Codex Bridge connects OpenAI's Codex CLI to MiraBridge, enabling mobile monitoring and control of Codex sessions.
What It Does
The bridge is a bidirectional protocol translator that runs alongside Codex CLI on your machine:
Mobile -> Gateway (WebSocket) -> Codex Bridge -> Codex App Server -> Codex CLI
It translates between MiraBridge's WebSocket protocol and Codex's JSON-RPC 2.0 protocol.
