Get a listing of chapters visible to the user
AI agents call list_chapters to retrieve information from BookStack 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 existing chapters from a BookStack wiki instance. It performs a read-only query operation with no side effects, no data creation or deletion, and no external execution. The blast radius of misuse is minimal—an AI agent could only enumerate chapters it already has visibility to.
From the tool's definition Tool name 'list_chapters' combined with description 'Get a listing of chapters visible to the user' indicates a query/retrieval operation with no data modification.
