Pull Request Overview

This PR fixes a bug where the streamable HTTP server was not properly releasing resources when a RequestId is removed. The key changes include modifying the logic to close the HTTP channel if its resource list is empty or if the resource is an MCP request, and adding a warning log when the channel is not found.

if let Some(channel) = self.tx_router.get_mut(&http_request_id) {
channel.resources.remove(resource);
if channel.resources.is_empty() {
// It's okey to do so, since we don't handle batch json rcp request anymore

Pull Request Overview

This PR fixes a bug where the streamable HTTP server was not properly releasing resources when a RequestId is removed. The key changes include modifying the logic to close the HTTP channel if its resource list is empty or if the resource is an MCP request, and adding a warning log when the channel is not found.

if let Some(channel) = self.tx_router.get_mut(&http_request_id) {
channel.resources.remove(resource);
if channel.resources.is_empty() {
// It's okey to do so, since we don't handle batch json rcp request anymore
