How are you handling auth with an MCP gateway?

The main benefit we found was having one place to manage authentication, authorization, and audit logs. Short-lived credentials between the gateway and upstream servers can also reduce the spread of long-lived secrets. It helps to treat the gateway as a security boundary, not a plug-and-play fix for every server’s quirks.

For us, the hard part was keeping connections healthy, not scaling the number of servers. A gateway can tidy up access, but it does not automatically solve connection lifecycle issues. I’d start with a small set of servers and make reconnects, timeouts, and failure handling visible before expanding.

Centralizing auth is useful once per-server credentials become a chore. Just be careful not to turn the gateway into one fragile box with broad access. Keep upstream credentials separated, limit what each route can reach, and have a plan for token refresh and gateway recovery. The integration details can take longer than deploying the gateway itself.

Expect rough edges. Some servers may handle tokens differently, so a gateway can mean custom configuration or compatibility work rather than a clean, uniform auth setup. I’d test your actual identity and token flows end to end before relying on it for production access.
