MCP OpenAI Server

A Model Context Protocol (MCP) server that lets you seamlessly use OpenAI's models right from Claude.

Features

  • Direct integration with OpenAI's chat models
  • Support for multiple models including:
    • gpt-4o
    • gpt-4o-mini
    • o1-preview
    • o1-mini
  • Simple message passing interface
  • Basic error handling

Prerequisites

Installation

First, make sure you've got the Claude Desktop app installed and you've requested an OpenAI API key.

Add this entry to your claude_desktop_config.json (on Mac, you'll find it at ~/Library/Application\ Support/Claude/claude_desktop_config.json):

{ "mcpServers": { "mcp-openai": { "command": "npx", "args": ["-y", "@mzxrai/mcp-openai@latest"], "env": { "OPENAI_API_KEY": "your-api-key-here (get one from https://platform.openai.com/api-keys)" } } } }

This config lets Claude Desktop fire up the OpenAI MCP server whenever you need it.

Usage

Just start chatting with Claude and when you want to use OpenAI's models, ask Claude to use them.

For example, you can say,

Can you ask o1 what it thinks about this problem?

or,

What does gpt-4o think about this?

The server currently supports these models:

  • gpt-4o (default)
  • gpt-4o-mini
  • o1-preview
  • o1-mini

Tools

  1. openai_chat
    • Sends messages to OpenAI's chat completion API
    • Arguments:
      • messages: Array of messages (required)
      • model: Which model to use (optional, defaults to gpt-4o)

Problems

This is alpha software, so may have bugs. If you have an issue, check Claude Desktop's MCP logs:

tail -n 20 -f ~/Library/Logs/Claude/mcp*.log
