The node's runtime launches a tools bundle as a process and speaks MCP over stdio to it, so a tool may be written in any language and the transport stays in the runtime (ADR 0039's refusal, kept). Each SDK is the loop and the tool type and nothing else: `@novox/mesh-sdk/stdio` (serveStdio, and serveRegisteredOverStdio for a bundle that already registers the in-process way), python/, go/, rust/ and c/ beside it, each with an example answering `greet` and the seat verb `node-lamp.on`. Skeletons, by the operator's direction: the bare minimum one bundle per language needs to be built and answer, proven here by each example answering tools/list and tools/call on stdio.
