What is MCP OpenAI Server?

MCP OpenAI Server is a Model Context Protocol (MCP) server that integrates OpenAI’s chat models directly into Claude. It is built for users of Claude Desktop who want to tap into OpenAI’s models (gpt-4o, gpt-4o-mini, o1-preview, o1-mini) from within the same interface.

How to use MCP OpenAI Server?

Install the Claude Desktop app, obtain an OpenAI API key, then add the provided JSON entry to your claude_desktop_config.json file. Once configured, simply ask Claude to query an OpenAI model—for example, “Can you ask o1 what it thinks about this problem?”—and the server handles the rest.
