NemoClaw/OpenClaw Plugin

The Walrus Memory plugin adds portable, verifiable agent memory to OpenClaw agents. It works alongside OpenClaw's existing file-based memory, automatically recalling relevant context and capturing new facts in the background, with no user action needed. Memory is not locked to a single runtime: it operates across agents, apps, and workflows.

Features​

Automatic Recall

Relevant memories are injected into the LLM's context before each conversation turn

Automatic Capture

Facts are extracted from conversations and stored as encrypted memories after each turn

Fully Under Your Control

Seal-encrypted, stored on Walrus, programmable permissions and explicit ownership over your data

Portable Across Apps

Memories stored from any Walrus Memory-connected app are accessible to your OpenClaw agent, not locked to a single provider

Multi-Agent Isolation

Each agent gets its own memory space through namespaces, no cross-contamination

Prompt Injection Protection

Detection and HTML escaping on both read and write paths

Agent Tools

Optional memory_search and memory_store tools for explicit LLM control

CLI Commands

openclaw memwal search and openclaw memwal stats for debugging and inspection

When to use this​

  • You want your OpenClaw agents to remember across conversations, preferences, decisions, context
  • You need encrypted, user-owned memory instead of plaintext files or platform-managed storage
  • You want cross-app continuity, memories from other Walrus Memory-connected apps (chatbot, noter, researcher) surface in OpenClaw
  • You're running multiple agents and need each to have its own isolated memory space
