Class AsyncMcpResourceListChangedProvider

java.lang.Object
org.springframework.ai.mcp.annotation.provider.changed.resource.AsyncMcpResourceListChangedProvider
public class AsyncMcpResourceListChangedProvider extends Object
Provider for asynchronous resource list changed consumer callbacks.

This class scans a list of objects for methods annotated with McpResourceListChanged and creates Function callbacks for them. These callbacks can be used to handle resource list change notifications from MCP servers in a reactive way.

Example usage: 

// Create a provider with a list of objects containing @McpResourceListChanged methods
AsyncMcpResourceListChangedProvider provider = new AsyncMcpResourceListChangedProvider(List.of(resourceListHandler));

// Get the list of resource list changed consumer callbacks
List<AsyncResourceListChangedSpecification> specifications = provider.getResourceListChangedSpecifications();

// Add the consumers to the client features
McpClientFeatures.Async clientFeatures = new McpClientFeatures.Async(
    clientInfo, clientCapabilities, roots,
    toolsChangeConsumers, resourcesChangeConsumers, promptsChangeConsumers,
    loggingConsumers, samplingHandler);
