# `fastmcp.server.providers.transforming`
TransformingProvider for applying component transformations.
This module provides the `TransformingProvider` class that wraps any Provider
and applies transformations like namespace prefixes and tool renames.
## Classes
### `TransformingProvider`
Wraps any provider and applies component transformations.
Users typically use `provider.with_transforms()` rather than instantiating
this class directly. Multiple `.with_transforms()` calls stack - each
creates a new wrapper that composes with the previous.
**Methods:**
#### `list_tools`
```python
list_tools(self) -> Sequence[Tool]
```
List tools with transformations applied.
#### `get_tool`
```python
get_tool(self, name: str) -> Tool | None
```
Get tool by transformed name.
#### `list_resources`
```python
list_resources(self) -> Sequence[Resource]
```
List resources with URI transformations applied.
#### `get_resource`
```python
get_resource(self, uri: str) -> Resource | None
```
Get resource by transformed URI.
#### `list_resource_templates`
```python
list_resource_templates(self) -> Sequence[ResourceTemplate]
```
List resource templates with URI transformations applied.
#### `get_resource_template`
```python
get_resource_template(self, uri: str) -> ResourceTemplate | None
```
Get resource template by transformed URI.
#### `list_prompts`
```python
list_prompts(self) -> Sequence[Prompt]
```
List prompts with transformations applied.
#### `get_prompt`
```python
get_prompt(self, name: str) -> Prompt | None
```
Get prompt by transformed name.
#### `get_tasks`
```python
get_tasks(self) -> Sequence[FastMCPComponent]
```
Get tasks with transformations applied to all components.
#### `lifespan`
```python
lifespan(self) -> AsyncIterator[None]
```
Delegate lifespan to wrapped provider.
