obsidian mcp

Connect your favorite agent to your Obsidian vault.

A hosted MCP server for the vault you sync with Obsidian Sync. Ask Claude or ChatGPT to file a note, update a project or find what you wrote last spring, and the change turns up on every device you own.

Sign in with Google

Nothing to install, run or host. Sign in, connect your vault and paste one URL into your AI client. Your own server runs in the cloud for you and wakes when you ask.

Needs Obsidian Sync, Obsidian’s paid sync service. Invite-only beta.

Ask in the chat. It’s in the note.

Your AI client, and the same note in Obsidian a few seconds later.

Standup’s done. Log today’s decisions in Project Atlas and tick off the export fix.

Done. Two decisions are under Decisions, dated today, and the export fix is ticked off. Dana’s API key is the only open blocker.

Pricing

One plan while the beta runs.

The careful parts.

What we hold, where it lives, and how to make it disappear.

Your encryption password stays in the browser.
If your vault has an end-to-end encryption password, the browser turns it into your vault key and sends only the key.
Credentials live in one sealed secret.
Your Obsidian access token and vault key go into a single encrypted secret that only your server can read. Never our database, never our logs.
The server is yours alone.
Every account gets its own. Only the relay can reach it, and only after you sign in with Google.
Deleting takes everything we hold.
Deleting your server removes it, its snapshots and the stored credentials. Your notes stay in Obsidian Sync, and the Obsidian access token stays valid until you revoke it in your Obsidian account.
