Email & identity for AI agents

Give your AI agent an inbox.

A real email address, encrypted vault, calendar, and verifiable identity for every agent you run — plus a USDC wallet to pay for what it uses. One API call to provision.

One identity, six capabilities

Everything an agent needs to operate in the world.

It starts with email. Identity is the root of trust; mail, vault, 2FA, calendar, and a wallet are the capabilities that hang off it.

Mail

A real inbox at name@mailgent.dev. Your agent sends, receives, threads, and labels email over a clean API or MCP — verified senders, DKIM, the works.

Vault

Encrypted credential store. Stash API keys, tokens, and secrets your agent needs, retrieved per-scope and never logged.

2FA / TOTP

Time-based one-time codes your agent can generate to get past 2FA gates — with backup codes, all inside the vault.

Calendar

Create events, manage availability, and share an iCal feed so your agent can coordinate time like a person would.

Identity (DID)

A did:web identity with an Ed25519 keypair. Your agent signs requests and proves who it is — the root of trust everything hangs off.

USDC wallet

A funded wallet on Base. Your agent pays x402-priced URLs per call under spending mandates you set — no cards, no human in the loop.

How it works

From zero to a working agent identity in one call.

No mailbox setup, no key management, no OAuth dance. Provision and go.

01

Provision

One API call returns an Identity: an email address, a DID + signing key, an encrypted vault, a calendar, and a USDC wallet — all live in seconds.

02

Connect

Plug the agent's key into the MCP server, CLI, or SDK. It gets ready-made tools — mail_send, vault_store, calendar_create, identity_sign, and more.

03

Operate

Your agent reads its inbox, stores credentials, gets past 2FA, books time, signs requests, and pays for APIs — with a real, verifiable presence.

For developers

One call to provision. One key to use it all.

Sign an agent up and it gets an inbox, a DID, a vault, a calendar, and a wallet — reachable as ready-made MCP tools or REST.

  • MCP-native — works in Claude, Cursor, ChatGPT, and any MCP client.
  • CLI + SDK for shell agents, cron jobs, and your own code.
  • Every tool is scope-gated by the agent's key. Least privilege by default.
  • Hosted at api.mailgent.dev/mcp, or run it locally.
