Gbrain Plugin
Community (non-official) plugin wiring GBrain (garrytan/gbrain, MIT) into Hermes as a local memory layer over MCP: /gbrain status command, desktop starter, and per-profile Postgres setup/update/maintenance scripts. Not affiliated with upstream.
Good to know before installing
The plugin itself only adds a /gbrain status command and a Desktop pane; GBrain is installed by the user via scripts/setup.sh, which installs bun (curl|bash), an unpinned gbrain from GitHub HEAD, and provisions PostgreSQL with sudo.
From the plugin's catalog listing.
How to install
- Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install gbrain-plugin - Said no? Turn it on later:
hermes plugins enable gbrain-plugin - 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).
