Implementation Reference

• src/obsidian_mcp/vault.py:744-870 (handler)

  Core implementation of list_templates in the ObsidianVault class that lists notes recursively in the specified folder (default Templates), returning NoteMetadata list or empty on folder not found. The handler in server.py calls this method.
