README

ChatGPT MCP Server

An MCP (Model Context Protocol) server providing a tool to interact with the ChatGPT macOS desktop application.

Overview

This server exposes a single tool, `chatgpt`, designed to allow MCP clients (e.g., Cline, Claude Desktop, Cursor) to send prompts to and retrieve conversation lists from the native ChatGPT application on macOS.

Problem Solved

AI models interacting via MCP often need to leverage the capabilities or context within specific desktop applications like ChatGPT. Directly controlling the application allows the AI to continue existing conversations, ask new questions within the user's established ChatGPT environment, or query the conversation history without manual copy-pasting or context switching by the user.

Solution: The `chatgpt` Tool

This server provides the `chatgpt` tool with the following operations:

**Operation:** `ask`
- Description: Sends a prompt to the ChatGPT application. Can optionally continue an existing conversation.
- Input Parameters:
  - prompt (string, required): The text prompt to send.
  - conversation_id (string, optional): The title/ID of an existing conversation to continue. If omitted, uses the currently active chat.
  - time_to_wait (number, optional, default: 6): The time in seconds (0-3600) to wait after sending the prompt before attempting to retrieve the response text from the ChatGPT window.
    - If time_to_wait > 0: The tool waits for the specified duration and then returns the text content found in the main response area of the ChatGPT window.
    - If time_to_wait == 0: The tool sends the prompt and immediately returns a confirmation message ("Prompt sent. Response retrieval skipped (time_to_wait was 0).") without waiting or attempting to read the response.
**Operation:** `get_conversations`
- Description: Retrieves the list of conversation titles from the ChatGPT application's sidebar.
