aarvion-guard-hermes
Governance plugin for Hermes agents. Intercepts tool calls and inbound messages, forwarding them to the local Aarvion Guard daemon for policy evaluation.
Install
pip install aarvion-guard-hermes
hermes plugins enable aarvion-guard
Setup
-
Install the guard daemon:
npx @aarvionai/guard -
Pair with your Aarvion dashboard:
aarvion-guard init <pairing-code>
-
Start the guard and run your agent:
aarvion-guard service start hermes run
Container
For non-bypassable enforcement, run the pre-built governed container:
docker run -e AARVION_TOKEN=<token> aarvion/hermes-governed:latest
How it works
The plugin registers two Hermes hooks:
- pre_tool_call - every tool invocation is sent to the guard PDP for allow/deny/ask evaluation
- pre_gateway_dispatch - inbound messages are checked against channel governance policies
The guard daemon handles surface classification, DLP scanning, and policy evaluation. The plugin is intentionally thin - it sends raw tool name + args and trusts the guard's Go normalizer.
