Work with Obsidian vaults (plain Markdown notes) and automate via obsidian-cli.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Obsidian
Obsidian vault = a normal folder on disk.
Vault structure (typical)
- Notes: `*.md` (plain text Markdown; edit with any editor)
- Config: `.obsidian/` (workspace + plugin settings; usually don’t touch from scripts)
- Canvases: `*.canvas` (JSON)
- Attachments: whatever folder you chose in Obsidian settings (images/PDFs/etc.)
## Find the active vault(s)
Obsidian desktop tracks vaults here (source of truth):
- `~/Library/Application Support/obsidian/obsidian.json`
`obsidian-cli` resolves vaults from that file; vault name is typically the **folder name** (path suffix).
Fast “what vault is active / where are the notes?”
- If you’ve already set a default: `obsidian-cli print-default --path-only`
- Otherwise, read `~/Library/Application Support/obsidian/obsidian.json` and use the vault entry with `"open": true`.
Notes
- Multiple vaults common (iCloud vs `~/Documents`, work/personal, etc.). Don’t guess; read config.
- Avoid writing hardcoded vault paths into scripts; prefer reading the config or using `print-default`.
## obsidian-cli quick start
Pick a default vault (once):
- `obsidian-cli set-default "<vault-folder-name>"`

The line at the top of this page pins the label git:20260422.d32735f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
