Find all notes that link to a specific note
AI agents call get_backlinks to retrieve information from Multi-Tool MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about note relationships within an Obsidian vault. It performs a read-only search operation with no side effects—it does not create, modify, delete, or execute anything. The operation is purely informational and cannot cause harm through misuse beyond potential information disclosure of vault structure.
