents). You add one entry to the client's MCP configuration: server name, start command or URL, environment variables. Project language: Go. Listed systems: macOS, Windows, Linux.
Security: what to check
Connecting an MCP server means installing software that talks straight to your agent: it runs with your rights and the model trusts its tool descriptions. The risk therefore depends on what it can touch and how far its code can be trusted.
Points found for Container use:
- System access: the Code execution category gives the agent control over files, a terminal, code or a browser. A booby-trapped instruction in content the agent reads (prompt injection) can then turn into an action.
Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.
Project activity and maintenance
Created on May 23, 2025, the dagger/container-use repository has 4,079 stars and 212 forks, with 47 open issues. It has more stars than 97% of the servers in the directory. Last change 1 month ago.
Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
Verdict
Container use is one of the most solid servers in its category: followed, maintained and well framed.
