What MCP Traffic Detection Can—and Cannot—Protect

Intro

Where Cloudflare’s MCP traffic detection helps, where it cannot, and which controls still belong at the server.

Takeaways

  • Agent tool use changes the risk profile of normal permissions.
  • MCP messages use JSON-RPC.
  • The next step is tool-level risk classification.
