Postman Agent
Postman Agent is a small desktop companion for Postman on the web that lets your Mac send API requests to local and private networks.
What is Postman Agent?
Postman Agent is a local desktop helper for developers who use Postman in a web browser. It works with the Postman web app to send API requests from your Mac without the browser limitations that can block calls to local services or private network endpoints. This makes it useful for testing APIs running on localhost, internal development servers, staging systems, and other environments that are not directly reachable from a browser alone. The app is designed as a lightweight companion rather than a full API client, so people who want the complete Postman experience may use the main Postman desktop app instead. On macOS, users commonly encounter it when building, debugging, or validating APIs during web-based development workflows. Postdot Technologies, Inc publishes the software as part of the Postman ecosystem.
Key features
- Send API requests from the Postman web app through a local desktop agent
- Access localhost and private network endpoints while working in a browser
- Bypass browser CORS limitations for API testing workflows
- Support web-based API development without installing the full Postman desktop app

Safety overview
Status: Safe
This is legitimate developer software used to route API requests from the Postman web app through your Mac. Network access and background operation are normal for its purpose, and it may interact with local or private endpoints that you choose to test. Use it only with API environments you trust, and remember that requests sent through the agent can include headers, tokens, and other development data from your Postman workflow.
Recommendation: Keep Postman Agent if you use Postman in a web browser and need to work with localhost or private APIs. If you no longer use the web version of Postman, you can remove it without affecting unrelated apps, though browser-based Postman requests that rely on the agent may stop working.
