# mesh-sdk for Go `stdio.Serve("", tools)` speaks MCP over stdio to the node's tool runtime, as the module the runtime names (novox/hq ADR 0188, ADR 0193). A `Tool` is a name, a description, an argument schema and a function; calls run concurrently. A tool named `.` is the seat's implementation. `stdio.Emit(type, body)` publishes an event as the module, `stdio.Subscribe(pattern, handler)` receives the module's events (taken when the handler returns nil, offered again when it returns an error — the one rule is in the repository README, "Taking an event") and `stdio.Ask(key, body)` calls a tool, and `stdio.State(name)` gets, puts, deletes, lists and watches the module's declared state — all through the runtime (novox/hq ADR 0193, 0198, 0201). Standard library only. ## Installing ``` GOPRIVATE=git.novox.be go get git.novox.be/novox/mesh-sdk/go@latest ``` Releases are tagged `go/vX.Y.Z` in this repository, the subdirectory form Go's module system expects, at the same version as the TypeScript package. What it holds, under ADR 0039's test: the stdio loop and the tool type, and `cli`, the local protocol `mesh-cli` speaks to the node-engine on its machine (novox/hq ADR 0272): the socket's path and one request and one answer. Nothing else — no bus, no client, nothing of any module's. `go build ./example` and pipe a `tools/list` request into it.
