# Tool API

### Structure of Tool Query and Response

The `ToolQuery` class defines the structure for tool operation requests:

```python
class ToolQuery(Query):
    query_class: str = "tool"
    tool_calls: List[Dict[str, Union[str, Any]]]
    
    class Config:
        arbitrary_types_allowed = True
```

The `ToolResponse` class defines the structure for tool operation responses:

```python
class ToolResponse(Response):
    response_class: str = "tool"
    response_message: Optional[str] = None
    finished: bool = False
    error: Optional[str] = None
    status_code: int = 200
```

### Available Tool Management Commands

# View all tools available in the AIOS Tool Hub
list-toolhub-tools
```

  --tool_name <tool_name> \
  --tool_version <version_number> \
  --toolhub_url <hub_url>
```

**Upload a Tool**
