Volta Notes
Burn-after-read encrypted notes for AI agents. Share secrets with users without them appearing in chat history — create a one-time URL, send it, they read it once and it's gone. AES-256-GCM E2E encrypted, decryption key never sent to any server.
Overview
Volta Notes MCP Server
Give your AI agent a secure credential pipeline. Instead of pasting passwords or API keys into chat, create a burn-after-read note and send the link — the agent reads it once and it's permanently destroyed.
How it works
- User creates a Volta note with a secret (or the agent creates one to send back)
- A one-time URL is generated — the decryption key lives in the #fragment, never sent to any server
- The recipient opens the link once — after that, the note is gone forever
Tools
create_volta_note
Encrypts content and stores it on the Volta canister. Returns a one-time URL. Use this when the agent needs to hand a secret back to the user.
read_volta_note
Accepts a Volta URL, retrieves and permanently destroys the note, decrypts locally, returns the plaintext. Use this when a user sends the agent a voltanotes.com link.
Installation
Add to your Claude Desktop or Claude Code config:
{
"mcpServers": {
"volta-notes": {
"command": "npx",
"args": ["-y", "@voltanotes/mcp"]
}
}
}
Security model
AES-256-GCM encryption runs locally on your machine
Decryption key is in the URL fragment — never transmitted to the Volta canister or any server
The canister only ever stores and returns encrypted ciphertext
Once read, the note is permanently deleted — no copy exists anywhere
Server Config
