Native XMemo memory provider for Hermes Agent — durable, identity-aware cross-session memory with semantic search.

## Good to know before installing

Cloud memory provider: sends each user prompt (for recall and the search tools), model-written memories and mirrored built-in Hermes memory writes, plus a stable install ID, to xmemo.dev (Yonro Co., Ltd.); keeps a local SQLite cache of recalled results and a queue of unsent writes in $HERMES_HOME/xmemo_cache.db, partitioned by a hashed account identity; reads the key from XMEMO_KEY (also MEMORY_OS_API_KEY / MEMORY_OS_MCP_TOKEN) and, if none is set, falls back to the xmemo login token in ~/.config/xmemo/credentials.json (a catalog rule 11 deviation kept for existing users); workflow and destructive tools and timeline capture are off by default and opt-in.

From the plugin's catalog listing.

## How to install

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

```bash
hermes plugins install xmemo
```

2. Said no? Turn it on later:

```bash
hermes plugins enable xmemo
```

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
