API Development MCP servers on mcprush, filed under one heading so the shelf can be read in one pass.
Every server here names the publisher behind it and whether that publisher has been verified, the runtime it uses, how it authenticates, the tool surface it exposes and the price model it is sold under — and where a security scan has been run against it, what the scan found. The filters on the left narrow it further and the sort at the top decides what comes first.
A server that runs on its publisher’s infrastructure is reached through the mcprush gateway, so one key covers everything installed against your account, the calls are metered where you can see them and the ceiling on what they may cost is yours to set. Installing one is a line of the mcprush CLI — npx mcprush@latest add, followed by the server’s id — and a --client flag writes another client’s config instead of the default one. A server that runs on your own machine carries its publisher’s own instructions instead, and the listing says which of the two it is before you install anything.
