List all tags in Ghost
AI agents call list_tags to retrieve information from Ghost 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 returns existing tag data without creating, modifying, deleting, or executing any operations. It is a straightforward read operation that poses minimal security risk if misused by an AI agent, as it only exposes metadata about tags already in the system.
From the tool's definition Tool name 'list_tags' and description 'List all tags in Ghost' indicate a retrieval operation with no side effects.
