Frequently Asked Questions

What is the primary function of an MCP Gateway in 2026?

An MCP gateway sits between AI clients such as Claude, ChatGPT, Cursor, Gemini, and Copilot and MCP servers, providing centralized authentication, rate limiting, and audit logging. The gateway transforms local MCP deployments into production-grade infrastructure with enterprise security controls and governance capabilities.

How does rate limiting protect enterprise AI systems?

Rate limiting prevents resource exhaustion, controls costs, and ensures fair usage across teams. Advanced gateways can implement per-tool, per-user, and per-team limits with low-overhead enforcement. Without rate limiting, a single runaway AI agent could consume excessive resources or trigger API overage charges.

What compliance standards should an enterprise look for in an MCP Gateway?

SOC 2 Type II audited posture provides strong third-party validation of security controls. For healthcare and EU environments, prioritize gateways with audit trails, role-based access control, encryption, enterprise SSO, and documented compliance support. MintMCP is SOC 2 Type II audited, compliant with HIPAA standards, and signs BAAs for customers handling protected health information.

Can MCP Gateways integrate with existing enterprise security infrastructure?

Most enterprise-grade gateways support OAuth 2.0, SAML, and SSO integration with identity providers like Okta, Microsoft Entra (Azure AD), and Ping Identity. Solutions that extend existing API gateway infrastructure preserve security investments while adding MCP governance capabilities.

How do MCP Gateways address the 'shadow AI' challenge?

Without governance, teams deploy AI tools that operate as black boxes with significant security risks: zero telemetry, no request history, and uncontrolled access. MCP gateways provide centralized visibility and policy enforcement, turning shadow AI into sanctioned AI without disrupting developer workflows.
