title: "BashServerToolEngine"
---

Which bash engine to use. "openrouter" runs commands server-side in the OpenRouter sandbox. "auto" (default) and "native" use native passthrough, returning the tool call to your application to run client-side; OpenRouter does not execute the commands.

## Example Usage

```python
from openrouter.components import BashServerToolEngine

# Open enum: unrecognized values are captured as UnrecognizedStr
value: BashServerToolEngine = "auto"
```


## Values

This is an open enum. Unrecognized values will not fail type checks.

- `"auto"`
- `"native"`
- `"openrouter"`
