Get the site navigation tree (per locale).
AI agents call wiki_navigation_get to retrieve information from Mcp Wikijs Mv without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves navigational metadata from a Wiki.js instance. It queries and returns structural information (navigation tree) without creating, modifying, deleting, or executing anything. The blast radius of misuse is minimal—an agent could only gather information about the wiki's structure. No data is altered, no commands are executed, and no sensitive operations are triggered.
From the tool's definition Tool name 'wiki_navigation_get' and description 'Get the site navigation tree (per locale)' indicate a retrieval operation with no side effects. The verb 'Get' and absence of any modification, deletion, or execution keywords confirm read-only semantics.
