Adding Persistent Memory to OpenClaw with Mem0
Browse more in Tools & plugins.
All tools & plugins guides →This guide shows you how to add persistent memory to OpenClaw using the Mem0 community plugin pattern. You will install a plugin with the OpenClaw CLI, wire it into your agent stack, and understand how community plugins fit into ClawHub and npm.
By the end, you will have OpenClaw extended with a persistent-memory plugin installed via the standard `openclaw plugins install` flow.
Prerequisites
- ✓An existing OpenClaw deployment with the `openclaw` CLI available in your shell.
- ✓Network access from your OpenClaw environment to ClawHub and npm so `openclaw plugins install <package-name>` can resolve packages.
- ✓A GitHub account if you plan to host or inspect the Mem0 plugin source in a public repository.
Steps
- 1
Understand how OpenClaw installs community plugins
Before you add Mem0, you need to understand how OpenClaw discovers and installs community plugins. OpenClaw treats Mem0 like any other plugin: it looks it up on ClawHub first and falls back to npm, using a single CLI command.
This is the mechanism you rely on to bring Mem0 into your agent runtime.

Install the Mem0 persistent memory plugin with the OpenClaw CLI
Install the Mem0 plugin using the same community plugin command pattern so OpenClaw can load it as part of your agent. The CLI checks ClawHub first, then npm, which means you do not manage raw npm commands or git clones yourself.
Run the install from the environment where your OpenClaw gateway or agents execute so the plugin is available at runtime.

Verify the Mem0 plugin is published on ClawHub or npm
Mem0 must be published on ClawHub or npm so `openclaw plugins install` works reliably. This matches the quality bar OpenClaw enforces for community plugins and ensures your persistent memory plugin is discoverable and installable in production.
If you maintain a fork or variant of Mem0, publish it to one of these registries before wiring it into your stack.

Host or inspect the Mem0 plugin source on GitHub
Community plugins, including a Mem0 persistent memory plugin, should live in a public GitHub repository with setup docs and an issue tracker. This lets you audit how the plugin stores and retrieves memories and track bugs or feature requests.
When you evaluate Mem0 for production, review its repo for maintenance activity and configuration guidance.

Align Mem0 with OpenClaw’s community plugin quality bar
When you depend on Mem0 for persistent memory, you want it to meet the same quality bar as other OpenClaw plugins. The docs call out requirements like being published on ClawHub or npm, having setup and usage docs, and showing active maintenance.
Use this checklist when you choose a Mem0 package or decide whether to upgrade it in your environment.
Troubleshooting
`openclaw plugins install <package-name>` fails because the Mem0 package cannot be found
This happens when the Mem0 plugin is not published on ClawHub or npm under the name you are using. Confirm that the package is actually published to ClawHub (preferred) or npm and that the name you pass to `openclaw plugins install <package-name>` matches the published package name exactly.

OpenClaw expects community plugins to ship with setup and usage docs and to be actively maintained. If Mem0 loads but does not behave as expected, check its public GitHub repository for configuration instructions and recent updates, and verify you installed it in the same environment where your OpenClaw gateway or agents run.
