## What it does

This server runs through `npx -y @jettyd/mcp` and bridges MCP clients with ESP32 hardware fleets. It supplies the agent with five tools: `list_devices`, `read_device`, `send_command`, `get_telemetry`, and `push_rules`.

The assistant can check connected hardware, read immediate sensor values, and fetch telemetry history over defined intervals. It also transmits direct commands to outputs such as relays or LEDs and installs JettyScript automation routines directly on the controllers.

Running the server requires a valid `JETTYD_API_KEY` from `jettyd.com`, supplied through the client environment variables.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `JETTYD_API_KEY`, `JETTYD_BASE_URL` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

### Claude Code (native platform)

## When to use it
- retrieve live temperature and humidity metrics from an ESP32
- trigger relays or LED indicators with duration parameters
- inspect historical telemetry trends across recent hours
- deploy JettyScript automation routines to connected hardware

## Example prompts
- Check the current greenhouse temperature on the sensor
- Turn on the irrigation relay for 30 seconds
- Fetch humidity telemetry data for the last 24 hours
