Nine vendors inject the key. Three things are still empty
Server-side injection is table stakes, and thirteen of the fifteen vendors in our survey have it. Three things were missing everywhere. Per-call human approval next to that injection. A journal you can verify without the vendor. MCP with arbitrary HTTP and SSH through one broker. Every page below says where the other side is stronger, because a comparison that loses on nothing is an advertisement.
The six worth reading
- Sallyport and AembitThe category leader on distribution, with no human in the loop at all.
- Sallyport and DelineaThe closest description of our shape, sold the way enterprise software is sold.
- Sallyport and BritivePer-call approval for MCP tool calls, and only for MCP tool calls.
- Sallyport and Auth0 Token VaultA vault that hands the token to your code, which is the pattern the MCP specification refuses.
- Sallyport and ArcadeA tool platform with authorization built in, and the raw token inside the tool.
- Sallyport and InfisicalOpen source, a public price, and approval at the session rather than the call.
