OpenClaw MemX Memory Plugin

Skill by ara.so — Hermes Skills collection.

OpenClaw MemX is a local-first long-term memory plugin that enables AI agents to maintain working memory across days, projects, and conversations. It provides stable work memory, task state tracking, relationship-aware recall, learned habits, automatic cleanup, and compact evidence injection.

Key Capabilities

• Long-term memory: Remembers project decisions, user preferences, task status, and important events
• Relationship graphs: Tracks how projects, repos, tools, people, and resources relate to each other
• Self-learning: Notices stable patterns across repeated work (e.g., user preferences, recurring workflows)
• Self-maintenance: Consolidates repeated evidence, replaces corrected information, cleans up old task state
• Smart recall: Searches across facts, events, state, chunks, relationships, and patterns to inject relevant evidence

Installation

Prerequisites

• OpenClaw 2026.3.25 or later
• Node.js 22.14+ or Node 24
• Python 3 (only required for local embeddings)

Configuration

Setup with Local Embeddings

The recommended configuration uses local sentence-transformers for embeddings:

# Create Python virtual environment for embeddings
python3 -m venv "$HOME/.openclaw/memx/.venv"
"$HOME/.openclaw/memx/.venv/bin/python" -m pip install -U pip sentence-transformers torch

# Setup MemX with local embeddings
openclaw memx setup \
  --local-embedding \
  --embedding-python "$HOME/.openclaw/memx/.venv/bin/python"

Setup with LLM Provider (DeepSeek Example)

# Configure LLM provider (use environment variable for API key)
export DEEPSEEK_API_KEY="your-api-key-here"

openclaw config set models.providers.deepseek '{
  "api": "openai-completions",
  "baseUrl": "https://api.deepseek.com",
  "apiKey": "${DEEPSEEK_API_KEY}",
  "models": [
    {
      "id": "deepseek-v4-flash",
      "name": "DeepSeek V4 Flash",
      "api": "openai-completions",
      "reasoning": false,
      "input": ["text"],
      "cost": { "input": 0, "output": 0, "cacheRead": 0, "cacheWrite": 0 },
      "contextWindow": 64000,
      "maxTokens": 8192
    }
  ]
}' --strict-json

# Setup MemX with LLM model and local embeddings
openclaw memx setup \
  --local-embedding \
  --embedding-python "$HOME/.openclaw/memx/.venv/bin/python" \
  --llm-model deepseek/deepseek-v4-flash

openclaw gateway restart

Alternative Embedding Providers

OpenAI-compatible embeddings:

export EMBEDDING_API_KEY="your-embedding-key"

openclaw memx setup \
  --embedding-provider openai-compatible \
  --embedding-model text-embedding-3-small

openclaw config set plugins.entries.memory-memx.config.embedding.baseURL https://api.openai.com/v1
openclaw config set plugins.entries.memory-memx.config.embedding.apiKey '${EMBEDDING_API_KEY}'

Ollama embeddings:

openclaw memx setup \
  --embedding-provider ollama \
  --embedding-model nomic-embed-text

openclaw config set plugins.entries.memory-memx.config.embedding.ollamaBaseURL http://127.0.0.1:11434

Custom local model:

python3 -m pip install --user sentence-transformers torch

openclaw memx setup \
  --embedding-provider sentence-transformers-local \
  --embedding-model BAAI/bge-m3 \
  --embedding-device auto

Disable embeddings (lexical fallback only):

openclaw memx setup --embedding-provider off

Reindex After Configuration Changes

After changing embedding settings, restart the gateway and reindex existing memories:

openclaw gateway restart
openclaw memx reindex

Key Commands

Setup and Maintenance

# Initial setup with local embeddings
openclaw memx setup --local-embedding

# Setup with specific embedding Python runtime
openclaw memx setup --local-embedding --embedding-python /path/to/.venv/bin/python

# Setup with specific LLM model
openclaw memx setup --llm-model provider/model

# Verify installation and configuration
openclaw memx doctor

# Deep verification with embedding and LLM tests
openclaw memx doctor --deep

# Reindex all memories (after embedding provider change)
openclaw memx reindex

# Restart gateway after configuration changes
openclaw gateway restart

Memory Operations

MemX operates automatically through OpenClaw's memory slot system. The plugin:

