Cloudflare DEX MCP Server 📡
This is a Model Context Protocol (MCP) server that supports remote MCP connections, with Cloudflare OAuth built-in.
It integrates tools powered by the Cloudflare DEX API to provide visibility into device, network, and application performance across your Zero Trust organization
The /mcp URL uses a stateless SDK v2 handler that creates a fresh server with request-scoped auth/account context for every request. The retired /sse URL returns 410 Gone pointing at /mcp. OAuth remains durable security state, and WarpDiagReader remains an application cache for downloaded diagnostics; no MCP protocol session is retained.
