Pattern: Enterprise MCP Governance Crystallizes — SSO Gating and Opt-In Defaults Become Table Stakes
Cloudflare Blog·medium signal
Cloudflare's enterprise MCP architecture and IP Fabric's opt-in-by-default MCP server (both April 2026) establish a governance pattern: enterprise MCP deployments gate tool access behind SSO/MFA, enforce DLP rules on tool outputs, require explicit opt-in rather than ambient availability, and centralize discovery through server portals. This mirrors how enterprises adopted REST APIs a decade ago — the protocol is open, but production deployment demands an access control layer.
