# `fastmcp.server.providers.aggregate`
|
|
|
|
|
|
AggregateProvider for combining multiple providers into one.
|
|
|
|
This module provides `AggregateProvider` which presents multiple providers
|
|
as a single unified provider. Used internally by FastMCP for aggregating
|
|
components from all providers.
|
|
|
|
|
|
## Classes
|
|
|
|
### `AggregateProvider` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/server/providers/aggregate.py#L30" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>
|
|
|
|
|
|
Presents multiple providers as a single provider.
|
|
|
|
Components are aggregated from all providers. For get_* operations,
|
|
providers are queried in parallel and the highest version is returned.
|
|
|
|
Errors from individual providers are logged and skipped (graceful degradation).
|
|
|
