MCP Gateway Threshold Rule: Every Team Running 5+ MCP Servers in Production Uses a Gateway
Integrate.io's analysis of MCP production deployments found that a gateway isn't optional past 3 servers—every team analyzed running 5+ MCP servers uses some form of gateway or proxy for centralized auth, routing, and observability. Best practices: use OAuth 2.0/OIDC with enterprise identity providers, never store credentials in MCP config files (use env vars or secrets manager), enforce TLS 1.2+ with mutual TLS for service-to-service trust, and implement RBAC with least-privilege per-tool permissions. MintMCP achieved the industry's first SOC 2 Type II certification for an MCP platform.
