Programmatic n8n node (n8n-nodes-mem0) with Add/Search/Get Many/Get/
Update/Delete memory operations against the Mem0 v3 API, plus API-key
credentials and usableAsTool support for the AI Agent node.
Add uses POST /v3/memories/add/ and polls GET /v1/event/{id}/ until the
async extraction resolves. No runtime dependencies (n8n verification
requirement); calls the REST API directly. MIT licensed per-package.

# n8n-nodes-mem0
|
|
|
|
This is an n8n community node that lets you use [Mem0](https://mem0.ai) — the memory layer for AI agents — in your n8n workflows.
|
|
|
|
Mem0 gives your agents long-term memory: add memories from conversations, then search and recall them across sessions.
|
|
|
|
[n8n](https://n8n.io) is a [fair-code licensed](https://docs.n8n.io/reference/license/) workflow automation platform.

|
## Installation
|
|
|
|
Follow the [community nodes installation guide](https://docs.n8n.io/integrations/community-nodes/installation/) and install `n8n-nodes-mem0`.
|
|
|
|
## Operations
|
|
|
|
The **Memory** resource supports:
|
|
|
|
| Operation | Description | Endpoint |
|
|
| --- | --- | --- |
|
|
| **Add** | Extract and store memories from messages | `POST /v3/memories/add/` |
|
|
| **Search** | Semantic search over stored memories | `POST /v3/memories/search/` |
|
|
| **Get Many** | List memories for a user (paginated) | `POST /v3/memories/` |
|
|
| **Get** | Retrieve a single memory by ID | `GET /v1/memories/{id}/` |
|
|
| **Update** | Update a memory's text or metadata | `PUT /v1/memories/{id}/` |
|
|
| **Delete** | Delete a single memory by ID | `DELETE /v1/memories/{id}/` |
|
|
|
|
### Add & asynchronous extraction
|
|
|
|
By default, **Add** runs LLM-based extraction asynchronously — the API returns an event ID and the node polls until extraction finishes, then returns the resulting memories. Disable **Wait for Completion** to return immediately with the event ID, or set **Infer = false** (under Additional Fields) to store messages verbatim and return synchronously.
|
|
|
|
## Credentials
|
|
|
|
You need a Mem0 API key. Create one at [app.mem0.ai](https://app.mem0.ai) → Settings → API Keys. The key is sent as `Authorization: Token <key>`.
|
|
|
|
## Usage
|
|
|
|
This node is also **usable as a tool** by n8n's AI Agent node — attach it so an agent can "remember" and "recall" autonomously.
|
|
|
|
A typical loop:
|
|
|
|
1. **Search** memory before answering, filtered by `User ID`.
|
|
2. **Add** durable facts after a meaningful exchange.
|
|
|
|
Memory writes are asynchronous by default; allow a moment after an Add before searching for the same content.
