Single-user, self-hosted MCP server that gives Claude read/write access to your Obsidian vault — Docker + Cloudflare tunnel, OAuth 2.1, one-command start
View on GitHub ↗A single-user, self-hosted MCP server that gives Claude — claude.ai web, Claude mobile, Claude Desktop, Claude Code — read/write access to your own Obsidian vault. It runs entirely in Docker on your machine; a Cloudflare tunnel makes it reachable from those Claude surfaces without opening any ports yourself.
30 tools cover the vault the way Obsidian sees it: reading and writing notes, sections, frontmatter and attachments; the link/tag graph (backlinks, orphans, hubs); structured queries and recency; safe concurrent edits and multi-note transactions; canvases; templates; daily notes. See "What Claude can do" below.
Handing this to someone non-technical — a manager, a marketer, anyone who just wants their notes to work with Claude? Give them docs/user-guide.md: what it's for, how to connect, and copy-paste prompts.
v0.3.1 — beta. Built for the owner and technically comfortable colleagues who clone this repo; not (yet) a hosted product.
Verified end-to-end: Linux host · Claude Code · claude.ai web (all tools, via a live quick tunnel) · Docker smoke test in CI. Implemented but not yet verified by a real run: Claude mobile app · cloudflare (token) tunnel mode · Windows and macOS launchers · reconnect after a tunnel restart. Issues and pull requests are welcome — see CHANGELOG.md for what shipped and SECURITY.md for reporting vulnerabilities.
- Docker Desktop (Windows/macOS) or Docker Engine + Compose v2 (Linux) - Node.js 24.x - git
