Get information about a custom audience
AI agents call get_audience_info to retrieve information from Meta Marketing API MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data about audiences without side effects. However, the medium severity reflects that audience information can be sensitive (potentially containing demographic, behavioral, or targeting data), and misuse could enable unauthorized audience inspection or data exfiltration. The read-only nature prevents irreversible damage but the data sensitivity warrants attention in security controls.
From the tool's definition Tool name 'get_audience_info' with description 'Get information about a custom audience' indicates retrieval of audience data with no modification or deletion.
