List campaigns in the current ad account (pagination + sort).
AI agents call list_campaigns to retrieve information from OpenAI Ads MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of campaigns with pagination and sorting capabilities. It performs data retrieval only, with no ability to create, modify, delete, or execute operations. Even though it touches an advertising/financial context (ad accounts), the tool itself only reads data and does not move money or commit financial obligations.
From the tool's definition Tool name is 'list_campaigns' and description states 'List campaigns in the current ad account (pagination + sort)' — a retrieval operation with no modification or side effects.
