Suggest tags matching a partial query.
AI agents call wiki_tags_search 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 performs a read-only query to suggest tags based on partial input. It retrieves matching tag data without creating, modifying, deleting, or executing code. The operation has no side effects on the Wiki.js instance. Given it operates on non-sensitive metadata (tags) and produces informational results, severity is low.
