What is a Vault MCP and how to use it?
▸ TL;DR
A Vault MCP gives Claude access to a personal knowledge base — Obsidian, Logseq, or custom note vaults. Read your notes, search the graph, capture new entries from chat.
Best MCPs by toolFull answer
A Vault MCP indexes your personal knowledge files (markdown notes, daily logs, project docs) and exposes search + write tools to Claude. The most common is the Obsidian vault MCP — it reads your .md files, resolves [[wiki links]], walks the graph. Capabilities: full-text search, graph traversal, daily note creation, tag queries. Use cases: ask Claude "summarize my notes about MCP from last month", or "create a daily note with today's standup". Unyly hosts Unyly Vault as a managed alternative — same workflow without setting up Obsidian.
