Get performance metrics for multiple campaigns
AI agents call get_campaigns_performance to retrieve information from Brevo 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 retrieves performance metrics without modifying, executing, or deleting any data. It has no side effects and poses minimal security risk when misused by an AI agent—at worst, it exposes performance data the user is already authorized to access.
From the tool's definition Tool name 'get_campaigns_performance' and description 'Get performance metrics for multiple campaigns' indicate data retrieval only. The verb 'Get' and the absence of any action words (create, modify, delete, execute) confirm read-only functionality.
