Memory (MemoryLake)
MemoryLake memory backend for OpenClaw
Install
openclaw plugins install clawhub:memorylake-openclawmemorylake-openclaw
Long-term memory for OpenClaw agents, powered by MemoryLake.
Your agent forgets everything between sessions. This plugin fixes that. It watches conversations, extracts what matters, and brings it back when relevant — automatically.
How it works
Auto-Recall — Before the agent responds, the plugin injects memory-search instructions and open-data categories into the system prompt, instructing the agent to call retrieve_context before every reply.
Auto-Capture — After the agent responds, the plugin sends the exchange to MemoryLake. MemoryLake decides what's worth keeping — new facts get stored, stale ones updated, duplicates merged.
Auto-Upload — When a user sends a file (image, document, etc.), the plugin uploads it to MemoryLake as a project document.
Auto-Recall, Auto-Capture, and Auto-Upload run silently by default.
Setup
openclaw plugins install memorylake-openclaw
Get an API key from app.memorylake.ai, then add to your openclaw.json:
// plugins.entries
"memorylake-openclaw": {
"enabled": true,
"config": {
"apiKey": "sk-...",
"projectId": "proj-..."
}
}
Agent tools
The agent gets seven tools it can call during conversations:
| Tool | Description |
|---|---|
retrieve_context | Search memories AND uploaded documents in a single call |
memory_list | List all stored memories for a user |
memory_store | Explicitly save a fact |
memory_forget | Delete a memory by ID |
document_download | Download a document by ID (returns a presigned URL) |
advanced_web_search | Optional tool for web search with plugin-level domain and locale constraints |
open_data_search | Search open data sources scoped to the project's configured industry categories |
CLI
