5 steps from nothing to working: SSH key + config → enable
external MCP → register mother server → install hw-probe →
restart daemon. Uses real hosts (osa.smilepowered.org at
100.72.229.63, USB as clawdie-usb) with l33t placeholder keys.
ASCII architecture diagram showing persistent SSH child process,
JSON-RPC over stdin/stdout, mother-side forced-command wrapper.
Includes: end-to-end test, future autospawn flow, and
troubleshooting table for all common failure modes.
USB can connect to mother right now with 0.11 daemon —
colibri_external_mcp_call_tool is already in the tools list.
Just needs: SSH key, external-mcp.json, COLIBRI_MCP_EXTERNAL_CALL=1,
hw-probe installed, and daemon restart.
Architecture: USB spawns 'ssh colibri@mother colibri-mcp' as
persistent child process, JSON-RPC over stdin/stdout. Mother-side
wrapper strips forced-command layer. One SSH connection for
daemon lifetime.
Missing: node_register MCP tool on mother (needs implementation),
auto-key from seed partition (planned for 0.12 ISO build).