• Automatically stores relevant information from conversations
• Recalls relevant memories when needed
• Injects memory context into prompts
• Maintains and consolidates memory over time

Compatibility Mode

By default, MemX does not expose legacy memory_search and memory_get tools. To enable compatibility tools:

openclaw config set plugins.entries.memory-memx.config.advanced.enableCompatibilityMemoryTools true
openclaw gateway restart

What memx setup Configures

The openclaw memx setup command writes the recommended configuration:

1. Adds memory-memx to plugins.allow
2. Sets plugins.slots.memory to memory-memx (MemX owns the memory slot)
3. Enables plugins.entries.memory-memx.hooks.allowPromptInjection (memory injection)
4. Enables turn scheduler and LLM semantic compiler
5. Keeps advanced.enableCompatibilityMemoryTools=false (no legacy tools by default)
6. Configures requested embedding provider and model

Note: memx setup does not delete or migrate existing MEMORY.md files. MemX's recall context tells the agent not to treat MEMORY.md or memory/*.md as the active memory backend unless explicitly asked.

Architecture Overview

MemX maintains several types of memory:

• Facts: Stable information about preferences, decisions, and learned patterns
• Events: Time-stamped occurrences tied to specific contexts
• Task State: Current status of ongoing work
• Chunks: Segmented conversation turns for precise recall
• Relationships: Connections between entities (projects, repos, tools, people)
• Resources: References to files, documentation, links

All memories are tied to supporting evidence and are automatically maintained over time.

TypeScript Integration Examples

Checking MemX Installation Status

import { execSync } from 'child_process';

function checkMemXInstallation(): boolean {
  try {
    const result = execSync('openclaw memx doctor', { encoding: 'utf-8' });
    return result.includes('MemX is ready');
  } catch (error) {
    console.error('MemX not properly installed:', error);
    return false;
  }
}

Verifying Memory Configuration

import { execSync } from 'child_process';

function verifyMemXConfig(): void {
  try {
    // Check if memory slot is assigned to MemX
    const config = execSync('openclaw config get plugins.slots.memory', { encoding: 'utf-8' });
    
    if (config.trim() === 'memory-memx') {
      console.log('✓ MemX is active memory provider');
    } else {
      console.warn('⚠ MemX is not the active memory provider');
    }
  } catch (error) {
    console.error('Failed to check MemX configuration:', error);
  }
}

Programmatic Setup Script

import { execSync } from 'child_process';
import * as fs from 'fs';
import * as path from 'path';

interface MemXSetupOptions {
  embeddingProvider?: 'local' | 'openai' | 'ollama' | 'off';
  llmModel?: string;
  embeddingPython?: string;
}

function setupMemX(options: MemXSetupOptions = {}): void {
  const {
    embeddingProvider = 'local',
    llmModel,
    embeddingPython
  } = options;

  try {
    // Install Python dependencies for local embeddings
    if (embeddingProvider === 'local') {
      console.log('Installing Python dependencies...');
      const pythonBin = embeddingPython || 'python3';
      execSync(`${pythonBin} -m pip install --user sentence-transformers torch`, {
        stdio: 'inherit'
      });
    }

    // Build setup command
    let setupCmd = 'openclaw memx setup';
    
    if (embeddingProvider === ) {
      setupCmd += ;
       (embeddingPython) {
        setupCmd += ;
      }
    }   (embeddingProvider === ) {
      setupCmd += ;
    }
    
     (llmModel) {
      setupCmd += ;
    }

    .();
    (setupCmd, { :  });

    
    .();
    (, { :  });

    
    .();
    (, { :  });

    .();
  }  (error) {
    .(, error);
     error;
  }
}

Common Patterns

Initial Setup for New OpenClaw Installation

# 1. Install OpenClaw (if not already installed)
# 2. Configure an LLM provider
export LLM_API_KEY="your-api-key"

openclaw config set models.providers.yourprovider '{
  "api": "openai-completions",
  "baseUrl": "https://api.provider.com",
  "apiKey": "${LLM_API_KEY}",
  "models": [
    {
      "id": "model-id",
      "name": "Model Name",
      "api": "openai-completions",
      "reasoning": false,
      "input": ["text"],
      "cost": { "input": 0, "output": 0 },
      "contextWindow": 32000,
      "maxTokens": 4096
    }
  ]
}' --strict-json

