22## Installation
23 
24First, make sure you've got the [Claude Desktop app](https://claude.ai/download) installed and you've requested an [OpenAI API key](https://platform.openai.com/api-keys).
25 
26Add this entry to your `claude_desktop_config.json` (on Mac, you'll find it at `~/Library/Application\ Support/Claude/claude_desktop_config.json`):
27 
28```json
29{
30  "mcpServers": {
31    "mcp-openai": {
32      "command": "npx",
33      "args": ["-y", "@mzxrai/mcp-openai@latest"],
34      "env": {
35        "OPENAI_API_KEY": "your-api-key-here (get one from https://platform.openai.com/api-keys)"
36      }
37    }
38  }
39}
40```
41 
42This config lets Claude Desktop fire up the OpenAI MCP server whenever you need it.
