create_campaign · NeuronSearchLab MCP: Risk & Policy

WHAT IT DOES

What create_campaign does on NeuronSearchLab

AI agents use create_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 create_campaign needs a policy

This tool creates new campaign objects and modifies ranking behavior within the system. While reversible (campaigns can be ended or deleted), it has side effects on the recommendation engine's output and could affect user experience if misused. It does not retrieve data (Read), execute arbitrary code (Execute), permanently destroy data (Destructive), or involve financial transactions (Financial).

From the tool's definition Tool creates a time-bounded campaign that injects ranking rules between a start and end datetime. The word 'create' indicates data creation, and 'injects ranking rules' shows modification of the recommendation system's behavior.

create_campaign Rate-limited

create_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.
