IntegrationsBuild

Turn any API into a tool with an OpenAPI file

Upload an OpenAPI file and pick which endpoints only read and which must ask first. Two minutes, no code.

Capstan has 120 integrations. Your own backend isn't one of them, so now you can add it.

Upload an OpenAPI file or point Capstan at its URL. Every endpoint becomes a tool, marked read-only or asks-first by its method: GET reads, everything else asks. Change any of them before you save.

Custom tools are on Team, Business and Enterprise.
