Obsidian Multivault FAQs

Question 1

Can I use Obsidian Multivault with Claude's mobile app or remote connectors?

Accepted Answer

Yes, it supports an OAuth-protected Streamable HTTP endpoint for Claude's mobile app and remote connectors. This allows users to access their vaults from various Claude platforms, with secure login via a self-hosted OAuth 2.1 layer.

Question 2

What is Obsidian Multivault?

Accepted Answer

Obsidian Multivault is an MCP (Model Connector Protocol) server that provides Claude AI with secure read/write access to multiple Obsidian vaults hosted on a Virtual Private Server (VPS). It's designed for multi-user environments, allowing many individuals to share a single deployment while maintaining private vault access.

Question 3

What are the deployment requirements for Obsidian Multivault?

Accepted Answer

Deployment requires Node 20+ on a VPS. It's designed for ease of installation with a single-file deployment bundle. Configuration options allow for both stdio over SSH (for Claude Desktop) and an HTTP server mode (for remote connectors), often fronted by Caddy for public HTTPS access.

Question 4

How does it support multiple users and private vaults?

Accepted Answer

From a single deployment, Obsidian Multivault routes each user to their specific private vault. In HTTP mode, a distinct login passphrase determines the vault. For stdio over SSH, Claude Desktop launches with the user's designated vault path, ensuring personalized and secure access.

Question 5

What security measures are in place for data access?

Accepted Answer

The tool implements strict path safety, rejecting malicious paths and limiting write operations to an allowed file extension list (e.g., .md, .canvas). It also features self-hosted OAuth 2.1 for secure passphrase login, PKCE, and JWT access tokens, eliminating the need for third-party auth services.
