Penny
Penny core memory and private notes for Hermes.
Good to know before installing
Automatic recall sends the first 4,000 characters of each nontrivial local prompt to app.mypenny.ai as a search query, and the agent can save notes there through penny_remember without a Hermes approval prompt; works only in local CLI/TUI conversations (cron, subagents and gateways are refused); login is a manual command that registers its own OAuth client with clerk.mypenny.ai and briefly listens on 127.0.0.1 for the callback; tokens are kept in <HERMES_HOME>/penny/auth.json (owner-only) and are not removed on uninstall; no raw transcript upload, telemetry or other-client credential reuse.

How to install
- Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install penny - Said no? Turn it on later:
hermes plugins enable penny - Restart Hermes so it loads the plugin.
Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
