About
Postman Agent is a micro-application that runs locally on your Mac. It overcomes the Cross-Origin Resource Sharing (CORS) limitations of browsers and facilitates sending API requests from the browser version of Postman.
If you use Postman for Web, you also need to download the Postman desktop agent. The Mac version is available for macOS 11 (Big Sur) and later, with builds for both Intel and Apple chips.
To learn more, read the Introducing the Postman Agent blog post or the installation docs. If you want to connect a coding agent such as Claude, Cursor, or Codex, the website points to the Postman CLI instead.
