Your OpenClaw agents remember everything. No more re-explaining.
_{Persistent cross-session memory via agentmemory — 95.2% retrieval accuracy on LongMemEval-S.}

Paste this prompt into OpenClaw and it does the whole setup for you:

Install agentmemory for OpenClaw. Run `npx @agentmemory/agentmemory` in a separate terminal to start the memory server on localhost:3111.

For zero-code setup, add this MCP server so OpenClaw gets all 43 memory tools:

{
  "mcpServers": {
    "agentmemory": {
      "command": "npx",
      "args": ["-y", "@agentmemory/mcp"]
    }
  }
}

For deeper memory integration, copy `integrations/openclaw` from the agentmemory repo to `~/.openclaw/extensions/agentmemory`, then enable it in `~/.openclaw/openclaw.json`:

{
  "plugins": {
    "slots": {
      "memory": "agentmemory"
    },
    "entries": {
      "agentmemory": {
        "enabled": true,
        "config": {
          "base_url": "http://localhost:3111",
          "token_budget": 2000,
          "min_confidence": 0.5,
          "fallback_on_error": true,
          "timeout_ms": 5000
        }
      }
    }
  }
}

Restart OpenClaw. Verify with `curl http://localhost:3111/agentmemory/health`. Open http://localhost:3113 for the real-time viewer.

That's it. OpenClaw handles the rest.

Start the agentmemory server in a separate terminal:

npx @agentmemory/agentmemory

Then add to your OpenClaw MCP config:

{
  "mcpServers": {
    "agentmemory": {
      "command": "npx",
      "args": ["-y", "@agentmemory/mcp"]
    }
  }
}

OpenClaw now has access to all 43 MCP tools including memory_recall, memory_save, memory_smart_search, memory_timeline, memory_profile, and more.

Copy this folder into OpenClaw's extension directory:

mkdir -p ~/.openclaw/extensions
cp -r integrations/openclaw ~/.openclaw/extensions/agentmemory

Then enable it in ~/.openclaw/openclaw.json:

{
  "plugins": {
    "slots": {
      "memory": "agentmemory"
    },
    "entries": {
      "agentmemory": {
        "enabled": true,
        "config": {
          "base_url": "http://localhost:3111",
          "token_budget": 2000,
          "min_confidence": 0.5,
          "fallback_on_error": true,
          "timeout_ms": 5000
        }
      }
    }
  }
}

What the plugin does:

• claims the plugins.slots.memory = "agentmemory" slot via api.registerMemoryCapability({ promptBuilder }) so OpenClaw recognises it as the active memory plugin
• recalls relevant long-term memory before the agent starts (via the before_agent_start hook)
• captures completed conversation turns after the agent finishes (via the agent_end hook)
• shares the same backend with Claude Code, Codex CLI, Gemini CLI, Hermes, pi, and other agents

The plugin currently registers a promptBuilder only — not a full MemoryPluginRuntime adapter. OpenClaw's MemoryRuntimeBackendConfig type today is { backend: "builtin" } or { backend: "qmd" }; both are openclaw-internal backends that don't fit agentmemory's external REST shape. The hook-driven recall + capture flow above is the working integration path. If you need OpenClaw's in-process memory-runtime APIs (e.g. getMemorySearchManager) backed by agentmemory, file an upstream request against openclaw for an "external" backend type and we'll wire runtime here once the contract supports it.

Plugin validates but does not load — make sure the folder contains package.json, openclaw.plugin.json, and plugin.mjs, and that plugins.slots.memory is set to agentmemory.

plugins.slots.memory = "agentmemory" reports unavailable — upgrade to v0.9.11+. Older versions of this plugin registered hooks but never called api.registerMemoryCapability(...), so the memory-slot machinery did not consider the slot claimed. The current plugin registers a memory capability (prompt builder) at startup, which is the documented OpenClaw API for occupying the slot.

Connection refused on port 3111 — the agentmemory server is not running. Start it with npx @agentmemory/agentmemory.

No memories returned — open http://localhost:3113 and verify observations are being captured.
