# Copy Context To Callable • AI Agent SDK
> copy_context_to_callable: Wrap a callable to copy the current context to the new thread/executor.
# copy\_context\_to\_callable
Function
> This function is defined in the [**context\_events**](../modules/context_events) module.
Wrap a callable to copy the current context to the new thread/executor.
This is needed because contextvars are NOT automatically propagated to
thread pool executors. Use this when calling run\_in\_executor().
## Signature
```python theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
def copy_context_to_callable(func: Any) -> Any
```
## Parameters
The callable to wrap.
### Returns
A wrapped callable that copies the current context.
## Usage
```python theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
# Instead of:
await loop.run_in_executor(None, lambda: agent.chat(prompt))
# Use:
await loop.run_in_executor(None, copy_context_to_callable(lambda: agent.chat(prompt)))
```
## Uses
* `contextvars.copy_context`
* `ctx.run`
## Used By
