WHAT IT DOES

What wavexis_capture_har does on Wavexis

AI agents call wavexis_capture_har to retrieve information from Wavexis without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why wavexis_capture_har is rated Low

This tool captures/records network traffic data (HAR format) during a page load. It is a read/observation operation — it retrieves network request/response metadata without modifying data. However, it can expose sensitive information like auth tokens, cookies, and API responses captured in the HAR, hence medium severity.
