A valid server `ping` with the same numeric ID is therefore passed to `extract_result`, which rejects it as `MCP response to 'initialize' has no result` (or `tools/list`). The ping is not answered, and initialization or tool discovery fails. The stdio transport already dispatches server requests before matching responses.
