WHAT IT DOES

What update_alert_severity does on OneUptime

AI agents use update_alert_severity 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
`id`	string	Yes	The unique identifier (UUID) of the Alert Severity to update. Required. Use list_alert_severities to find IDs.
`name`	string	—	Any friendly name of this object.
`color`	object	—	Color of this resource in Hex (#32a852 for example).
`order`	integer	—	Where this severity ranks among the project's alert severities: 1 is the most severe. A new severity without a number goes to the end of the list. Setting a num
`isArchived`	boolean	—	Archived severities stay on the alerts and episodes that have them, but can't be picked again. A project keeps at least one severity that is not archived.
`description`	string	—	Friendly description that will help you remember.

Parameters from the server's own tool schema.

Why update_alert_severity is rated Medium

An AI agent can call update_alert_severity faster than any human can review: one bad instruction and it creates or modifies resources in OneUptime by the hundred, each call as confident as the last.

RECOMMENDED RULE

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

update_alert_severity Rate-limited

update_alert_severity 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 OneUptime, apply this rule, and every update_alert_severity call is checked against it from then on.
