Seekstone
Give Claude your Obsidian vault — without the context tax
Seekstone is an open-source MCP server that connects Claude (or any MCP client) straight to your Obsidian vault by reading it from disk. No plugin, no app running, nothing leaves your machine. Search returns ~2 KB of ranked excerpts — not megabytes of full notes. Reproducible benchmarks included.
Hey Product Hunt 👋
I built Seekstone because connecting Claude to my Obsidian vault kept eating the context window. Most Obsidian MCP servers proxy a REST plugin and return full note content for every search match — in my benchmarks, one broad query on a 10k-note vault returned 95 MB, peaking at 370 MB (~98M tokens) in a single tool call. The AI's memory is gone before the conversation starts.
Seekstone reads the vault straight from disk and returns ranked excerpts instead of whole notes:
⚡ ~2 KB per search at 10k notes — flat as your vault grows (up to ~47,000× less than REST-proxy in the worst case)
🚀 6 ms warm search — ~70–250× faster than every other Obsidian MCP server I benchmarked
🔒 Local-only: no Obsidian app required, no network calls, no telemetry, sandboxed to your vault
🛠️ 17 tools: full-text search, structured frontmatter queries, backlinks, outlines, tags, daily notes, and 8 conservative write tools (frontmatter edited in place, verified byte-for-byte)
The part I'm proudest of: the benchmarks are reproducible. The harness, the synthetic 1k/5k/10k-note test vaults (built from the 1911 Encyclopædia Britannica), and every report are committed to the repo — clone it and re-run them yourself.
Setup is one command: npx -y seekstone init — works with Claude Desktop, Claude Code, Cursor, and VS Code, plus a one-click .mcpb bundle for Claude Desktop (no terminal needed).
MIT licensed. I'd love your feedback — especially if you run a big vault. AMA 👇
The local-only approach is honestly what sold me on this, super clean setup. One thing I'd love to see is fuzzy or typo-tolerant search, because right now if I slightly misspell a tag or a term in my vault the results just miss it entirely. Even a simple edit-distance fallback on titles would make this feel way more forgiving day to day.
honestly this is exactly what i needed for my vault, love that nothing leaves my machine. one thing that would make it even better is supporting some kind of incremental indexing so the initial setup on a large vault doesnt take forever, maybe with progress feedback so you know its not just hanging
