@mem0/openclaw-mem0

Long-term memory for OpenClaw agents, powered by Mem0.

Your agent forgets everything between sessions. This plugin fixes that — it stores conversations, extracts what matters, and brings it back when relevant.

By default, the plugin runs in skills mode: the agent controls what to remember (triage), how to recall (recall), and periodic cleanup (dream). 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

Quick Start

Platform (Mem0 Cloud)

Install and Configure

1. Install the plugin via the OpenClaw CLI:

   openclaw plugins install @mem0/openclaw-mem0
   

2. Get your API key from app.mem0.ai.

3. Select the plugin as your memory backend in openclaw.json. Either initialize via the CLI:

   openclaw mem0 init --api-key <your-key> --user-id <your-user-id>
   

   Or 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",
             "skills": {
               "triage": { "enabled": true },
               "recall": {
                 "enabled": true,
                 "tokenBudget": 1500,
                 "rerank": true,
                 "keywordSearch": true,
                 "identityAlwaysInclude": true
               },
               "dream": { "enabled": true },
               "domain": "companion"
             }
           }
         }
       }
     }
   }
   

Note: OpenClaw memory plugins load through an exclusive slot, so install alone does not activate the plugin. You must set plugins.slots.memory as shown above.

Updating the plugin to get the latest features and fixes:

openclaw plugins update openclaw-mem0

Open-Source (Self-hosted)

No Mem0 key needed. Vectors are stored locally in SQLite at ~/.mem0/vector_store.db — no external database required.

Defaults: text-embedding-3-small (OpenAI) for embeddings, gpt-5-mini (OpenAI) for fact extraction — requires OPENAI_API_KEY. For a fully local setup, use Ollama for both LLM and embeddings.

Interactive Setup (Recommended)

Run the guided 4-step wizard:

openclaw mem0 init --mode open-source

The wizard walks you through:

1. LLM provider — OpenAI (gpt-5-mini), Ollama (llama3.1:8b, local), or Anthropic (claude-sonnet-4-5-20250514)
2. Embedding provider — OpenAI (text-embedding-3-small) or Ollama (nomic-embed-text, local)
3. Vector store — Qdrant (http://localhost:6333) or PGVector (PostgreSQL)
4. User ID — your memory namespace identifier

Each step tests connectivity (Ollama, Qdrant, PGVector) before proceeding.

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

# JSON output (for LLM agents)
openclaw mem0 init --mode open-source --oss-llm ollama --oss-embedder ollama --oss-vector qdrant --json

Manual Config

Minimal config — uses OpenAI defaults:

{
  "plugins": {
    "slots": {
      "memory": "openclaw-mem0"
    },
    "entries": {
      "openclaw-mem0": {
        "enabled": true,
        "config": {
          "mode": "open-source",
          "userId": "alice"
        }
      }
    }
  }
}

Customize the embedder, vector store, or LLM via the oss block:

"config": {
  "mode": "open-source",
  "userId": "alice",
  "oss": {
    "embedder": { "provider": "openai", "config": { "model": "text-embedding-3-small" } },
    "vectorStore": { "provider": "qdrant", "config": { "url": "http://localhost:6333" } },
    "llm": { "provider": "openai", "config": { "model": "gpt-5-mini" } }
  }
}

All oss fields are optional. See the Mem0 OSS docs for supported providers.

How It Works

Skills Mode (Default)

Enabled automatically during openclaw mem0 init. The agent controls memory through three skills:

• Triage — Extracts durable facts from conversations using a structured protocol. Categories, importance gates, and domain overlays control what gets stored.
• Recall — Before each turn, rewrites the user message into search queries, retrieves relevant memories with reranking, and injects them into context.
• Dream — Periodic memory consolidation: merges duplicates, resolves conflicts, and prunes stale entries.

When skills mode is active, the skills handle memory operations. autoRecall and autoCapture remain true by default alongside skills mode. The built-in session-memory hook is disabled to avoid conflicts.

Auto-Recall & Auto-Capture

When skills mode is not configured, the plugin uses autoRecall and autoCapture (both enabled by default):

• Auto-Recall — Before the agent responds, the plugin searches Mem0 for relevant memories and injects them into context.
• Auto-Capture — After the agent responds, the conversation is filtered through a noise-removal pipeline and sent to Mem0. New facts get stored, stale ones updated, duplicates merged.

Set autoRecall: false or autoCapture: false to disable individually. The agent can also use memory tools (memory_add, memory_search, etc.) explicitly regardless of these settings.

Memory Scopes

• Session (short-term) — Scoped to the current conversation via run_id. Recalled alongside long-term memories.
• User (long-term) — Persistent across all sessions. Default for memory_add.

Multi-Agent Isolation

Each agent gets its own memory namespace automatically via session key routing (agent:<name>:<uuid> maps to userId:agent:<name>). Single-agent setups are unaffected.

Agent Tools

Eight tools are registered for agent use:

Tool	Description
memory_search	Search by natural language query. Supports scope (session, long-term, all), categories, filters, and agentId.
memory_add	Store facts. Accepts text or facts array, category, importance, longTerm, 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 (requires confirm: 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.

CLI

All commands: openclaw mem0 <command>. All commands support --json for machine-readable output (for LLM agents).

# Memory operations
openclaw mem0 add "User prefers TypeScript over JavaScript"
openclaw mem0 search "what languages does the user know"
openclaw mem0 search "preferences" --scope long-term
openclaw mem0 get <memory_id>

Privacy & Security

Data Flow

Mode	Where data goes	Credentials needed
Platform	Conversations sent to api.mem0.ai for memory extraction and retrieval	MEM0_API_KEY
Open-Source (OpenAI)	LLM/embedding calls to OpenAI API; vectors stored locally at ~/.mem0/vector_store.db	OPENAI_API_KEY
Open-Source (Ollama)	Fully local — LLM, embeddings, and vectors all on your machine	None

Credential Storage

The plugin stores configuration in ~/.openclaw/openclaw.json. If you use the chat setup flow or openclaw mem0 init, your API key and user ID are written to this file.

To avoid plaintext credentials:

• Use env var references: "apiKey": "${MEM0_API_KEY}"
• Use SecretRef: "apiKey": {"source": "env", "provider": "default", "id": "MEM0_API_KEY"}

Memory Processing

In skills mode (default after openclaw mem0 init), the agent uses structured protocols (triage, recall, dream) to decide what to store and recall. The built-in session-memory hook is disabled to avoid conflicts.

Without skills, autoCapture and autoRecall are both enabled by default:

• autoCapture: sends conversation content to your configured backend after each agent turn
• autoRecall: queries your memory store before each agent turn and injects results into context

In platform mode, conversation content is sent to api.mem0.ai for processing. Do not use with sensitive data you do not want stored on Mem0 cloud.

Persistence Locations

File	Purpose
~/.openclaw/openclaw.json	Plugin configuration (API keys, user ID, settings)
~/.mem0/vector_store.db	Local vector store (open-source mode only)
~/.mem0/history.db	Memory edit history (open-source mode only)
<pluginStateDir>/dream-state.json	Memory consolidation state
