PyBurp

Summary: PyBurp is a Burp Suite extension, authored by cyal1 and listed at version 1.0.2, that provides predefined Python functions for modifying HTTP and WebSocket traffic, registering context menus, processing Intruder payloads, running passive and active scans, and interacting with Collaborator. The extension also allows direct access to the Montoya API from Python scripts, and PortSwigger notes that extensions are written by third-party users and come with no warranty of quality or usefulness.

Bottom line: This is third-party code running inside the tool your testers use to intercept and modify live traffic, and PortSwigger explicitly makes no warranty about its quality or usefulness - so the extension's access to the Montoya API is a supply-chain decision, not a convenience one.
