Feature & Specification Comparison

Specification	Volta MCP Server iamredmh Security	S Gw sgateway Security
Summary	Burn-after-read encrypted notes for AI agents. Create and read self-destructing notes via Volta Notes with AES-256-GCM E2E encryption — the decryption key never leaves the URL fragment. Secure credential handoff between users and agents without secrets appearing in chat history.	Local credential approval and execution gateway for AI coding agents. Agents receive typed handles instead of raw API tokens, SSH keys, and cloud credentials; one-time approvals bind the credential, command, arguments, working directory, environment bindings, and target. Injects credentials only into the approved child process, sanitizes output, and records a local audit trail. Install with npm install -g @s-gw/s-gw.
