rename_note · Obsidian Tools MCP Server MCP: Risk & Policy

WHAT IT DOES

What rename_note does on Obsidian Tools MCP Server

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

WHY IT NEEDS A POLICY

Why rename_note needs a policy

Renaming and moving notes are Write operations—they create or modify data reversibly. The changes can be undone by renaming/moving again. While this is not Read (it modifies state) or Destructive (the note content and structure remain intact, just relocated), it does alter vault structure.

From the tool's definition Tool description: 'Rename or move a note to a new location'. The operation modifies the metadata/structure of an existing note (its name and path) without deleting it, making it reversible.
