defaultToolCallbacks(ToolCallbackProvider) wires two real stdio MCP servers (the official filesystem server and git server) into ChatClient, contrasted with defaultTools(Object) for a local @Tool method. Every call -- MCP-sourced or local -- is logged through one Micrometer ObservationHandler<ToolCallingObservationContext>; a first version wired that handler two ways at once and every call logged twice, which is now a regression test. No real LLM is used anywhere: every test builds an AssistantMessage.ToolCall by hand and drives it through the real ToolCallingManager bean against real npx/uvx-launched MCP server processes.
