WHAT IT DOES

What create_alert_state_timeline does on OneUptime

AI agents use create_alert_state_timeline 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
`endsAt`	object	—	When did this status change end?
`alertId`	string	Yes	Relation to Alert ID in which this resource belongs.
`startsAt`	object	—	When did this status change? Correct this when the recorded time is wrong - every measurement derived from this timeline is recomputed from the corrected value.
`projectId`	string	—	ID of your OneUptime Project in which this object belongs.
`rootCause`	string	—	What is the root cause of this status change?
`alertStateId`	string	Yes	Alert State ID Relation. Which alert state does this alert change to?

Parameters from the server's own tool schema.

Why create_alert_state_timeline is rated Medium

RECOMMENDED RULE

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

create_alert_state_timeline Rate-limited

create_alert_state_timeline 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.
