WHAT IT DOES

What create_on_call_policy does on OneUptime

AI agents use create_on_call_policy to create or update resources in OneUptime, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your OneUptime environment.

Parameter	Type	Required	Description
`name`	string	Yes	Any friendly name of this object.
`labels`	array	—	Relation to Labels Array where this object is categorized in.
`projectId`	string	—	ID of your OneUptime Project in which this object belongs.
`isArchived`	boolean	—	Archived on-call policies are hidden from the On-Call Policies list and page no one: incidents and alerts that use them skip them. Unarchiving puts them back in
`description`	string	—	Friendly description that will help you remember.
`customFields`	object	—	Custom Fields on this resource.
`acknowledgementTimeoutInMinutes`	number	—	Page again when something this policy paged about is acknowledged but not resolved within this many minutes (5 to 1440). Empty: never.
`repeatPolicyIfNoOneAcknowledges`	boolean	—	Repeat the policy if no one acknowledges the alert.
`repeatPolicyIfNoOneAcknowledgesNoOfTimes`	number	—	How many more times the policy starts again from its first escalation rule when nobody acknowledges: a whole number of 1 or more while Repeat Policy If No One A

RECOMMENDED RULE

The rule that runs create_on_call_policy safely

PolicyLayer is an MCP gateway: it sits between your AI agents and OneUptime, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_on_call_policy, this is the rule to start with:

create_on_call_policy Rate-limited

create_on_call_policy 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.
