## Functions

### `get_http_headers` <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/fastmcp_slim/fastmcp/client/dependencies.py#L19" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python theme={"theme":{"light":"snazzy-light","dark":"dark-plus"}}
get_http_headers(include_all: bool = False, include: set[str] | None = None) -> dict[str, str]
```

Return HTTP headers from an ambient server request, when available.

The standalone client package has no server request context. When the full
FastMCP package is installed, delegate to its request-aware implementation.
