第 4 层 Dispatcher 经 NATS request-reply + 队列组同步调用第 5 层 MCP 工具， 工具不可用/超时即降级，不阻断主流程。 - shared/contract: ToolCall/ToolResult + sundynix.tools.go.* subject 约定 + ToolSubjectGo/Py - shared/bus: CallTool(发起) / ServeTool(队列组订阅+应答) - mcp-go: 接共享 bus，gateway 通配订阅按工具名分发(wiki_search/echo)，main 优雅退出 - dispatcher: ToolCaller 接口 + Orchestrator.retrieveContext(调 wiki_search,超时3s降级) - e2e: TestToolCallRoundTrip(PASS)；demo.sh 加 mcp-go(就绪门避免启动竞态)，live 跑通 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
