Mac Developer Bridge is an open-source Model Context Protocol (MCP) tool designed to connect ChatGPT directly to your Mac's terminal. Created by Alexander Benz, the bridge establishes a workflow where ChatGPT operates as the high-level reasoning layer, while your local macOS machine serves as the native execution environment.

By bridging ChatGPT with your actual Mac setup, the tool enables the AI to interact directly with your system. Key capabilities include executing shell commands, managing files, running real PTY sessions, controlling background jobs, and accessing read-only Codex history.

Released under the MIT license, Mac Developer Bridge is intentionally not sandboxed, providing full terminal power directly to the AI model without restrictive isolation boundaries.
