MCP gateway vs MCP proxy: Do you need one?

An MCP gateway acts as a centralized service that manages authentication, authorization, routing, and audit logging between AI agents and MCP servers, providing a streamlined entry point for agent-to-tool traffic. Unlike an MCP proxy, which merely handles transport bridging and server aggregation without a policy layer, an MCP gateway enforces identity and policy, making it suitable for environments with multiple clients and servers requiring consistent governance and compliance, especially in cases involving per-user or per-tenant access isolation. Although the MCP specification does not include a gateway, vendors have implemented various versions, with capabilities varying from simple logging registries to comprehensive tool-level authorization systems. An MCP gateway is beneficial when managing numerous clients and servers with diverse access policies, but it introduces additional latency and maintenance as a trade-off for centralized control and audit capabilities. It is not necessary for simpler environments where direct connections or thin proxies suffice, such as when a single team manages a limited number of MCP servers. Products like Nango complement an MCP gateway by providing integration infrastructure, allowing agents to connect to a wide range of APIs with customizable tools, further enhancing the capabilities of an MCP setup.
