Mcp Standardnotes
Gives Claude secure read/write access to your Standard Notes vault using protocol 004 encryption. All decryption happens locally with libsodium primitives (Argon2id + XChaCha20-Poly1305), and your master key never leaves your machine. Exposes tools for listing, searching, creating, updating, and deleting notes and tags, plus batch operations like notes_create_many for up to 50 notes at once. Session tokens live in your OS keychain, not plaintext files. Stdio only, so no network port ever opens. Supports both official Standard Notes cloud and self-hosted instances with optional TLS certificate pinning. Reach for this when you want Claude to organize, search, or draft notes while keeping end-to-end encryption intact.
