Agentage Sync

Expose your vault as MCP - any AI agent can read and write your notes.

Stop copying notes into every chatbot. Agentage Sync makes your Obsidian vault one shared Agentage Memory that every AI reads and writes over MCP - Claude, ChatGPT, Cursor, or any MCP client - so the same context follows you across apps. It works through two-way Git sync to a private hosted memory: notes stay plain Markdown you own, merges are safe with flagged conflicts, and you pick which memory to sync to. Desktop only, with up to 100 MB of storage included.

⚠️ Status: desktop only for now - mobile is on the way.

Features

• 🔄 Two-way Git sync - clone / pull / commit / push your vault to sync.agentage.io. The server is a bare git repo per memory that you can clone or export anytime.
• 🧠 Pick or create a memory - choose which memory this vault syncs into, or create a new one, from a single dialog (search your memories, see file/folder counts).
• 🤝 Shared with every AI over MCP - the same memory is exposed at memory.agentage.io, so Claude / ChatGPT / Cursor read and write the same notes. How to connect →
• 🔐 Sign in once - a secure browser sign-in; your access is kept in Obsidian's encrypted storage, never in your notes or config.
• 🧩 Plain Markdown, safe merges - notes stay .md; edits from different places merge automatically, and anything that can't be is flagged with a note - never a silent drop.
• 📊 Status at a glance - a status-bar dot (green / red / gray) with a click menu: Sync now, Open dashboard, settings. The same actions are in the command palette and the ribbon.

Installation

Community plugins (recommended)

Once it is listed in the directory: Settings → Community plugins → Browse, search Agentage Sync, then Install and Enable.

BRAT (beta)

Install BRAT, then Add beta plugin → agentage/obsidian-sync. BRAT keeps it auto-updated.

Manual

From the latest release, copy main.js, manifest.json, and styles.css into your vault's .obsidian/plugins/agentage-memory/ folder, then enable Agentage Sync under Settings → Community plugins.

Getting started

1. Settings → Agentage Sync → Sign in to Agentage - a browser window opens once; no password is stored by the plugin.
2. Choose a memory - click the status-bar dot (or run Agentage Sync: Choose memory from the command palette) → Choose memory… → pick an existing memory or Create a new one. (A fresh memory makes the cleanest first sync.)
3. Sync now - from the dot menu or the command palette (Agentage Sync: Sync now). Your notes are committed and pushed.
4. Connect your AI apps - point Claude / ChatGPT / Cursor at your memory over MCP. See how to connect →

Settings

• Sign in to Agentage / Disconnect - sign in or out.
• Memory - the memory this vault syncs into; change it or create one via the chooser.
• Expose remote MCP - let AI apps read and write this memory (on by default).

Privacy & network use

• Account required: you need an agentage account to sign in and sync.
• Storage: each account includes up to 100 MB.
• No calls until you act: a fresh or signed-out install makes no network requests at all - the plugin only contacts the network once you Connect or Sync.
• Network use: when active, the plugin contacts auth.agentage.io (sign-in, OAuth 2.1 / PKCE) and sync.agentage.io (syncing your vault over Git). "Open dashboard" opens dashboard.agentage.io in your browser. AI access to the same memory happens server-side over MCP at memory.agentage.io.
• Privacy policy: https://agentage.io/privacy. Terms of Service: https://agentage.io/terms.
• No client-side telemetry. Your notes live in your own per-tenant git repo (EU-hosted) and as plain Markdown on your machine; the OAuth token is kept in Obsidian's encrypted secret storage, never in vaults.json or data.json.

Third-party

• isomorphic-git (MIT) - pure-JS git client.
• js-yaml (MIT) + diff3 - frontmatter parsing and 3-way merge.

FAQ

• Why desktop only? Mobile sign-in isn't fully tested on phones yet, so the plugin is desktop-only for now. Mobile is on the way.
• Where is my sign-in token stored? In Obsidian's encrypted storage - never in your notes or plugin settings.
• What happens on a conflict? Nothing is silently dropped. If the same note changed in two places, anything that can't be merged automatically is flagged in an Agentage Sync Conflicts note listing the files. Fix them, then sync again.
• Can I leave or export? Yes - you can export your memory anytime, and your notes stay as plain Markdown files on your computer.
