TOCK_WS_PORT — Concentrator port for the fetchproxy browser bridge (defaults to the fleet-shared 37149). On one machine every MCP shares the concentrator, so move it for ALL of them or not at all.
FETCHPROXY_WS_HOST — Bind interface, a literal IP only (anything else is ignored); default 127.0.0.1. Keep on loopback — it exists for ONE topology: a hosted child in its own network namespace.
FETCHPROXY_IDENTITY_DIR — Where to store the long-term identity keypair, an absolute path only (anything else is ignored); default ~/.fetchproxy/identity/. Exists for a host that runs a separate child per caller.