# 3. Install and setup MemX
git clone https://github.com/NeoLi00/openclaw-memx.git
cd openclaw-memx
openclaw plugins install .

python3 -m venv "$HOME/.openclaw/memx/.venv"
"$HOME/.openclaw/memx/.venv/bin/python" -m pip install -U pip sentence-transformers torch

openclaw memx setup \
  --local-embedding \
  --embedding-python "$HOME/.openclaw/memx/.venv/bin/python" \
  --llm-model yourprovider/model-id

openclaw gateway restart
openclaw memx doctor --deep

Switching Embedding Providers

# Switch from local to OpenAI embeddings
export EMBEDDING_API_KEY="your-key"

openclaw memx setup \
  --embedding-provider openai-compatible \
  --embedding-model text-embedding-3-small

openclaw config set plugins.entries.memory-memx.config.embedding.apiKey '${EMBEDDING_API_KEY}'
openclaw gateway restart
openclaw memx reindex

Migrating from Legacy Memory

# 1. MemX does not auto-migrate MEMORY.md
# 2. Manually review and convert important content:
#    - Have a conversation with the agent about the content
#    - Important facts will be automatically stored by MemX
# 3. Archive old memory files
mkdir -p legacy-memory
mv MEMORY.md memory/*.md legacy-memory/ 2>/dev/null || true

Troubleshooting

MemX Doctor Reports Issues

# Run deep diagnostics
openclaw memx doctor --deep

# Common issues and fixes:

# Issue: Memory slot not assigned to MemX
openclaw memx setup --local-embedding
openclaw gateway restart

# Issue: Embedding model not available
python3 -m pip install --user sentence-transformers torch

# Issue: LLM model not configured
openclaw config set plugins.entries.memory-memx.config.advanced.llmClassifierModel provider/model
openclaw gateway restart

# Issue: Plugin not in allow list
openclaw config set plugins.allow '["memory-memx"]' --json
openclaw gateway restart

Embedding Errors

# Check Python dependencies
python3 -c "import sentence_transformers; print(sentence_transformers.__version__)"

# Reinstall dependencies
python3 -m pip install --user --force-reinstall sentence-transformers torch

# Use specific Python runtime
openclaw memx setup --local-embedding --embedding-python /path/to/python

# Switch to different provider if local embeddings fail
openclaw memx setup --embedding-provider ollama --embedding-model nomic-embed-text
openclaw gateway restart

Memory Not Being Recalled

# Verify memory slot ownership
openclaw config get plugins.slots.memory
# Should return: memory-memx

# Verify prompt injection is enabled
openclaw config get plugins.entries.memory-memx.hooks.allowPromptInjection
# Should return: true

# Check if memories exist
openclaw memx doctor --deep
# Look for "stored memories" count

# Force reindex
openclaw memx reindex

Gateway Restart Issues

# Stop and restart cleanly
openclaw gateway stop
sleep 2
openclaw gateway start

# Check gateway logs
openclaw gateway logs

# Verify plugin loaded
openclaw plugins list
# Should show memory-memx as active

High Memory Usage

# MemX automatically maintains memory
# To manually trigger maintenance (advanced):
# Contact: [e-mail] for maintenance configuration

# Check memory database size
ls -lh ~/.openclaw/memory-memx/
# Typical size varies with usage

Best Practices

1. Use local embeddings for cost efficiency and privacy (intfloat/multilingual-e5-small recommended)
2. Run memx doctor --deep after any configuration change
3. Always restart the gateway after memx setup or config changes
4. Use environment variables for API keys, not hardcoded values
5. Reindex after changing embedding providers
6. Let MemX maintain itself — avoid manual memory file editing
7. Archive MEMORY.md files after migration to avoid confusion

Memory Storage Location

MemX stores memory data locally in:

~/.openclaw/memory-memx/

This includes:

• SQLite database with memories and relationships
• Vector embeddings index
• Configuration snapshots
