## Before you call it

1. Use remember, recall and forget. The older cognify, search and delete MCP tools are gone
2. Always include /api/v1 in REST paths
3. Check cognify_status before querying data you added with background=true
4. Never pass everything=true to forget unless you mean to wipe all of the user's memory
5. Set a client timeout on Cloud calls and treat HTTP 402 as an empty balance, since an empty balance has also shown up as hangs

## Connect

```bash
pip install cognee
```

```bash
# COGNEE_URL is your tenant host, e.g. https://<tenant>.aws.cognee.ai
curl -X POST "$COGNEE_URL/api/v1/search" -H "X-Api-Key: $COGNEE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query":"What does the user prefer?"}'
```

```bash
docker run -d -e TRANSPORT_MODE=http -e LLM_API_KEY=$LLM_API_KEY -p 8000:8000 cognee/cognee-mcp:main
claude mcp add --transport http cognee http://localhost:8000/mcp
```
