AI agents call get_ad_accounts to retrieve information from Meta Ads MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves ad account data without modifying, deleting, or executing external operations. It is a Read operation.
