Gbrain Retrieval Reflex
pre_llm_call hook plugin, enabled with `hermes plugins enable`: injects ambient context from a GBrain instance before each turn (volunteer_context, then a hybrid-query fallback). Not a `memory.provider`. Silent no-op when GBrain is unreachable or no token is set.
Good to know before installing
Before each non-trivial turn the last six user and assistant messages (truncated) and the current message are sent with a GBRAIN_TOKEN bearer token to GBRAIN_MCP_URL (default http://127.0.0.1:3131/mcp), and returned brain-page text is injected into the turn.
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-retrieval-reflex - Said no? Turn it on later:
hermes plugins enable gbrain-retrieval-reflex - 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).
