WHAT IT DOES

What list_mentions does on Huly

AI agents call list_mentions 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_mentions is rated Low

This tool retrieves historical mention data about the current user from activity messages. It performs no creation, modification, deletion, or execution of external operations. The blast radius of misuse is minimal—an agent could only retrieve mention history that the user would have access to anyway. This is a low-severity read operation.

From the tool's definition Tool name 'list_mentions' with description 'List @mentions of the current user in activity messages' indicates a retrieval operation.

RECOMMENDED RULE

The rule that runs list_mentions 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_mentions, this is the rule to start with:

list_mentions Allowed

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

View as policy code

policy.json

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

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_mentions call is checked against it from then on.
