WHAT IT DOES

What wavexis_set_pref does on Wavexis

AI agents use wavexis_set_pref to create or update resources in Wavexis, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Wavexis environment.

RISK

Why wavexis_set_pref is rated Medium

This tool modifies browser state (preferences) reversibly. It is not destructive (preferences can be changed back), not financial, and not a direct code execution—it configures browser behavior. While it could affect browsing behavior or security posture if misused (e.g., disabling security warnings), the action itself is Write-category.

From the tool's definition Tool name 'wavexis_set_pref' and description 'Set a browser preference value' indicate modification of browser settings/configuration. The verb 'Set' and the operation of changing preference values are characteristic of Write operations.

RECOMMENDED RULE

The rule that runs wavexis_set_pref safely

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

wavexis_set_pref Rate-limited

wavexis_set_pref stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
