Frequently Asked Questions about Mailgent

Can Mailgent agents send and receive real emails from actual email addresses?

Yes, Mailgent provides a real email inbox where agents can send, receive, and organize messages with full threading support. Each agent identity gets its own functional email address provisioned in a single API call, with no separate mailbox setup required.

How does Mailgent handle credential storage and access control for agents?

Mailgent stores credentials in an encrypted vault with scope-gating by default, meaning agents only access the credentials they need for specific tasks. This least-privilege approach prevents an agent from reading every stored credential even if it compromises one service's access.

Can Mailgent agents make USDC payments through the API?

Yes, each agent gets a USDC wallet on Base that can process payments directly. This lets agents fund their own API calls or pay for services autonomously, without requiring a human to approve each transaction.

What platforms and interfaces does Mailgent support for integration?

Mailgent is MCP-native and works with Claude, Cursor, and ChatGPT through the Model Context Protocol. It also offers REST APIs and SDKs for direct integration, giving developers flexibility in how they connect agent workflows.
