Open-source MCP server over a git-backed Obsidian vault. Single-user, self-host. Six tools, hybrid search, provenance/blame, auto-link discovery.
Обзор
Six tools, one git-backed vault, single-user. Claude, ChatGPT, Cursor, or any MCP-compatible client connects and gets structured access — search, read, write-back, graph diagnostics. Your vault stays yours: markdown files in a git repo, versioned forever. Grove was a hosted product 2026-04 → 2026-05. The repo you're looking at is the open-source cathedral that came out of it: a personal MCP layer over an Obsidian vault, single-user, self-host. The multi-tenant SaaS layer, autonomous-agent layer, encryption, trails, waitlist, and admin portal have all been stripped. See RETROSPECTIVE.md for the full history. Every write is a git commit. Every commit can carry provenance trailers that the read path surfaces via blame so future readers know what's the user's standing thinking vs an AI's moment-in-time synthesis.

Grove
Open-source MCP server that makes your Obsidian vault searchable and writable from any AI client.
Six tools, one git-backed vault, single-user. Claude, ChatGPT, Cursor, or any MCP-compatible client connects and gets structured access — search, read, write-back, graph diagnostics. Your vault stays yours: markdown files in a git repo, versioned forever.

About this repo. Grove was a hosted product 2026-04 → 2026-05. The repo you’re looking at is the open-source cathedral that came out of it: a personal MCP layer over an Obsidian vault, single-user, self-host. The multi-tenant SaaS layer, autonomous-agent layer, encryption, trails, waitlist, and admin portal have all been stripped. See
RETROSPECTIVE.mdfor the full history.
The six tools
| Tool | What it does |
|---|---|
query |
Hybrid BM25 + vector + title search with RRF fusion. Returns ranked snippets with URLs. |
get |
Read a note by path or title. Surfaces per-segment provenance (durable vs perishable voice). |
multi_get |
Batch read via glob or comma-separated paths. |
write_note |
Create / update / soft-delete / hard-delete / move a note. Single op or batch (atomic optional). |
list_notes |
List notes matching a pattern. Optional alias resolution. |
vault_status |
Health, history, diagnostics, graph, lifecycle digest, discovery state, perf counters. |
Every write is a git commit. Every commit can carry provenance trailers that the read path surfaces via blame so future readers know what’s the user’s standing thinking vs an AI’s moment-in-time synthesis.
Quick start
You need:
- Node ≥ 22
- A git-backed Obsidian-style markdown vault on disk
- A QMD index for the vault (Grove reads BM25 + vector hits from it)
- A Voyage AI API key for per-write embeddings (
voyage-4-large)
git clone https://github.com/jmilinovich/grove.git
cd grove
npm install
Set the env vars:
export GROVE_VAULT=/path/to/your/vault # absolute path to the git repo
export GROVE_API_KEY=$(openssl rand -hex 32) # your bearer token — keep secret
export VOYAGE_API_KEY=... # Voyage AI key for embeddings
