What list_channel_members does on Huly
AI agents call list_channel_members to retrieve information from Huly without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_channel_members is rated Low
This tool performs data retrieval from a channel to list its members. It has no capability to modify, delete, or execute operations. The information returned (member UUIDs and display names) is metadata about channel membership, not sensitive operational data. Blast radius of misuse is minimal—an AI agent could retrieve member lists but cannot modify access or perform harmful actions through this tool alone.
From the tool's definition Tool description explicitly states 'List members' and 'Returns' member information, indicating a retrieval-only operation with no modification or side effects. Returns account UUIDs and workspace display names.
Attacks that exploit this kind of access
The rule that runs list_channel_members safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Huly, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_channel_members, this is the rule to start with:
list_channel_members is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Huly, apply this rule, and every list_channel_members call is checked against it from then on.
