WHAT IT DOES

What add_card_comment does on Huly

AI agents use add_card_comment 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 add_card_comment is rated Medium

This tool creates a comment on a card in Huly, which is a write operation that modifies card data by adding a new child record. The operation is reversible (comments can typically be deleted), so it does not qualify as Destructive.

From the tool's definition add_card_comment: 'Add a markdown comment to one Huly card' — creates a new comment object attached to a card, a reversible modification of data.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

add_card_comment Rate-limited

add_card_comment 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.
