feat(integrations): add n8n community node for Mem0

A programmatic n8n community node wrapping the hosted Mem0 v3 REST API: add, search, get, get-many, update, delete, plus usableAsTool so the n8n AI Agent can call it. - Zero runtime dependencies (calls REST directly), TypeScript, ESLint clean — meets n8n verified-node requirements - Add supports custom_instructions, custom_categories, includes, excludes, a client-side entity-id guard, and async event polling (itemIndex on errors) - Anonymous opt-out telemetry (MEM0_TELEMETRY=false) - Docs page + docs.json/llms.txt entry, ci-gate + release wiring, AGENTS.md rows - Verified: tsc + ESLint + live E2E (add → search → get → delete) vs api.mem0.ai Split out of #6057 per review (separate PRs per integration).

+title: n8n
+description: "Add long-term memory to n8n workflows and AI Agents with the Mem0 community node, no code required."
+---
+
+The [`n8n-nodes-mem0`](https://www.npmjs.com/package/n8n-nodes-mem0) community node brings [Mem0](https://mem0.ai) memory to [n8n](https://n8n.io). Add, search, and manage long-term memories inside any workflow, and use it as a tool for the n8n AI Agent.
+
+## Overview
+
+The node wraps the hosted Mem0 REST API and supports six operations on the **Memory** resource:
+
+| Operation | Endpoint |
+| --- | --- |
+| **Add** | `POST /v3/memories/add/` |
+| **Search** | `POST /v3/memories/search/` |
+| **Get** | `GET /v1/memories/{id}/` |
+| **Get Many** | `POST /v3/memories/` |
+| **Update** | `PUT /v1/memories/{id}/` |
+| **Delete** | `DELETE /v1/memories/{id}/` |
+
+It is marked `usableAsTool`, so the n8n AI Agent (Tools Agent) can call it directly to remember and recall information.
+
+## Installation
+
+Install it like any n8n community node:
+
+1. In n8n, go to **Settings → Community Nodes → Install**.
+2. Enter `n8n-nodes-mem0` and confirm.
+
+The node then appears in the nodes panel under the AI category.
+
+## Authentication
+
+Create a **Mem0 API** credential in n8n:
+
+- **API Key**: from the <a href="https://app.mem0.ai/dashboard/api-keys?utm_source=oss&utm_medium=integration-n8n" rel="nofollow">Mem0 API Key dashboard</a>. Sent as `Authorization: Token <key>`.
+- **Base URL**: defaults to `https://api.mem0.ai`.
+
+## Operations
+
+### Add
+
+Extracts and stores memories from one or more messages. Provide at least one entity id (**User ID**, **Agent ID**, **Run ID**, or **App ID** in Additional Fields); the node validates this before calling the API. Additional Fields also expose **Metadata (JSON)** and **Infer** (run LLM extraction, or store verbatim).
+
+Extraction is asynchronous. **Wait for Completion** (on by default) polls the event until it finishes and returns the resulting memories; turn it off to return immediately with the event ID.
+
+### Search
+
+Semantic search over stored memories. Provide a **Query**, a **User ID** (required, the API needs an entity filter), and an optional **Limit**.
+
+### Get Many
+
+Lists memories for a **User ID** with **Page** and **Page Size** controls.
+
+### Get / Update / Delete
+
+Operate on a single memory by **Memory ID**. Update accepts new **Text** and/or **Metadata (JSON)**.
+
+## Choosing a `userId`
+
+The `userId` is a stable string you choose to identify whose memories these are. It is not looked up in the dashboard. Common choices are your app's internal user ID, an email, or a UUID. Use the same value across Add, Search, and Get Many so recall works.

+# 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](#installation) · [Operations](#operations) · [Credentials](#credentials) · [Usage](#usage) · [Resources](#resources)
+
+## 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.
