Persistent memory for agents, shared across tools: save preferences, decisions and lessons and recall them later by natural-language search; rating a recalled memory as helpful or misleading re-ranks what comes back next; shared rooms (beta) let several people's agents work from one memory. Portable Agent Plugins v1 package (plugin.json + mcp.json + skills/) pointing at the hosted Mnemoverse MCP server (Streamable HTTP, OAuth 2.1 + DCR); the two bundled skills load under a namespaced name.

## Good to know before installing

Hosted-only connector; Hermes runs no code from the package (scripts/ holds the repository's own CI checks). Every tool call goes to the vendor's remote MCP server at mcp.mnemoverse.com (authorization server auth.mnemoverse.com, browser sign-in on console.mnemoverse.com); memories the agent writes are stored in the signed-in user's Mnemoverse account, and recalled memories are pulled into the session context. OAuth tokens are held and refreshed by Hermes, never by the package. No telemetry, background process or self-update code.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install mnemoverse
```

2. Said no? Turn it on later:

```bash
hermes plugins enable mnemoverse
```

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
