What is Volta Notes?
Volta Notes gives your AI agent a secure credential pipeline. Instead of pasting passwords or API keys into chat, you create a burn-after-read note and send the link — the agent reads it once and it's permanently destroyed.
How to use Volta Notes?
Add the @voltanotes/mcp package to your Claude Desktop or Claude Code configuration using the provided npx command. The server exposes two tools: create_volta_note to hand a secret back to the user, and read_volta_note to accept a Volta URL, retrieve and destroy the note, and return the plaintext.
Key features of Volta Notes
- AES-256-GCM encryption runs locally on your machine.
- Decryption key lives in the URL fragment — never transmitted to any server.
- The Volta canister stores only encrypted ciphertext, never plaintext.
- Notes are permanently deleted after being read exactly once.
Use cases of Volta Notes
- An agent creates a one-time URL to securely hand a secret back to the user.
- A user sends a Volta link containing credentials, and the agent reads it without the secret persisting.
