CF-Incidents Gateway, Cloudflare One - MCP protocol detection and AI Security dashboard

[ENF News Bot]

Cloudflare Gateway now automatically detects Model Context Protocol (MCP) ↗︎ traffic flowing through your network. MCP is the standard protocol used by AI agents to connect to external tools and data sources. Gateway identifies MCP requests by inspecting protocol-specific headers and payload characteristics.

MCP policy selector​

A new Is MCP selector (experimental.is_mcp) is available in HTTP policies. Use this selector to build Gateway rules that allow, block, or isolate MCP traffic.

This selector is currently in beta and may change before general availability.

For example, the following policy blocks MCP traffic that does not arrive through an approved MCP portal:

Selector	Operator	Value	Logic	Action
Is MCP	is	True	And	Block
Traffic Source	is not	MCP portal
