# mesh-sdk for Rust

The skeleton (novox/hq ADR 0188): `mesh_sdk::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. One dependency, `serde_json`.

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. `cargo build --example greet` and pipe a `tools/list` request in.
