Mastro Connect

Mastro Connect is a command-line tool that captures your browser session of web apps, describes the app's API with OpenAPI 3.1, and allows you to drive the app directly from the terminal. It uses a browser extension to securely capture session data locally, then generates CLI commands to interact with the API, enabling faster, more reliable automation than browser click automation. It supports multi-step workflows, agent skills, and connectors defined as data, not code.
