}About this server
OpenAI is listed in the AI & Machine Learning category of the MCPNav directory. It is distributed as npm and can be loaded by any client that speaks the Model Context Protocol.
Typical uses include giving your assistant scoped access to the corresponding service so it can answer questions and take actions with real data instead of guessing. Always review what a server can access before you enable it — see our MCP security guide.
