sandgate: a human gateway for AI agents

sandgate.dev Observed source

Editorial interest 78/100 Selection signal · not a rating of the site

A self-hosted MCP server that lets AI agents request human approvals, 2FA codes, and email-verification help without handing secrets directly to the model.

Landing page captured for the 2026-09-05 issue.

Field notes

The homepage models the workflow as a sequence of agent request, phone decision, and returned result rather than as unrestricted credential sharing. Its examples include a 30-second TOTP code, timeout-to-deny behavior for payment approval, and an input path for SMS codes. The page attributes stronger protections to the system, including end-to-end encryption for answers and vault storage for TOTP seeds.
