# `fastmcp.server.middleware.timing`
|
|
|
|
|
|
Timing middleware for measuring and logging request performance.
|
|
|
|
## Classes
|
|
|
|
### `TimingMiddleware` <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/src/fastmcp/server/middleware/timing.py#L10" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>
|
|
|
|
|
|
Middleware that logs the execution time of requests.
|
|
|
|
Only measures and logs timing for request messages (not notifications).
|
|
Provides insights into performance characteristics of your MCP server.
|
|
|
|
|
|
**Methods:**
|
|
|
|
#### `on_request` <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/src/fastmcp/server/middleware/timing.py#L39" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>
|
|
|
|
```python
|
|
on_request(self, context: MiddlewareContext, call_next: CallNext) -> Any
|
|
```
|
|
|
|
Time request execution and log the results.
|
|
|
|
|
|
### `DetailedTimingMiddleware` <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/src/fastmcp/server/middleware/timing.py#L60" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>
|
|
|
|
|
|
Enhanced timing middleware with per-operation breakdowns.
|
|
|
|
Provides detailed timing information for different types of MCP operations,
|
|
allowing you to identify performance bottlenecks in specific operations.
