browse_interact · Obscura MCP: Risk & Policy

WHAT IT DOES

What browse_interact does on Obscura MCP

AI agents invoke browse_interact to trigger actions in Obscura MCP. 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 browse_interact needs a policy

This tool executes browser actions (clicking elements, typing text) on live web pages, which constitutes external operation execution. Misuse could trigger unintended form submissions, button clicks, logins, purchases, or other side effects on arbitrary URLs. The anti-detection capability increases risk by making automated interactions harder to detect or block.

From the tool's definition 'Click an element or type text into a page' — triggers browser actions (click, type) on live web pages; 'One-shot: pass url' confirms it drives real browser interactions against external sites
