# mem0 Memory Adapter

Hosted `recall`/`save` adapter backed by a mem0 server. mem0 owns extraction and ranking

server-side. Talks to the server over plain HTTP — **no SDK peer dependency**.

## Setup

```ts

import { memoryMiddleware } from '@tanstack/ai-memory'

import { mem0 } from '@tanstack/ai-memory/mem0'

const memory = mem0({ user: currentUserId }) // baseUrl defaults to MEM0_URL

memoryMiddleware({ adapter: memory, scope })

```

Requires a running mem0 server (self-hosted or hosted). Point it via `baseUrl` (or

`MEM0_URL`); pass `apiKey` (or `MEM0_ADMIN_API_KEY`) when secured.

## Options

- `user` — mem0 `user_id` (falls back to `scope.userId`, then `'demo-user'`).

- `baseUrl` — mem0 server URL (default `MEM0_URL` or `http://localhost:8000`).

- `apiKey` — bearer token (default `MEM0_ADMIN_API_KEY`).

- `rerank` (default `true`), `threshold` (default `0.1`) — search tuning.

+ **Scope fields:** requests send `user_id` and `run_id` (`scope.threadId`). `tenantId`

+ and `namespace` are not sent — encode multi-tenant isolation into `user` if needed.

`save` posts the `{ user, assistant }` turn to `/memories`; `recall` queries `/search`

and renders the results into the system prompt. mem0 exposes no LLM tools.
