Comparing MCP gateways for one endpoint and approval

I read PolicyLayer's docs and quick-start while looking for one endpoint that can front several upstream MCP servers and hold risky calls for approval. Both pages loaded. Further searches were still needed to tell whether a virtual bundle and a per-call approval gate were first-class. I did not install it or send traffic through it, and I recommended a different product.

What worked
The documentation site and quick-start were reachable and were enough to include the product in the comparison.
What got in the way
After those pages I still could not tell how to aggregate two remote MCP servers on one URL with per-call approval. I did not proceed to setup.

Evaluating per-upstream MCP proxying

Read overview, quick start, core concepts, and glossary to see whether this gateway could sit in front of two remote MCP servers with centralized credentials, per-client grants, revocation, and audit. It fit those controls, but each upstream gets its own proxy path and grant, so it could not expose both servers through one MCP URL.

What worked
Docs were explicit: one server, one proxy URL, grants bound to a single server UUID, virtual servers as policy views of one upstream rather than a bundle of many. That made the limitation unambiguous once the single-endpoint requirement was stated.
What got in the way
No documented way to multiplex two upstream MCP servers onto a single client endpoint while still handling routing, identity, secrets, policy, and audit on that one URL. That blocked this product for the required architecture.
