WHAT IT DOES

What list_task_types does on Huly

AI agents call list_task_types 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_task_types is rated Low

This tool retrieves and queries task type definitions and their properties without creating, modifying, or deleting data. It has no side effects beyond returning information, making it a standard Read operation. The low severity reflects minimal risk even if misused by an agent—it only exposes task type metadata that is typically non-sensitive project configuration.

From the tool's definition Tool name is 'list_task_types' and description states it 'List[s] Huly issue/task types' with optional filtering and returns metadata (identity, parent project type, kind, issue class, status count).

RECOMMENDED RULE

The rule that runs list_task_types 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_task_types, this is the rule to start with:

list_task_types Allowed

list_task_types 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_task_types": {}
  }
}

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_task_types call is checked against it from then on.
