Cloudflare Gateway now detects Model Context Protocol traffic via protocol-level heuristics to expose shadow MCP usage and enforce approved-server access.
Cloudflare Gateway identifies Model Context Protocol (MCP) requests using protocol-level heuristics. Security teams can use the signal to discover shadow MCP traffic on managed networks, enforce Portal-only access for approved MCP servers, and block direct connections. The updates extend standard gateway and zero-trust controls to AI agent traffic.
