AI agents that can email, pay APIs, sign, and store secrets
Agents keep hitting the same walls: no inbox, no safe credential store, no way past a 2FA gate, no way to pay for a downstream API, no verifiable identity. Mailgent fixes this in one curl call. Every agent gets a real inbox (DKIM, threading), encrypted vault, TOTP/2FA, USDC wallet for x402-priced API payments, verifiable DID (Ed25519), and a calendar. MCP-native. Works with Claude, Cursor, OpenAI, LangChain, CrewAI, Hermes Agent, OpenClaw, NemoClaw, n8n, and more. Everything live in seconds.
