Xmemo

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.

How to install

Install it. Hermes asks for any API keys it needs (this one needs XMEMO_KEY), then asks whether to turn it on.
hermes plugins install xmemo
Said no? Turn it on later:
hermes plugins enable xmemo
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).
