OpenAI Unveils Secure MCP Tunnel for Enterprise Data Privacy
OpenAI has introduced the Secure MCP Tunnel, which may let companies keep their Model Context Protocol servers inside their own networks while still using tools like ChatGPT and Codex. The tunnel uses outbound-only HTTPS connections, so companies do not have to change inbound firewall rules. The security setup appears to lower risk by avoiding open ports and using cloud IAM roles instead of long-lived API keys. There is no confirmation yet of formal security certifications, so compliance might depend on how companies set up their own security controls. Early use seems to be for secure data access and automation inside companies, but exact adoption numbers are not available.
