- **Weaviate gRPC**: `localhost:50055`
- **Chainlit UI**: `localhost:8000`

## Server Paths
- **RAG System**: `/opt/cloodle/tools/ai/multi_agent_rag_system/`
- **Chatbot**: `/opt/cloodle/tools/ai/moodle-chatbot/`

## Weaviate Client Configuration
```python
import weaviate

client = weaviate.Client(
    url="http://localhost:8095",

schema = {
    "class": "MoodleDocument",
    "vectorizer": "text2vec-transformers",
    "properties": [
        {"name": "content", "dataType": ["text"]},
        {"name": "source", "dataType": ["string"]},
        {"name": "course_id", "dataType": ["int"]}
    ]
}
client.schema.create_class(schema)
```
