# `fastmcp.server.middleware.middleware`
|
|
|
|
## Functions
|
|
|
|
### `make_middleware_wrapper` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/server/middleware/middleware.py#L106"><Icon icon="github" size="14" /></a></sup>
|
|
|
|
```python
|
|
make_middleware_wrapper(middleware: Middleware, call_next: CallNext[T, R]) -> CallNext[T, R]
|
|
```
|
|
|
|
|
|
Create a wrapper that applies a single middleware to a context. The
|
|
closure bakes in the middleware and call_next function, so it can be
|
|
passed to other functions that expect a call_next function.
