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.
mesh-sdk for Go
The skeleton (novox/hq ADR 0187): stdio.Serve(name, tools) speaks MCP over stdio to the node's
tool runtime. A Tool is a name, a description, an argument schema and a function. A tool named
<seat>.<verb> is the seat's implementation. Standard library only.
What it holds, under ADR 0039's test: the stdio loop and the tool type. Nothing else — no bus, no
client, nothing of any module's. go build ./example and pipe a tools/list request into it.
