What it is
memory-lancedb-pro is a LanceDB-backed OpenClaw memory plugin that stores preferences, decisions, and project context, then auto-recalls them in future sessions. It supports hybrid retrieval (vector + BM25) with a cross-encoder rerank, multi-scope isolation, and a CLI for management.
How it works
The plugin exposes two coordinated stores: Plugin Memory (LanceDB vector store) for semantic recall, and Canonical Corpus (files like MEMORY.md and memory/**/*.md) indexed semantically when enabled. Public artifacts and session transcripts can be indexed for retrieval. Retrieval results include path, startLine, endLine, snippet, source, and citation. Dreaming compatibility can reuse the memory core alongside public artifacts. OpenClaw interactions involve registering memory capabilities and validating/restarting gateways.
Getting started
Option A: One-Click Install Script (Recommended)
curl -fsSL https://raw.githubusercontent.com/CortexReach/toolbox/main/memory-lancedb-pro-setup/setup-memory.sh -o setup-memory.sh
bash setup-memory.sh
Option B: Manual Install
Via OpenClaw CLI (recommended):
openclaw plugins install memory-lancedb-pro@beta
Or via npm:
npm i memory-lancedb-pro@beta
Add to openclaw.json as shown in the README, with defaults such as embedding provider, apiKey, model, autoCapture, autoRecall, smartExtraction, canonicalCorpus, dreaming, extractMinMessages, extractMaxChars, and sessionMemory settings.
Validate and restart after installation:
openclaw config validate
openclaw gateway restart
openclaw logs --follow --plain | grep "memory-lancedb-pro"
