List all publications accessible with this API key.
AI agents call list_publications to retrieve information from Beehiiv MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that queries and returns a list of publications. It has no side effects, does not modify data, and does not execute external operations. The blast radius of misuse is minimal—an agent could only enumerate accessible publications, which is informational. This is a standard Read category tool.
From the tool's definition Tool name 'list_publications' and description 'List all publications accessible with this API key' indicate a pure query operation that retrieves and displays data without modification.
