Credentials. The plugin uses your logged-in Claude Code session, so anyone with access to this machine can act through that subscription.
Who it is forA Claude Pro or Max subscriber who wants Hermes to use that subscription instead of a separate API key and per-token bill.
The problemPaying a separate per-token API bill on top of an existing Claude subscription doubles the cost for people who already have a plan.
The outcomeHermes keeps its own loop, tools and approvals while the logged-in claude binary handles model turns.
What you need first
- Hermes Agent installed (the README gives a curl install script in the hermes-agent repo)
- The hermes CLI available in your terminal
- Accounts and credentials for the specific service you connect, such as Home Assistant, Spotify, Langfuse, Snyk or X
- Each plugin's own requirements, shown by hermes plugins info <name>
Steps
- Install Claude Code and log in with your Claude subscription, since the plugin drives the logged-in claude binary.
- Run
hermes plugins install claude-subscription-directsdk. - Run
hermes modeland pick Claude Subscription DirectSDK (Experimental). - Send Hermes a short test prompt.
- If you see an install hint, install Claude Code and try again.
Prompt for your agent
Using the repo NousResearch/hermes-official-plugins, install the claude-subscription-directsdk plugin, select it in `hermes model`, and send Hermes the prompt <test-prompt>. Expected output is a normal Hermes reply with no API key set; verify that the reply came from the plugin and not from another provider.
Caveat. The README marks this plugin as experimental, so expect changes and confirm it still works after each plugin update.
