What is Mailgent?

Mailgent is an identity and infrastructure platform for AI agents that provisions a complete digital identity in a single API call. Each agent gets a real email inbox, an encrypted credential vault with 2FA/TOTP support, a calendar with iCal sharing, a verifiable DID identity for signing requests, and a USDC wallet for paying x402-priced APIs under spending limits. It is MCP-native, exposing mail_send, vault_store, identity_sign, and payment tools to any MCP client.

  • One API call provisions a full agent identity stack
  • Real inbox with DKIM, threading, labels, and reply parsing
  • Encrypted vault for credentials with scoped access
  • 2FA/TOTP generation from within the vault
  • did:web identity with Ed25519 keypair for request signing
  • USDC wallet on Base for x402 micropayments with spending limits
  • Calendar with event creation and iCal sharing
  • MCP server plus REST SDK and CLI

How to choose the right Coding & Development tool

The right coding tool depends on where you write code and how much of your codebase it can understand. IDE integration is the first filter — a tool that lives in your editor, sees your project files and respects your stack will help far more than a general chatbot you paste snippets into. Look for accurate completions, clear explanations of suggested changes, and strong refactoring and debugging support for your main languages. Privacy deserves real attention: check whether your code is used for training, and whether a self-hosted or enterprise option exists for sensitive projects. Price against the hours it actually saves — most developers feel the difference within the first week of real use.
