# LabWired

> The easy way to build hardware. Design circuits, run real firmware in the browser, compare variants in Playground, and reuse the same models in CI. Agents connect through MCP (Claude, Codex, and other MCP clients).

LabWired is an open-source (MIT) Rust core with a hosted Playground and a hosted MCP connector. Humans and agents use the same simulation surface: pins, buses, displays, UART, and deterministic traces.

## Product surfaces

- [Pricing](https://labwired.com/pricing.html): Starter $9, Pro $39, Enterprise (talk to us)
- [For CI](https://labwired.com/ci.html): deterministic firmware CI without a HIL bench
- [Library](https://labwired.com/library.html): chips, boards, and peripherals catalog

## MCP (primary agent path)

Hosted connector (preferred):

```text
https://api.labwired.com/mcp
```

Install examples:

```bash
claude mcp add labwired --transport http https://api.labwired.com/mcp
codex mcp add labwired --url https://api.labwired.com/mcp
```

Local developer package (optional): `npx -y @labwired/mcp`

## What agents can do

1. Describe a device or pick a lab (STM32, ESP32, RP2040, nRF, sensors, displays).
2. Assemble or load a virtual board (YAML/system configs + firmware).
3. Run firmware in simulation; inspect UART, displays, bus traffic, and traces.
4. Open the same setup in Playground for a human to watch.
5. Hand off to CI for deterministic JSON / VCD / UART evidence.

## Example agent prompt

> Connect LabWired over MCP. Build or load a virtual STM32 LED + UART board, run the firmware, validate the result, and open the Playground URL so I can inspect it.
