Manages observability callbacks for MCP agents.
This class provides a centralized way to collect and manage callbacks
from various observability platforms (Langfuse, Laminar, etc.).
```python theme={null}
from mcp_use.agents.observability.callbacks_manager import ObservabilityManager
```
### `method` **init**
Initialize the ObservabilityManager.
**Parameters**
> Optional list of custom callbacks to use instead of defaults.
**Signature**
```python wrap theme={null}
def __init__(custom_callbacks: list | None = None):
```
### `method` add\_callback
Add a callback to the custom callbacks list.
**Parameters**
> The callback to add.
**Signature**
```python wrap theme={null}
def add_callback(callback):
```
### `method` clear\_callbacks
Clear all custom callbacks.
**Signature**
```python wrap theme={null}
def clear_callbacks():
```
### `method` get\_callbacks
Get the list of callbacks to use.
**Returns**
> List of callbacks - either custom callbacks if provided, or all available observability handlers.
**Signature**
```python wrap theme={null}
def get_callbacks():
```
### `method` get\_handler\_names
Get the names of available handlers.
**Returns**
> List of handler names (e.g., \["Langfuse", "Laminar"])
**Signature**
```python wrap theme={null}
def get_handler_names():
```
### `method` has\_callbacks
Check if any callbacks are available.
**Returns**
> True if callbacks are available, False otherwise.
**Signature**
```python wrap theme={null}
def has_callbacks():
```
## create\_manager
### `function` create\_manager
Create a new ObservabilityManager instance.
```python theme={null}
from mcp_use.agents.observability.callbacks_manager import create_manager
```
**Parameters**
> Optional list of custom callbacks.
**Returns**
> A new ObservabilityManager instance.
**Signature**
```python wrap theme={null}
def create_manager(custom_callbacks: list | None = None):
```
## get\_default\_manager
### `function` get\_default\_manager
Get the default ObservabilityManager instance.
```python theme={null}
from mcp_use.agents.observability.callbacks_manager import get_default_manager
```
**Returns**
> The default ObservabilityManager instance (singleton).
**Signature**
```python wrap theme={null}
def get_default_manager():
```
