Hermes Agent

Hermes Agent by Nous Research has a first-class OpenViking memory provider built in. No plugin to install — just point Hermes at your OpenViking server and it handles memory storage, recall, and extraction natively.

Keep the Python environments separate

Hermes connects to OpenViking over HTTP, so OpenViking does not need to be installed in the Hermes Python environment. Run the OpenViking server in its own virtual environment or container. Do not use --force-reinstall to add or upgrade OpenViking in an existing Hermes environment: a Hermes release may pin dependency versions that differ from OpenViking's supported, security-patched versions. If you intentionally combine both applications in one environment, resolve them together and run python -m pip check before starting either service.

Setup

• Custom: URL (default http://127.0.0.1:1933) and API key; leave the key empty for local dev
• Reuse an existing ovcli.conf profile if the wizard offers one
