It sees your bench.

Double-tap, say what you're stuck on. The eye grounds every answer in what's actually in front of you.

It turns to look.

Say "look at this" and the eye centers it. Motorized gaze is what makes the conversation physical — you can see it paying attention.

It's yours.

No account. No subscription for anything local. The device is yours the way a good tool is yours.

Your bench stays yours.

A bench instrument, not a gadget.

It's also an MCP server.

Harness is an MCP server on your network. Your own agents can see through it, hear through it, and speak through it. If your agent can call tools, it can use the bench.

No date yet — we won't name one we can't keep. Seven months of hardware work are in the dated build log. The list hears the date first, and you'll see the working prototype before we ever ask for a deposit.

Is there a subscription? An account? A cloud?

No account and no subscription for anything that runs on the device. For heavier reasoning, point it at your own model and key.

What does "it is an MCP server" mean?

Harness is an MCP server on your network. An agent can capture a frame, listen and transcribe, speak, and run an ask-and-answer turn in one call. Full list at /mcp.

Do I need to know electronics?

No. Plug in USB-C, paste a model key once — Claude, GPT, or a free local model via Ollama — then double-tap and talk.

What does it cost?

No honest number yet — the bill of materials for the first run is still being priced. The list hears the real price first, with the reasoning attached.

What does "bring your own model" mean?

The device handles waking, listening, and turning to look on its own. For the thinking it talks to a model you choose: any OpenAI-compatible endpoint — Claude, GPT, or a local model on your own machine via Ollama — with your own key.

What if I don't have a key?

It still wakes, listens and turns to look. Without a model to think with it can't answer — a key from any OpenAI-compatible provider, or a free local model via Ollama, turns the thinking on.

What can't it do?

It can't see through enclosures, read your mind, or replace a multimeter. Small text under a centimeter is a coin flip. It's a second pair of eyes, not a certification.
