Class McpRootsListChangedFilter

java.lang.Object
com.xebialabs.xlrelease.mcp.config.McpRootsListChangedFilter
All Implemented Interfaces:
jakarta.servlet.Filter
public class McpRootsListChangedFilter extends Object implements jakarta.servlet.Filter
Acknowledges and discards notifications/roots/list_changed before it reaches the MCP servlet.

The SDK's handler for that notification (McpAsyncServer#asyncRootsListChangedNotificationHandler) calls exchange.listRoots() unconditionally — it substitutes a logging consumer when no roots consumers are registered, as is the case here, so the round-trip to the client goes out regardless. The servlet transport handles notifications by blocking the request thread on that result, so a client that announces roots but never answers the roots/list request pins a worker thread for the full request timeout and then logs a TimeoutException. Claude Desktop (through mcp-remote) does exactly that.

Nothing in Release consumes roots, so the notification is answered with 202 and dropped here.
