Vault Knowledge Overview

The vault-knowledge MCP server exposes read-only tools for searching concepts, finding contradictions, and retrieving articles from an Obsidian vault. It runs locally over stdio and can use a bundled synthetic espresso vault with zero configuration or a user-provided vault index and root. Concept search uses a locally downloaded embedding model on first run, while access is restricted to configured knowledge directories. Reach for it when an agent needs to inspect structured personal notes without changing them or sending vault data to a cloud service.
