Librarian FAQs

Question 1

Is Librarian secure and does it keep my data private?

Accepted Answer

Absolutely. Librarian runs entirely locally on your machine. Your vault data never leaves your computer, as it directly reads and writes files on disk and communicates with Claude over standard I/O. There are no network calls, telemetry, or cloud storage involved, ensuring complete privacy.

Question 2

Can I use Librarian with any markdown files, or only Obsidian vaults?

Accepted Answer

Librarian is designed to work seamlessly with both Obsidian vaults and any folder containing plain markdown files. While fully compatible with Obsidian's linking and YAML frontmatter, Obsidian does not need to be running for Librarian to function, offering flexibility and broader utility.

Question 3

What is Librarian and how does it empower Claude AI?

Accepted Answer

Librarian is an MCP server that integrates with Claude AI, giving it advanced capabilities to manage and interact with your Obsidian vault or any plain markdown files. It equips Claude with tools for deep search, knowledge graph analysis, automatic linking, and more, acting as a powerful AI-driven librarian for your digital notes.

Question 4

What advanced knowledge management features does Librarian offer?

Accepted Answer

Librarian provides a rich set of features including bidirectional knowledge graph traversal (BFS, shortest path), automatic wikilink detection with alias support, high-performance trigram-indexed full-text search, community detection via Louvain modularity, and interactive D3.js graph visualizations for comprehensive vault analysis.

Question 5

How does Librarian help organize and connect my notes?

Accepted Answer

Librarian automatically detects and generates `[[wikilinks]]` when Claude writes files, supports aliases, and helps connect ideas. It offers tools for knowledge graph traversal to explore topic neighborhoods, finds the shortest paths between notes, and uses community detection to identify topic clusters, greatly enhancing vault organization and discoverability.
