Parameters

Name	Type	Description
`connections`	`dict[str, Connection] \| None`	Default:`None` A `dict` mapping server names to connection configurations. If `None`, no initial connections are established.
`callbacks`	`Callbacks \| None`	Default:`None` Optional callbacks for handling notifications and events.
`tool_interceptors`	`list[ToolCallInterceptor] \| None`	Default:`None` Optional list of tool call interceptors for modifying requests and responses.
`tool_name_prefix`	`bool`	Default:`False` If `True`, tool names are prefixed with the server name using an underscore separator (e.g., `"weather_search"` instead of `"search"`). This helps avoid conflicts when multiple servers have tools with the same name. Defaults to `False`.
