What is the Stellavault MCP Server?

Local-first MCP server: Claude searches, asks & drafts from your Obsidian vault. 21 tools, no keys.

What you get

Karpathy's self-compiling wiki × Zettelkasten — fully local, vault-safe, and MCP-native.

  • 🧠 It compiles itself. Drop in a PDF, a YouTube link, or a half-formed thought — Stellavault extracts it to raw/, then compiles a clean _wiki/ with concepts and backlinks. Knowledge that organizes itself as it grows
  • 🌌 Your mind, in 3D. A real-time neural graph (React Three Fiber) — cluster coloring, constellations, heatmaps, a timeline, and a multiverse P2P view. A way to see the shape of what you know
  • 🤖 Claude reads your entire vault. A first-class MCP server (21 tools): Claude can search, ask, draft, lint, and analyze your knowledge from Claude Code, Claude Desktop, Cursor, Windsurf, or VS Code
  • ⏳ It never silently forgets. FSRS memory decay surfaces the real notes you're about to lose — plus gap, contradiction, and duplicate detection across the whole vault
  • 🔒 Local-first. Vault-safe. Zero keys. Local embeddings, an on-device vector store, and your original files are never modified. Nothing leaves your machine unless you opt in
