WHAT IT DOES

What update_schedule does on Huly

AI agents use update_schedule 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_schedule is rated Medium

This tool creates or modifies data (calendar schedule attributes) in a reversible manner. The operation updates calendar metadata rather than executing external code or triggering irreversible deletions. While it could affect multiple calendar properties and potentially impact scheduling visibility, the changes are reversible through subsequent updates.

From the tool's definition Tool description explicitly states 'Update a calendar schedule' with modifiable fields including owner, title, description, duration, interval, availability, timeZone, and calendar move operations.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

update_schedule Rate-limited

update_schedule 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.
