Summary

Cloudflare Gateway now detects Model Context Protocol (MCP) traffic using protocol-level heuristics, giving security teams a signal to find shadow MCP usage and control access to approved servers.

Key facts

Cloudflare Gateway identifies MCP requests through protocol-level heuristics.
Security teams can use the signal to find shadow MCP traffic.
Teams can enforce Portal-only access for approved MCP servers.
Direct connections can be blocked on managed network paths.

Why it matters

Builders and buyers deploying MCP servers gain a way to discover unapproved MCP traffic and restrict access to approved servers, rather than leaving those connections unmonitored on managed networks.
