WHAT IT DOES

What list_activity does on Huly

AI agents call list_activity 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.

RISK

Why list_activity is rated Low

This tool retrieves and queries historical activity/audit log data for objects in Huly. It performs a read-only operation with no ability to create, modify, delete, or execute operations. The low severity reflects minimal risk even if misused by an AI agent, as it only exposes read access to activity history.

From the tool's definition Tool name is 'list_activity' and description states it 'List activity messages' and 'Returns activity sorted by date'. The verb 'list' and 'returns' indicate data retrieval with no modification or side effects.

RECOMMENDED RULE

The rule that runs list_activity 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_activity, this is the rule to start with:

list_activity Allowed

list_activity is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_activity": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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