Hermes Integrates Open-Source Second Brain Gbrain
dr_cintas · x · 2026-07-18
Using the Hermes Agent, the author set up a "second brain" powered by the open-source project Gbrain.
It integrates meeting notes and documents into its memory, keeping track of people, companies, projects, and decisions, while providing source citations for every answer. The author also shares the actual installation process: run the install command in Hermes, then add Gbrain's MCP server so Hermes can call it directly.
Key project features include:
- Graph-based memory and schema matching, rather than simple vector retrieval
- According to the author, it is 31 points more accurate than standard vector search on their internal benchmark
- Runs locally, serverless, and requires no Docker
- Open-source, making it ideal for personal knowledge bases or as a reference for an Agent memory layer
