WHAT IT DOES

What browser_go_back does on Looking Glass

AI agents invoke browser_go_back to trigger actions in Looking Glass. 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.

RISK

Why browser_go_back is rated High

Based on the name, this tool triggers a browser navigation action (going back in browser history), which constitutes an external operation. Since the description is empty, confidence is reduced, but browser navigation tools in this context (an AI-native browser for agents) are Execute-category actions. Severity is medium as navigating back could disrupt agent workflows or cause unintended state changes.

From the tool's definition Tool name 'browser_go_back' suggests a browser navigation action; description is empty and uninformative.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs browser_go_back safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Looking Glass, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For browser_go_back, this is the rule to start with:

browser_go_back Rate-limited

browser_go_back stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
