Common questions
Is Netherstone safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.6.0-beta.2) reached the registry 7 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code.

README from the maker
Open the README
Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.
Netherstone is a free, open-source desktop app for documents and drawings. Each document, called a shard, is a Markdown file in a folder you pick.
Download
Get the latest version for Windows, macOS or Linux from Releases.
On Windows, the installer shows "Windows protected your PC". Click More info, then Run anyway. Windows shows this because the installer isn't code-signed yet. We plan to sign it in a future version.
Features
- An editor that formats Markdown as you type
- Search,
@links and#tags - Drawings, images, PDFs, audio and video
- A Gallery of every attachment in your vault
- Charts from tables, and an Overview of your vault
- Every version of a shard or drawing in History
- Import from Word, PDF, HTML, Markdown and CSV, and export to PDF, Word or HTML
- Open folders and files from the terminal (
netherstone .) or your file manager - Free sync through your own GitHub account
- Light, Dark and three more themes
AI apps
Netherstone has a built-in MCP server, so your AI apps can search your vault, read and write shards, fix links, edit drawings and tables, and go back through History. It's off until you turn it on:
- Open Settings > AI apps and turn on Connect your AI apps.
- Pick the vaults AI apps may use.
- Click Connect next to your app, then restart it. For any other app, click Copy setup and paste it into that app's MCP settings.
AI apps can't delete anything, and every change they make is saved in History first, so you can undo it.
Building from source
You need Node.js 24.22.2+, pnpm 12, Rust and the Tauri prerequisites for your OS.
pnpm installpnpm tauri dev # run the app pnpm test # run the tests pnpm tauri build # build an installer
The editor also has browser tests. Build the frontend once, then run them in a real Chromium (the first run downloads it):
pnpm exec vite buildpnpm exec playwright install chromium pnpm test:e2e
