+# mesh-console
+
+The mesh's tools, on the machine a person sits at, served by a module the mesh assigned there
+(novox/hq [ADR 0152](https://git.novox.be/novox/hq), design 34).
+
+Assign it to a machine and an agent on that machine has the mesh's tools at
+`http://127.0.0.1:<port>/mcp` — MCP over HTTP, `initialize`, `tools/list`, `tools/call`. A person at
+a terminal reaches the same endpoint with `mesh tools --console http://127.0.0.1:<port>` and
+`mesh call <module>.<tool> --console …`, with no credential of their own: the console holds it.
+
+## What it is
+
+The tool runtime's own client, `mesh serve`, started by the mesh on the credential it sealed to the
+machine for `<node>.mesh-console`. The manifest says three things nothing else in the catalogue says
+together:
+
+- `invokes: ["*"]` — it calls every tool on the mesh, and the bus grants exactly that publish side;
+- a listener `from: machine` — loopback only, and the filter opens nothing for it;
+- no `emits`, no `consumes`, no `tools` — nothing on the bus can address it.
+
+**Loopback is the authority boundary.** Whoever can connect is on the machine, and whoever is on the
+machine is the account that owns the mesh there (ADR 0034, ADR 0144). There is no token and no login,
+and `mesh serve` refuses to bind anything but a loopback address.
+
+## What it lists
+
+What the running modules answer: every tool runtime serves a `tools` verb for its module, and the
+console asks the catalogue which modules the mesh holds and each module what it serves. A module that
+did not answer — not assigned, not up, or built before the runtime answered `tools` — is named in the
+list's `_meta.notAnswering` and can still be called by `<module>.<tool>`.
+
+The mesh's own verbs (`status`, `push`, `assign`) are the `mesh-controller` seat's tools under
+ADR 0132 and are not served on the bus yet; they appear here when they are.
+
+## Port
+
+The manifest declares port 4270 and the mesh assigns the machine port as it does for any listener;
+the console binds `127.0.0.1:${port:4270}`. `node show <machine>` says which port a machine was given.
