Scaling MCP adoption: Our reference architecture for simpler, safer and cheaper enterprise deployments of MCP

Cloudflare describes a reference architecture and operational best practices to secure enterprise deployments of the Model Context Protocol (MCP). The post covers centralizing remote MCP servers, integrating Cloudflare Access for authentication, MCP server portals for discovery and governance, Code Mode to reduce token/context costs, AI Gateway for LLM provider switching and cost controls, and Cloudflare Gateway/DLP and WAF rules (including regex patterns) to detect or block unauthorized or malicious MCP usage. The content is prescriptive guidance for defenders rather than a report of an active incident.
