A skill for working with Obsidian vaults, which are folders containing linked notes, tags, and metadata. It routes note changes, app actions, and Git backups to the appropriate tool.

It helps search, edit, move, rename, tag, and update note metadata, open notes in Obsidian, and back up or sync a vault with Git.

It reduces the risk of using the wrong tool for a vault operation and helps prevent broken links or corrupted notes when renaming them.

About the project

MCPVault is a local Model Context Protocol server that lets compatible AI clients read, search, and edit notes stored in an Obsidian vault. It is for users who want coding agents and other supported clients to work with their vault while restricting file access to its configured root. The catalogue entries provide add-ons for using MCPVault with AI coding agents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00048	$0.02828
Opus 5	$0.00024	$0.01414
Sonnet 5	$0.00010	$0.00566
Haiku 4.5	$0.00005	$0.00283

Security

Grade A, and why

obsidian scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Obsidian Skill

Routing Policy

Use the backend that best matches user intent:

MCP (default for vault data operations)
- Read/write/patch/search notes
- Move/rename notes with move_note, then explicitly repair backlinks
- Frontmatter and tag updates
- Metadata and batch note operations
Obsidian CLI/App context (only when app context is needed)
- Open a note in Obsidian from URI
- Trigger app/plugin workflows that MCP cannot perform
CLI git (sync/backup workflows)
- Initialize repo, configure remote, commit, pull, push
- Periodic or manual vault backup/sync requests

When a request is ambiguous, pick MCP first unless the user explicitly asks for sync/backup/git/app behavior.

Safe Note Rename Workflow

Use MCP move_note for every note move or rename, even when Obsidian is running. Do not invoke the Obsidian CLI move command automatically: delayed link rewrites can apply stale byte offsets to notes edited after the move began, silently corrupting unrelated content (#176). Reconsider CLI moves only after an upstream fix has been independently retested.

Backlink preservation is an explicit, verifiable second step:

Before moving, search for the old wikilink target using both its vault-relative path and filename without the extension. If Obsidian is running, its read-only backlinks command may supplement discovery, but it does not replace the MCP search.
Move the note with MCP move_note.
Read each referring note and patch only exact wikilink targets, including embeds and links with aliases or fragments. Preserve display text (|alias) and #heading / #^block-id suffixes while changing the target.
Search again for the old path and basename. Report any remaining references instead of claiming success.
search_notes returns at most 20 results. If a search reaches that cap, or the old basename is ambiguous, tell the user exhaustive backlink repair cannot be proven and ask before continuing with a broader scan.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

obsidian is a skill published in the GitHub repository bitbonsai/mcpvault (1,645 stars, last pushed 5d ago), licensed MIT. It adds 48 tokens to every session and 2,828 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
