# ServerToolExecutedBy

Who runs the tool call: the model provider during inference (`provider`), OpenRouter (`openrouter`), or the caller's application after the call is returned (`client`).

## Example Usage

```python theme={null}
from openrouter.components import ServerToolExecutedBy

# Open enum: unrecognized values are captured as UnrecognizedStr
value: ServerToolExecutedBy = "provider"
```

## Values

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

* `"provider"`
* `"openrouter"`
* `"client"`
