Hermes Agent SSH access enhanced with Termalin for improved security

This article details how the Hermes Agent can be configured to access remote servers via SSH, highlighting its current limitations and proposing an alternative solution using Termalin. The default SSH backend requires a private key on the agent machine, which poses security risks and limits access to a single host. It also details several known issues with the SSH backend across different operating systems. As a more secure and flexible alternative, the post introduces Termalin, an SSH client with a hosted MCP server that allows Hermes Agent to connect to multiple servers without needing a private key on the agent itself, using short-lived certificates and outbound-only connections.

    Give Hermes Agent SSH access to your servers without handing it a key

    <p>Hermes Agent already runs shell commands on a remote box. Its SSH terminal backend points at one host and runs each command over <code>ssh</code>. That is fine for a single server. The moment you have more than one, or you do not want a private key sitting on the machine that …
