GPT Web Codex is an open-source Model Context Protocol (MCP) launcher that bridges ChatGPT Web conversations with local Luna task execution via codex exec --json. It allows ChatGPT in standard browsers to act as a planner while executing local terminal tasks, file manipulations, and code verification securely.

Technical Overview of GPT Web Codex

The software operates as a standalone runtime packaged with an embedded Bun engine or portable AppImage, eliminating mandatory system-wide installation. Rather than running persistent background resource drains, it spins up asynchronous, serialized tool processes and executes system shell commands directly on demand. It interfaces externally via OpenAI Tunnels while restricting local code modifications, ensuring local ~/.codex/config.toml files and default Codex routing configurations remain untouched.

Core Features of GPT Web Codex

  • Zero-telemetry execution isolates credentials in private local storage and never stores ChatGPT browser cookies, conversation histories, or user profiles.
  • Page-refresh recovery maintains inline image cards across web reloads using opaque browser IDs and a private 128-item local preview cache.
  • Strict attachment sandboxing verifies SHA-256 hashes and MIME types, importing conversation files directly to user-disclosed paths without auto-executing them.
  • Granular permission controls enforce explicit execution tiers including read-only, workspace-write, and danger-full-access modes for local operations.
  • Asynchronous process management keeps long-running terminal and Luna operations active during web disconnects, providing explicit status polling and job cancellation.

System Compatibility & Updates

GPT Web Codex provides verified support for Windows and Ubuntu 26.04 on x86_64 architectures, with macOS x86_64/ARM builds validated via automated continuous integration. The latest release introduces refresh-persistent image cards backed by an isolated local preview cache and non-FUSE extract-and-run support for Linux AppImages.

Why Choose GPT Web Codex?

It delivers local coding execution directly from your standard browser interface without employing brittle browser automation or intrusive configuration proxies. The fully auditable MIT-licensed codebase pairs local sandboxed safety with pure MCP tool bridging, giving developers complete authority over system access.
