network_enable_intercept · Js Reverse MCP: Risk & Policy

WHAT IT DOES

What network_enable_intercept does on Js Reverse

AI agents invoke network_enable_intercept to trigger actions in Js Reverse. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why network_enable_intercept needs a policy

This tool actively enables interception of network traffic within the browser, triggering an external operation that monitors and captures live HTTP requests including sensitive login traffic. It is not a passive read — it changes the browser's runtime state to intercept communications, making it an Execute-category action. Misuse could expose credentials and sensitive session data, warranting high severity.

From the tool's definition 开启网络请求拦截，捕获所有HTTP请求（特别是登录请求） — 'enables network request interception, capturing all HTTP requests (especially login requests)'
