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
