OpenAI has released Secure MCP Tunnel, an enterprise feature enabling supported products—ChatGPT web, Codex, Responses API, and AgentKit—to connect to private or on-premises MCP servers via a customer-hosted tunnel client without exposing those servers to the public internet. The feature addresses a key enterprise adoption barrier by allowing MCP-based tool integrations to remain within private network boundaries. This is a meaningful infrastructure addition for organizations deploying AI agents against internal systems.
