Building a Multi-Tenant MCP Proxy: One Endpoint, Three Backends

Tue, 01 Sep 2026 09:00:00 -0400

This post is for platform and infrastructure leads wiring agents into real systems. You have a few MCP servers, more than one tenant who needs them, and you want a single endpoint in front of them. My position is that all of the tenancy belongs in the proxy and none of it belongs in the backends. The rest of this post covers the decisions that follow from that and the ones I would not compromise on.
