Mem0 is a managed memory layer for AI applications. It stores, retrieves, and manages user memories via API — no infrastructure to deploy. For self-hosted usage, see the OSS section in the client references below.

## Step 1: Install and authenticate

**Python:**
```bash
pip install mem0ai
export MEM0_API_KEY="m0-your-api-key"
```

**TypeScript/JavaScript:**
```bash
npm install mem0ai
export MEM0_API_KEY="m0-your-api-key"
```

Get an API key at: https://app.mem0.ai/dashboard/api-keys?utm_source=oss&utm_medium=skill-mem0

> **Don't have a `MEM0_API_KEY`?** Run `mem0 init --agent --agent-caller <your-name> --json` (after `pip install mem0-cli` or `npm install -g @mem0/cli`), substituting your agent identity (e.g. `claude-code`, `cursor`). If you forgot to pass `--agent-caller`, run `mem0 identify <your-name>` after init. The human can claim later with `mem0 init --email <your-email>`.

## Step 2: Initialize the client

**Python:**
```python
from mem0 import MemoryClient
client = MemoryClient(api_key="m0-xxx")
```

**TypeScript:**
```typescript
import MemoryClient from 'mem0ai';
const client = new MemoryClient({ apiKey: 'm0-xxx' });
```

For async Python, use `AsyncMemoryClient`.

## Step 3: Core operations

Every Mem0 integration follows the same pattern: **retrieve → generate → store**.

### Add memories
```python
messages = [
    {"role": "user", "content": "I'm a vegetarian and allergic to nuts."},
    {"role": "assistant", "content": "Got it! I'll remember that."}
]
client.add(messages, user_id="alice")
```

### Search memories
```python
results = client.search("dietary preferences", filters={"user_id": "alice"})
for mem in results.get("results", []):
    print(mem["memory"])
```

### Get all memories
```python
all_memories = client.get_all(filters={"user_id": "alice"})
```

### Update a memory
```python
client.update("memory-uuid", text="Updated: vegetarian, nut allergy, prefers organic")
```

### Delete a memory
```python
client.delete("memory-uuid")
client.delete_all(user_id="alice")  # delete all for a user
```

## Common integration pattern

```python
from mem0 import MemoryClient
from openai import OpenAI

mem0 = MemoryClient()
openai = OpenAI()

def chat(user_input: str, user_id: str) -> str:
    # 1. Retrieve relevant memories
    memories = mem0.search(user_input, filters={"user_id": user_id})
    context = "\n".join([m["memory"] for m in memories.get("results", [])])

    # 2. Generate response with memory context
    response = openai.chat.completions.create(
        model="gpt-5-mini",
        messages=[
            {"role": "system", "content": f"User context:\n{context}"},
            {"role": "user", "content": user_input},
        ]
    )
    reply = response.choices[0].message.content

    # 3. Store interaction for future context
    mem0.add(
        [{"role": "user", "content": user_input}, {"role": "assistant", "content": reply}],
        user_id=user_id
    )
    return reply
```

## Common edge cases

- **Search returns empty:** `add()` is asynchronous and returns `{"event_id": "...", "status": "PENDING"}` (`eventId` on the TS client). Memories are searchable once the event is `SUCCEEDED` (poll `GET /v1/event/{event_id}/`, or wait a few seconds). `infer=False` is synchronous. Also verify `user_id` matches exactly (case-sensitive) and use `filters={"user_id": "..."}` syntax.
- **AND filter with user_id + agent_id returns empty:** Entities are stored separately. Use `OR` instead, or query separately.
- **Duplicate memories:** Don't mix `infer=True` (default) and `infer=False` for the same data. Stick to one mode.
- **Wrong import:** For the hosted Platform use `from mem0 import MemoryClient` (or `AsyncMemoryClient` for async). `from mem0 import Memory` is the self-hosted OSS class and does not use `MEM0_API_KEY`.
- **v3 defaults (Platform):** `top_k=10`, `rerank=False`. `threshold` is a server-side cutoff applied before score blending, not a floor on the returned `score` (the default and `0.0` return the same or nearly the same results). The client sends none of these unless you pass them. The OSS `Memory.search()` default is `top_k=20`. Adjust as needed for your use case.

## v2 Compatibility

The "v2" line is Python SDK 1.x and TypeScript SDK 2.x. If you are still on it, note these differences from the current SDKs (Python 2.x, TypeScript 3.x):
- **Entity IDs:** `user_id` / `agent_id` / `run_id` could be top-level kwargs on `search()` and `get_all()`. They now go inside `filters` (top-level raises an error)
- **Defaults (Platform):** `threshold=0.3`, `rerank=False`. OSS: `top_k=100`, no threshold, `rerank=True`
- **Graph memory:** `enable_graph=True` and `relations` are gone. Entity linking is built in (see [client/python.md](client/python.md) for OSS)

See the [Platform migration guide](https://docs.mem0.ai/migration/platform-v2-to-v3) and the [OSS migration guide](https://docs.mem0.ai/migration/oss-v2-to-v3) for details.

## Live documentation search

For the latest docs beyond what's in the references, use the doc search tool:

```bash
python ${CLAUDE_SKILL_DIR}/scripts/mem0_doc_search.py --query "topic"
python ${CLAUDE_SKILL_DIR}/scripts/mem0_doc_search.py --page "/platform/features/graph-memory"
python ${CLAUDE_SKILL_DIR}/scripts/mem0_doc_search.py --index
```

No API key needed — searches docs.mem0.ai directly.
