Long-term memory for you and your AI from Membase (membase.com, by Unibase): one memory every connected AI shares. Searches the user's Membase memory before each turn (8 s, fail-open) and adds membase_search, membase_save and membase_profile.

## Good to know before installing

User prompts are sent as search queries to the Membase API (api.app.membase.com); with the opt-in capture_turns setting the user's messages are saved there too, and what Hermes' built-in memory records about the user is saved to their Membase profile. MEMBASE_API_KEY comes from the Hermes secret scope; the only local file is $HERMES_HOME/unibaseio-membase.json. No background processes, shell commands or telemetry.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs (this one needs `MEMBASE_API_KEY`), then asks whether to turn it on.

```bash
hermes plugins install unibaseio-membase
```

2. Said no? Turn it on later:

```bash
hermes plugins enable unibaseio-membase
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
