## Why update_tags_tool is rated Medium

Updating tags on notes is a write operation that modifies metadata without permanently deleting data. The change is reversible—tags can be removed or changed again. While the description is empty, the tool name and context from sibling tools (add_tags_tool, batch_update_properties_tool) and server capabilities indicate this performs metadata modification.

From the tool's own definition: "Tool name is 'update_tags_tool' and sibling tool 'add_tags_tool' confirms tag manipulation capability. Server description states it manages 'tags and links' and enables 'creating, and managing notes.' Tag updates modify note metadata reversibly."

## Use case

AI agents use update_tags_tool to create or update resources in Obsidian MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Obsidian MCP Server environment.
