Overview
Each Parlant agent runs on dedicated infrastructure and includes a skill for administering its virtual private server (VPS). You can ask Hermes to inspect the system, install or configure software, and adapt the server when a task needs more than the standard image.
This is full system access, not a simulated settings panel. Review proposed commands before approval, especially when they change networking, authentication, storage, or running services.
Make changes survive replacement
One-off system changes may be lost when the server is recreated or upgraded. Put repeatable setup scripts in $HERMES_HOME/vps-customizations/. During upgrade or recreation, the Parlant Agents dashboard lets you choose whether registered customization scripts should run on the replacement server.
A server becomes marked as customized after Hermes uses administrator access. The dashboard shows that state and requires confirmation before replacement. Old scripts can conflict with a newer managed image, so keep them small, readable, and safe to run again.
Safer workflow
- Ask Hermes for a plan and the exact commands.
- Create a manual backup before a significant change.
- Test one small change and verify the result.
- Save only repeatable setup as a customization script.
- Keep credentials outside scripts and versioned files.
