Written setup, step by stepShow

Before you start

  • An account with permission to use the Gmail resources you intend to connect.

1. Connect Gmail to ApexGenius

  1. Open Gmail in Connections. Choose Connect, or Add connection when offered. Give the connection a name if prompted. If Gateway setup pending appears, contact ApexGenius support before continuing.
  2. Choose the account and review access. Sign in to the Google account that has access to the intended resources. Review the permissions Google requests, then return to ApexGenius.
  3. Review the connected account and resources. Find Allowed resources on the connection page or its Tools tab. Choose Refresh and enable only the connected mailbox. Resource selection does not add permissions to the Google account.
  4. Check the connection. Use Test connection or Check again and read the reported status. Add an AI agent from the AI agents page, choose Read only for the first test, and try the question below.

You choose what Hermes Agent can use

When you approve Hermes Agent, pick Full access, Read only, or Custom. Read only allows the Read operations and nothing else. Custom picks apps and tools one by one.

Limits in Gmail

  • · Before any mail is read, ApexGenius checks that the mailbox matches the account you connected.
  • · Google’s Gmail MCP has no send tool. Your AI can write drafts; you send them in Gmail.
  • · Enabled writes run immediately. Turn a tool off to block calls.
  • · Disconnecting stops future access. It does not undo a label, trash or spam change.

Questions people ask first

How do I connect Gmail?

Open Gmail in ApexGenius Connections, choose Connect, and sign in with the Google account for the mailbox you want. Connect each mailbox you use, and name the one your AI should read.

Can my AI send email?

No. Google’s Gmail MCP can write drafts but has no send tool. You review the draft and send it from Gmail.

Can my AI delete email?

It can move mail to trash or spam, and bring it back. Those tools are marked destructive. Enabled writes run immediately. Turn a tool off to block calls.

Can I start with read-only access?

Yes. Choose Read only when you add your AI agent. It can check the mailbox, search threads and read messages, and nothing else.

Will this list of tools change?

Google publishes the Gmail MCP tools, and ApexGenius reads Google’s live list on every search. This page shows the list as of its review date.
