WHAT IT DOES

What update_card does on Huly

AI agents use update_card 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_card is rated Medium

This tool creates or modifies data reversibly. It updates card fields in a project management system, which is a typical Write operation. The changes are reversible (can be edited again), and the tool does not delete or destroy data (which would make it Destructive), nor does it trigger arbitrary code execution (which would make it Execute).

From the tool's definition Tool name 'update_card' and description 'Update fields on an existing Huly card. Only provided fields are modified.' — modifies existing data reversibly without deletion or destruction.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

update_card Rate-limited

update_card 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.
