Overview

Your AI can now sign up and pay with its own inbox and a user-controlled Agent Wallet.

Your AI can now sign up and pay.

Mermail gives your agent a private email and a user-controlled Agent Wallet, so it can sign up for services, receive verification codes, pay online, and keep every receipt. One MCP connection gives your agent the tools to complete the workflow from inbox to payment.

Info

You stay in control. Email effects require explicit authorization. For payments, PayBox enforces the delegated wallets, standing grants, approval, and signing policy you configured; Mermail does not add a second approval.

Give your agent a way to act

See how the Email module, mailboxes, agent, triage, and Agent Wallet fit together. Send and receive on a hosted address or a verified custom domain. Give your agent a dedicated address for registrations, verification codes, receipts, and ongoing conversations. Let your agent view delegated balances, transfer or swap assets, and pay one selected x402 resource without exposing private keys or raw signing access. Connect ChatGPT, Claude, Cursor, Codex, or another compatible assistant to Mermail's email and wallet tools. Build mailbox workflows with the API, CLI, Agent Skills, and task triage.

How Mermail fits into a workflow

Create a hosted Mermail address or use a verified custom domain. The Email module receives mail, and your agent can search conversations and prepare replies. Connect Mermail through MCP, install a focused Agent Skill, or use the CLI for a repeatable workflow. Connect PayBox to Agent Wallet when your agent needs Funding, transfers, swaps, or x402. Each action stays inside the exact terms you requested and the delegation and signing policy you configured in PayBox.
