# `fastmcp.server.providers.openapi.provider`
OpenAPIProvider for creating MCP components from OpenAPI specifications.
## Classes
### `OpenAPIProvider` <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/src/fastmcp/server/providers/openapi/provider.py#L51" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>
Provider that creates MCP components from an OpenAPI specification.
Components are created eagerly during initialization by parsing the OpenAPI
spec. Each component makes HTTP calls to the described API endpoints.
**Methods:**
#### `lifespan` <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/src/fastmcp/server/providers/openapi/provider.py#L181" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>
```python
lifespan(self) -> AsyncIterator[None]
```
Manage the lifecycle of the auto-created httpx client.
#### `get_tasks` <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/src/fastmcp/server/providers/openapi/provider.py#L431" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>
```python
get_tasks(self) -> Sequence[FastMCPComponent]
```
Return empty list - OpenAPI components don't support tasks.
