maasv Memory

maasv Memory

Structured long-term memory for OpenClaw agents, powered by maasv.

Replaces the default memory backend with a cognition layer that includes 3-signal retrieval (semantic + keyword + knowledge graph), entity extraction, temporal versioning, and experiential learning.

maasv is entirely self-hosted. There is no maasv cloud service. You run the server on your own machine, and all data is stored in a SQLite file on your local disk that you own and control. Nothing is sent to maasv.

Install

This skill requires the @maasv/openclaw-memory plugin and a running maasv server.

1. Start the server

pip install "maasv[server,anthropic,voyage]"
cp server.env.example .env  # fill in API keys (see below)
maasv-server

2. Install the plugin

openclaw plugins install @maasv/openclaw-memory

3. Activate

// ~/.openclaw/openclaw.json
{
  plugins: {
    slots: { memory: "memory-maasv" },
    entries: {
      "memory-maasv": {
        enabled: true,
        config: {
          serverUrl: "http://127.0.0.1:18790",
          autoRecall: true,
          autoCapture: true,
          enableGraph: true
        }
      }
    }
  }
}

Required Credentials

The maasv server needs an LLM provider (for entity extraction) and an embedding provider (for semantic search). Configure these in your .env file:

For fully local operation (no cloud calls), use ollama as your embed provider and a local LLM. maasv is optimized for Qwen3-Embedding-8B via Ollama, with built-in Matryoshka dimension truncation. See the maasv README for local setup.

Data & Network Behavior

• maasv has no cloud service. The server runs on your machine, the database is a SQLite file on your disk. You own all of it.
• The only external calls are to your own LLM/embedding provider (Anthropic, OpenAI, Voyage) — using your own API keys, from your own machine. If you use ollama, zero data leaves your machine.
• The plugin talks only to localhost (127.0.0.1:18790). It makes no external network calls.
• autoCapture sends conversation summaries to your local maasv server for entity extraction. Extracted entities are stored in your local SQLite database.
• autoRecall reads from your local SQLite database and injects relevant memories into the agent's context.
• No telemetry, no analytics, no phone-home. maasv does not collect or transmit any data.

What You Get

• memory_search — 3-signal retrieval across your memory store
• memory_store — Dedup-aware memory storage
• memory_forget — Permanent deletion
• memory_graph — Knowledge graph: entity search, profiles, relationships
• memory_wisdom — Log reasoning, record outcomes, search past decisions
