WHAT IT DOES

What update_label does on OneUptime

AI agents use update_label 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 Label to update. Required. Use list_labels to find IDs.
`name`	string	—	Any friendly name of this object.
`color`	object	—	Color of this resource in Hex (#32a852 for example).
`isArchived`	boolean	—	Archived labels stay on everything that has them, but can't be added to anything again.
`description`	string	—	Friendly description that will help you remember.

Parameters from the server's own tool schema.

RISK

Why update_label is rated Medium

An AI agent can call update_label 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.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

update_label Rate-limited

update_label 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_label call is checked against it from then on.
