memorylake-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

# Search memories
openclaw memorylake search "what languages does the user know"

# Upload files or directories
openclaw memorylake upload /path/to/file.pdf

# Stats
openclaw memorylake stats

Options

| Key | Type | Default | | |-----|------|---------|---| | apiKey | string | — | Required. MemoryLake API key (supports ${MEMORYLAKE_API_KEY}) | | projectId | string | — | Required. MemoryLake project ID | | host | string | https://app.memorylake.ai | MemoryLake server endpoint URL | | autoRecall | boolean | true | Inject mandatory retrieve_context instructions before each turn | | autoCapture | boolean | true | Store facts after each turn | | autoUpload | boolean | true | Auto-upload inbound files to MemoryLake | | topK | number | 5 | Max memories per recall | | searchThreshold | number | 0.3 | Min similarity (0–1) | | rerank | boolean | true | Rerank search results | | webSearchIncludeDomains | string[] | — | Optional allowlist for advanced_web_search results | | webSearchExcludeDomains | string[] | — | Optional denylist for advanced_web_search results | | webSearchCountry | string | — | Optional ISO country code for localizing advanced_web_search | | webSearchTimezone | string | — | Optional IANA timezone for localizing advanced_web_search |

advanced_web_search is registered as an optional OpenClaw tool, so agents must explicitly allow it before they can call it.
