WHAT IT DOES

What addRuleToGroup does on Whistle

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

RISK

Why addRuleToGroup is rated Medium

This tool creates or modifies a relationship between a rule and a group in the Whistle proxy system. It is reversible (rules can be removed from groups via deleteRule or similar operations), making it a Write operation rather than Destructive.

From the tool's definition Tool name 'addRuleToGroup' and description '将规则添加到分组' (add rule to group) performs a modification operation that adds/associates a rule to an existing group within the Whistle proxy management system.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs addRuleToGroup safely

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

addRuleToGroup Rate-limited

addRuleToGroup 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.
