Honcho is memory infrastructure for building stateful agents that understand changing people, agents, groups, projects, and ideas over time. Store messages and events, let Honcho reason in the background, then query peer representations, session context, search results, or natural-language insights from any model or framework. Use it managed at api.honcho.dev, run a local stack with the honcho CLI, or self-host the server yourself. Maintained by Plastic Labs; the same provider that shipped in-tree.

## Good to know before installing

Conversation turns, derived conclusions and peer/session ids are sent to the Honcho API (api.honcho.dev by default, or the self-hosted base_url you configure) under your HONCHO_API_KEY; every request also carries X-Honcho-Host (Hermes version and OS platform) and X-Honcho-Plugin (plugin version) headers that Honcho records for usage attribution.

From the plugin's catalog listing.

## How to install

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

```bash
hermes plugins install honcho
```

2. Said no? Turn it on later:

```bash
hermes plugins enable honcho
```

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
