Lovefromio Openclaw Persistent Memory

Persistent memory system - automatic context capture and semantic search

OpenClaw Persistent Memory

Persistent memory system that automatically captures context across sessions using SQLite + FTS5.

Features

• 🧠 Auto-capture - Important observations saved automatically after each response
• 🔍 Auto-recall - Relevant memories injected before each prompt
• 💾 SQLite + FTS5 - Fast full-text search across all memories
• 🛠️ Tools - memory_search, memory_get, memory_store, memory_delete
• 📊 Progressive disclosure - Token-efficient retrieval

Setup

1. Install the npm package:

   bash

   npm install -g openclaw-persistent-memory
   

2. Start the worker service:

   bash

   openclaw-persistent-memory start
   

3. Install the OpenClaw extension:

   bash

   # Copy extension to OpenClaw extensions directory
   cp -r node_modules/openclaw-persistent-memory/extension ~/.openclaw/extensions/openclaw-mem
   cd ~/.openclaw/extensions/openclaw-mem && npm install
   

4. Configure OpenClaw (in ~/.openclaw/openclaw.json):

   json

   {
     "plugins": {
       "slots": {
         "memory": "openclaw-mem"
       },
       "allow": ["openclaw-mem"],
       "entries": {
         "openclaw-mem": {
           "enabled": true,
           "config": {
             "workerUrl": "http://127.0.0.1:37778",
             "autoCapture": true,
             "autoRecall": true
           }
         }
       }
     }
   }
   

5. Restart OpenClaw gateway

Troubleshooting

Worker not running

bash

curl http://127.0.0.1:37778/api/health
# If fails, restart:
openclaw-persistent-memory start

Auto-recall not working

• Check OpenClaw logs: tail ~/.openclaw/logs/*.log | grep openclaw-mem
• Verify plugins.slots.memory is set to "openclaw-mem"
• Restart gateway after config changes
