# Build a self-updating agent memory graph with GBrain

Use GBrain to give OpenClaw or Hermes-style agents a local knowledge brain with markdown ingestion, entity links, hybrid search, scheduled consolidation, and MCP access.

## Prerequisites

GBrain CLI, Bun/Node-compatible runtime, PGLite or Postgres with pgvector, markdown knowledge base, optional MCP server deployment

## Installation

Requirements and caveats from upstream:
- gbrain init --pglite # 2 seconds; no server, no Docker
- Run bun run test for the fast loop, bun run verify for the pre-push gate, bun run ci:local to run the full Docker-backed CI stack locally. Detailed test discipline in [CONTRIBUTING.md](CONTRIBUTING.md).

Basic usage or getting-started notes:

- GBrain runs in three shapes. Pick the one that matches how you use AI agents today.
