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
Its own inbox
Give your agent a dedicated address for registrations, verification codes,
receipts, and ongoing conversations.
A user-controlled Agent Wallet
Let your agent view delegated balances, transfer or swap assets, and pay one
selected x402 resource without exposing private keys or raw signing access.
One MCP connection
Connect ChatGPT, Claude, Cursor, Codex, or another compatible assistant to
Mermail’s email and wallet tools.
APIs and automation
Build mailbox workflows with the API, CLI, Agent Skills, and task triage.
How Mermail fits into a workflow
1
Create an agent inbox
Create a hosted Mermail address or use a verified custom domain. Your agent
can receive email, search conversations, and prepare replies.
2
Connect your AI
Connect Mermail through MCP, install a focused Agent Skill, or use the CLI
for a repeatable workflow.
3
Add controlled payments
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.
