WHAT IT DOES

What activate_campaign does on NeuronSearchLab

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

WHY IT NEEDS A POLICY

Why activate_campaign needs a policy

This tool modifies existing campaign data by changing its operational status. The action is reversible (a campaign can be paused again), and it triggers side effects in a recommendation/personalization system (resuming rule injection), making it a Write operation rather than Read.

From the tool's definition Tool description states it 'Activate a paused campaign so it starts injecting rules again.' This modifies the state of a campaign from paused to active, which is a reversible state change.

Verdict

activate_campaign Rate-limited

activate_campaign 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.
