List all publications accessible with the API key
AI agents call list_publications to retrieve information from Beehiiv Analytics 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 and lists publication data without modifying, deleting, or executing any operations. It is a simple query operation that returns existing data. The read-only nature of the Beehiiv Analytics MCP Server, combined with the tool's list/retrieval function, confirms the Read category. Severity is low because exposing a list of publications poses minimal risk even if misused by an AI agent.
