Why browser_navigate is rated High
Navigation is an external operation with effects that depend on the URL argument—it can load arbitrary web content, trigger requests, and cause side effects on remote systems. While not directly destructive or financial, it clearly executes an action rather than reading data. Confidence is high based on the function name and server context, though lowered slightly due to the empty description.
From the tool's definition Tool name 'browser_navigate' combined with server description 'AI-native browser for agents' indicates this tool triggers browser navigation actions.

browser_navigate 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Looking Glass, apply this rule, and every browser_navigate call is checked against it from then on.
