chatgpt-mcp

chatgpt-mcp is an MCP (Model Context Protocol) server for macOS that lets MCP-compatible AI assistants send prompts to the ChatGPT desktop app and retrieve responses. It uses Python/FastMCP and automates interaction with the local desktop app (and notes limited language support).

Secret Handling

No network/TLS model is described because this is a local MCP server controlling a desktop app. Authentication/authorization and secret handling are not clearly documented. Use of pyautogui implies GUI automation risks (unintended interactions if the UI state changes).

Best When

You have a macOS machine with the ChatGPT desktop app running, and you want MCP tool access from an MCP-compatible client to drive ChatGPT through that desktop UI.

Avoid When

You need robust multilingual text input, headless/server execution, or strong guarantees around deterministic automation and error recovery.

Use Cases

• Integrate an MCP client (e.g., Claude Code) with the local ChatGPT desktop app via standard MCP tools
• Automate sending prompts and retrieving responses without writing a custom UI/automation bridge
• Enable chat workflow start/new chat plus subsequent message/response retrieval from an MCP agent

Not For

• Production-grade, server-to-server API access to ChatGPT (it depends on local macOS desktop app automation)
• Non-English input scenarios (README indicates Korean/other languages may not work reliably, with only English text input supported)
• Environments where GUI automation is disallowed or unreliable (the package depends on pyautogui)

Authentication

OAuth: No Scopes: No

No explicit authentication mechanism is described for the MCP server; it appears to rely on local execution and operating the user’s installed ChatGPT desktop app.

Pricing

Free tier: No

Requires CC: No

The repository indicates an MIT-licensed open-source MCP server; no pricing details are provided for using the server itself.

Known Gotchas

⚠ Depends on the ChatGPT macOS desktop app being installed and running
⚠ Likely relies on GUI/automation timing; transient UI issues may cause failed tool calls
⚠ README notes English text input only; other languages may not work properly

Alternatives

Use official ChatGPT APIs (when available for your use case) instead of desktop UI automation Other MCP servers that provide direct model/provider access rather than local UI automation A custom integration that uses a stable API surface (if you have one) instead of pyautogui-based control
