OpenClaw - Mem0

Overview

The plugin provides:

  1. Triage: The agent extracts durable facts from conversations using a structured protocol with importance gates and domain overlays
  2. Recall: Before each turn, relevant memories are retrieved with reranking and injected into context
  3. Dream: Periodic memory consolidation merges duplicates, resolves conflicts, prunes stale entries
  4. Agent Tools: Eight tools for explicit memory operations during conversations

Skills mode, autoRecall, and autoCapture are all enabled by default during openclaw mem0 init.

Requirements

Check your OpenClaw version:

openclaw --version
# OpenClaw 2026.4.25 (aa36ee6)
OpenClaw Version Plugin Support
>= 2026.4.25 Fully supported

Installation

The fastest way is to install directly from your OpenClaw chat, no CLI or config editing needed. Copy and paste this into your OpenClaw chat; Telegram, WhatsApp, default chat, or any channel where your agent lives:

Setup Mem0 from mem0.ai/claw-setup

OpenClaw installs the plugin, prompts you for your email, and connects your Mem0 account with OTP verification. See Chat Setup below for the full walkthrough. If you prefer the OpenClaw CLI, or are setting up self-hosted / open-source mode, see Manual Config and Open-Source Mode below.

Setup and Configuration

Understanding userId

The userId field is a string you choose to uniquely identify the user whose memories are being stored. It is not something you look up in the Mem0 dashboard: you define it yourself. Pick any stable, unique identifier for the user. Common choices:

All memories are scoped to this userId: different values create separate memory namespaces. If you don’t set it, it defaults to your OS username.

In a multi-user application, set userId dynamically per user (e.g. from your auth system) rather than hardcoding a single value.

Platform Mode (Mem0 Cloud)

There are two ways to set up @mem0/openclaw-mem0 on the Mem0 platform:

Option 1: Chat Setup (Recommended)

You no longer need manual config editing to get started. Everything happens inside the OpenClaw chat itself.

  1. Send the setup command to your OpenClaw agent

Open any OpenClaw channel: Telegram, WhatsApp, your default chat, wherever your agent lives. Paste and send this command:

Setup Mem0 from mem0.ai/claw-setup

OpenClaw responds with a Mem0 setup card and immediately asks:

“What’s your email address? I’ll send you a verification code to connect your Mem0 account.”

  1. Enter your email

Type your email address and send it. Mem0 sends back:

“Check your email for a 6-digit code and paste it here.”

  1. Paste the OTP

Copy the 6-digit code from your email inbox and paste it into the chat. You’ll see the confirmation:

“Connected to Mem0.”

That’s it. No API key, no config file editing, no environment variables. The plugin is now active with skills-based memory (triage, recall, and dream) running automatically.

The chat flow uses the same underlying config as manual setup: it writes apiKey, userId, and skills config into openclaw.json for you. You can still open the file to inspect or override values afterward.

Option 2: Manual Config

  1. Install the plugin via the OpenClaw CLI
openclaw plugins install @mem0/openclaw-mem0
  1. Get your API key

Get your API key from app.mem0.ai.

  1. Select the plugin as your memory backend in openclaw.json

Add the full config to your openclaw.json:

{
  "plugins": {
    "slots": {
      "memory": "openclaw-mem0"
    },
    "entries": {
      "openclaw-mem0": {
        "enabled": true,
        "config": {
          "apiKey": "${MEM0_API_KEY}",
          "userId": "alice",  // any unique identifier you choose for this user
          "skills": {
            "triage": { "enabled": true },
            "recall": {
              "enabled": true,
              "tokenBudget": 1500,
              "rerank": true,
              "keywordSearch": true,
              "identityAlwaysInclude": true
            },
            "dream": { "enabled": true },
            "domain": "companion"
          }
        }
      }
    }
  }
}

OpenClaw treats memory plugins as an exclusive slot. Installing the plugin alone does not activate it: you must also set plugins.slots.memory as shown above.

Open-Source Mode (Self-hosted)

No Mem0 key is needed. Defaults use OpenAI (gpt-5-mini for LLM, text-embedding-3-small for embeddings), so OPENAI_API_KEY is required. For a fully local setup, use Ollama for both.

Option 1: Interactive Wizard (Recommended)

Run the guided 4-step wizard:

openclaw mem0 init --mode open-source

Option 2: Non-Interactive Setup

For CI/CD, scripts, or agent-driven setup: pass all options as flags:

# Fully local with Ollama + Qdrant
openclaw mem0 init --mode open-source \  
  --oss-llm ollama --oss-embedder ollama --oss-vector qdrant

# OpenAI + Qdrant
openclaw mem0 init --mode open-source \  
  --oss-llm openai --oss-llm-key <key> \  
  --oss-embedder openai --oss-embedder-key <key> \  
  --oss-vector qdrant

# Anthropic LLM + OpenAI embeddings + PGVector
openclaw mem0 init --mode open-source \  
  --oss-llm anthropic --oss-llm-key <key> \  
  --oss-embedder openai --oss-embedder-key <key> \  
  --oss-vector pgvector --oss-vector-user postgres --oss-vector-password secret

Add --json for machine-readable output (useful when an LLM agent is driving the setup).

