List all tags.
AI agents call ghost_list_tags to retrieve information from Ghost CMS MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves tag data from Ghost CMS without creating, modifying, or deleting any resources. It has no destructive capability and produces no side effects beyond returning information. The low severity reflects minimal risk if misused by an AI agent—listing tags cannot harm data or operations.
