Control ESP32 IoT devices from AI agents: status, GPIO, ADC, reboot.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

Common questions

Is ESP32 Control safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 30 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code.

What can I use instead?

ESP32 MCP Server

Control and read ESP32 IoT devices directly from AI agents (Claude, Cursor, any MCP client).

  • esp32.status — online / chip / free heap / uptime
  • esp32.gpio_set — set a GPIO high/low
  • esp32.gpio_read — read a digital pin
  • esp32.adc_read — read analog voltage (mV)
  • esp32.send_command — raw AT/application command
  • esp32.reboot — reboot the device

Architecture

AI agent (Claude/Cursor)  →  this MCP server (Python)  →  ESP32 REST API  →  device

The ESP32 runs a tiny MicroPython firmware (esp32_firmware/main.py) exposing a lightweight REST API on port 80. The MCP server talks to it over HTTP — works locally and remotely.

Quick start

1. Flash the ESP32 firmware
  1. Install MicroPython on your ESP32.
  2. Upload esp32_firmware/main.py as main.py (Thonny or mpremote).
  3. Power on — the device opens a WiFi AP named ESP32-MCP (password 12345678) or you can set STA mode inside the firmware to join your network.
2. Run the MCP server
pip install esp32-mcp

export ESP32_HOST=http://192.168.4.1 # device address (AP default) esp32-mcp # stdio transport (local MCP client)

For remote agents, run with HTTP transport:

uv run esp32-mcp --transport http --port 8000
3. Add to your AI client

Claude Desktop (claude_desktop_config.json):

{

"mcpServers": { "esp32": { "command": "esp32-mcp", "env": { "ESP32_HOST": "http://192.168.4.1" } } } }

Cursor: Settings → MCP → Add server → esp32-mcp with env ESP32_HOST.

Then just ask: *"turn GPIO 2 on"*, *"what's the ADC reading on pin 34?"*, *"reboot the device"*.

Configuration

Env varDefaultMeaning
ESP32_HOSThttp://192.168.4.1ESP32 REST endpoint
ESP32_TIMEOUT8request timeout (s)

Safety

  • GPIO outputs are limited to pins 2, 4, 5, 18, 19 by default (edit GPIO_OUT in the firmware to change).
  • The firmware only listens on its own network; change the AP password before exposing to the internet.
