Docker and anthropic launch official AI sandboxes, but dev still publishes fix because big tech can't hide API keys without a custom docker hack

A developer has created an AI sandbox environment, dubbed AI Sandbox + DockMCP, to isolate AI systems and protect sensitive data. The project was motivated by a discovery that Claude Code's AI was silently reading API keys from an iOS project. Although official AI sandbox solutions have been released by Docker and Anthropic, the developer decided to publish their own project, which addresses specific gaps in the existing solutions. AI Sandbox + DockMCP uses Docker container isolation and provides controlled access to other containers through the Model Context Protocol. It also includes automatic validation and masking of secrets, making it a complementary solution to the official ones. The project is available on GitHub as a template repository, allowing users to easily integrate it into their own projects. By filling the gap between isolation and usability, AI Sandbox + DockMCP enables developers to work with AI in multi-container setups while keeping sensitive data secure.
