WHAT IT DOES

What update_component does on Huly

AI agents use update_component 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_component is rated Medium

This tool modifies existing data (component fields) reversibly. It does not delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or query data passively (Read). The ability to update component fields in a project management system carries medium severity due to potential for disruption to project state, but changes are reversible and scoped to a single component's fields.

From the tool's definition Tool name 'update_component' and description 'Update fields on an existing Huly component. Only provided fields are modified.' indicate modification of existing data without deletion or system-level code execution.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

update_component Rate-limited

update_component 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 update_component call is checked against it from then on.
