WHAT IT DOES

What update_status_category does on Huly

AI agents use update_status_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 update_status_category is rated Medium

This tool modifies status category metadata (updating by ID or label) but does not delete data, execute arbitrary code, or move money. The constraint that 'the resulting default status must belong to the resulting attribute' suggests structural validation rather than destructive operations.

From the tool's definition Tool name contains 'update' and description states 'Update a generic StatusCategory by ID or exact label', indicating modification of existing data without deletion or execution of code.

RECOMMENDED RULE

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

update_status_category Rate-limited

update_status_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.

Register the Huly MCP server in PolicyLayer and add a rule for update_status_category: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Huly. Nothing to install.

What risk level is update_status_category? +

update_status_category is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

How do I block update_status_category completely? +
