One agent
Stop a single agent from its own page or from the fleet page.
Kill switch
Stop any agent, straight away
One switch stops an agent's model calls, its tool calls and its approvals. It needs a reason, it has its own permission, and it stays on until a person lifts it.
Scope
Stop as much as you need
A group
Stop every agent that shares a tag, a kind or a blueprint, or a list you pick.
Every agent
One switch stops them all.
One tool or one server
Pause a single tool or a whole connected server, and the agents carry on without it.
Effect
What the switch does
Checked at every step
The switch is checked before each model call, each step of a run, each new token and each approval, and on calls that arrive over MCP and A2A.
Running calls are cut off
A model call or a tool call already in flight is dropped within seconds, and the run ends there.
A reason, on the record
Turning a switch on needs a reason, and the audit log records who did it and when.
Its own permission
Stopping agents is a separate permission, so the on-call team can hold it without being able to edit an agent.
No expiry
A stopped agent stays stopped until a person lifts the switch. It does not come back by itself.
Automatic triggers
Set a detector on a signal, such as the share of calls the guardrails refuse, the error rate or a changed tool definition. It can report only, warn, or stop the agent.
Questions
Frequently asked questions
How fast does it take effect?
New calls are refused at once, because the switch is checked before each one. A model call already in flight is dropped within seconds, and the run ends there.
Who can use it?
Anyone you give the permission to. It is separate from the permission to build or edit agents.
Does it work for agents we run outside Liyagent?
Yes, for what passes through Liyagent. An agent that sends its model calls through the Liyagent gateway is refused there while its switch is on.
Can an agent switch itself back on?
No. Only a person with the permission can lift a switch, and a stopped agent is refused a new token.