Short-term vs Long-term Memory

Memories are organized into two scopes:

During auto-recall, the plugin searches both scopes and presents them separately, with long-term memories first and session memories second. This means the agent has full context.

Agent Tools

The agent gets eight tools it can call during conversations:

Tool Description
memory_search Search memories by natural language query. Supports scope, categories, filters.
memory_add Store facts. Accepts text or facts array, category, importance, metadata.
memory_get Retrieve a single memory by ID
memory_list List all memories. Filter by userId, agentId, scope.
memory_update Update a memory’s text in place. Preserves history.
memory_delete Delete by memoryId, query (search-and-delete), or all: true.
memory_event_list List recent background processing events (platform mode only).
memory_event_status Get status of a specific event by ID (platform mode only).

The memory_search and memory_list tools accept a scope parameter ("session", "long-term", or "all") to control which memories are queried.

CLI Commands

All commands support --json for machine-readable output. Use it when an LLM agent drives the CLI programmatically. Run openclaw mem0 help --json to discover every command and flag.

# Search all memories (long-term + session)
openclaw mem0 search "what languages does the user know"

# Search only long-term memories
openclaw mem0 search "what languages does the user know" --scope long-term

# Search only session/short-term memories
openclaw mem0 search "what languages does the user know" --scope session

# List all memories
openclaw mem0 list
openclaw mem0 list --user-id alice --top-k 20

# JSON output (any command)
openclaw mem0 search "preferences" --json
openclaw mem0 status --json

Configuration Options

General Options

Everything inside oss is optional: defaults use OpenAI embeddings (text-embedding-3-small), in-memory vector store, and OpenAI LLM (gpt-5-mini).

Plugin Management

Updating the Plugin

openclaw plugins update openclaw-mem0

Checking Plugin Status

openclaw plugins list
openclaw plugins inspect openclaw-mem0

Troubleshooting

”plugins.allow excludes mem0” Error

If you see an error like:

[openclaw] Failed to start CLI: Error: The `openclaw mem0` command is unavailable
because `plugins.allow` excludes "mem0". Add "mem0" to `plugins.allow` if you want
that bundled plugin CLI surface.

Add mem0 to your plugins.allow list in openclaw.json:

{
  "plugins": {
    "allow": ["mem0"],
    "slots": {
      "memory": "openclaw-mem0"
    }
  }
}

Plugin Not Activating

If the plugin installs but doesn’t work:

  1. Verify plugins.slots.memory is set to "openclaw-mem0" (not the npm package name)
  2. Check openclaw plugins list --enabled to confirm the plugin is loaded
  3. Run openclaw mem0 status to verify configuration

Plugin Update Not Working

If openclaw plugins update fails:

  1. Use the plugin ID: openclaw plugins update openclaw-mem0
  2. Update all plugins at once: openclaw plugins update --all
  3. If that fails, uninstall and reinstall:
openclaw plugins uninstall openclaw-mem0
openclaw plugins install @mem0/openclaw-mem0

Privacy & Security

Data Flow

Mode Where data goes Storage
Platform Conversations sent to api.mem0.ai for extraction and storage Mem0 cloud
Open-source Embeddings generated via configured provider (default: OpenAI API). Vectors stored locally. ~/.mem0/vector_store.db (SQLite)

Auto-Capture and Auto-Recall

Auto-capture and auto-recall are enabled by default. When skills mode is configured (the default after openclaw mem0 init), these are ignored in favor of the skills-based triage/recall/dream protocol. To disable either:

{
  "plugins": {
    "entries": {
      "openclaw-mem0": {
        "config": {
          "autoCapture": false,   // disable automatic fact extraction
          "autoRecall": false     // disable automatic memory injection
        }
      }
    }
  }
}

The agent can always use memory tools (memory_add, memory_search, etc.) explicitly regardless of these settings.

Credential Protection

The plugin never stores API keys, tokens, or secrets as memories. Five independent layers enforce this:

  1. Triage gate: The extraction prompt rejects values matching known credential patterns (sk-, m0-, ghp_, AKIA, Bearer, password=, token=, secret=)
  2. Dream cleanup: Periodic memory consolidation deletes any memories that slipped through containing credential patterns
  3. Extraction instructions: Default extraction rules explicitly instruct the model to store only that a credential was configured, never the value
  4. Configurable patterns: Add custom credential patterns via skills.triage.credentialPatterns
  5. CLI redaction: openclaw mem0 config show redacts sensitive fields (apiKey, oss.*.config.apiKey)

API Key Storage

Plugin config is stored in ~/.openclaw/openclaw.json with file permissions 0o600 (owner-read-only). For production deployments, use environment variable references (${MEM0_API_KEY}) or SecretRef objects instead of plaintext keys.

Telemetry

Anonymous usage telemetry (PostHog) is enabled by default to help improve the plugin. No conversation content or memory values are included, only event counts (recall, capture, tool usage, CLI commands). To opt out, set the environment variable:

export MEM0_TELEMETRY=false

System Prompt Context

The plugin injects memory-related instructions into the agent’s system context via OpenClaw’s prependSystemContext mechanism. This includes the memory triage protocol and recalled memories. This is the standard OpenClaw plugin SDK pattern for memory backends.
