WHAT IT DOES

What create_tag_category does on Huly

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

RISK

Why create_tag_category is rated Medium

This tool creates metadata (tag/label categories) rather than retrieving data (Read), doesn't directly execute arbitrary operations (Execute), and is reversible/not permanent (not Destructive). The idempotent design confirms it only creates or returns existing data without side effects. Creating categories is a standard data modification action with low blast radius in the context of a project management system.

From the tool's definition Tool description states it 'Create[s] a new tag/label category' and is marked as 'Idempotent: returns existing category if one with the same label and targetClass already exists'.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

create_tag_category Rate-limited

create_tag_category 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.

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