Which Gmail and Sheets actions does it have?

Just the operations you allowlist on each node, such as reading messages and appending rows. Sending or editing is only possible if you turn that operation on.

Do I need to self-host the agent?

No. NoClick runs the Hermes harness and connects Gmail and Google Sheets as tools, with nothing to install.

Will it send emails automatically?

Only if you expose Gmail's send operation. Without it, the agent prepares the email content and reports it rather than sending.

Hermes is an open agent based on Nous Research’s Hermes models. NoClick runs it for you and adds your connected apps as tools.

How do I give Hermes access to an app?

Connect the app's integration node to the agent's tools handle and pick the operations to expose. Each becomes a callable tool.

Do I need my own infrastructure?

No. The harness runs in a hosted sandbox and NoClick handles credentials for the apps you connect.

Can Hermes use multiple apps at once?

Yes. Wire in several integrations and the agent can use them together in a single run.

Connect Hermes to Gmail and Google Sheets

Give Hermes Gmail and Google Sheets together and it can read your inbox and keep a spreadsheet up to date from it without manual entry. It can pull details out of incoming email and append rows to a sheet, or read a list from Sheets and send a tailored email to each entry. The two tools turn the agent into a steady operator for lead capture, tracking, and follow-up.
