# fastmcp.server.middleware.timing

Timing middleware for measuring and logging request performance.

## Classes

### TimingMiddleware

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`

```python
on_request(self, context: MiddlewareContext, call_next: CallNext) -> Any
```

Time request execution and log the results.

### DetailedTimingMiddleware

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.

**Methods:**

#### `on_call_tool`

```python
on_call_tool(self, context: MiddlewareContext, call_next: CallNext) -> Any
```

Time tool execution.

#### `on_read_resource`

```python
on_read_resource(self, context: MiddlewareContext, call_next: CallNext) -> Any
```

Time resource reading.

#### `on_get_prompt`

```python
on_get_prompt(self, context: MiddlewareContext, call_next: CallNext) -> Any
```

Time prompt retrieval.

#### `on_list_tools`

```python
on_list_tools(self, context: MiddlewareContext, call_next: CallNext) -> Any
```

Time tool listing.

#### `on_list_resources`

```python
on_list_resources(self, context: MiddlewareContext, call_next: CallNext) -> Any
```

Time resource listing.

#### `on_list_resource_templates`

```python
on_list_resource_templates(self, context: MiddlewareContext, call_next: CallNext) -> Any
```

Time resource template listing.

#### `on_list_prompts`

```python
on_list_prompts(self, context: MiddlewareContext, call_next: CallNext) -> Any
```

Time prompt listing.
