Temp Stick MCP server by OpenPandora — let your AI assistant check your freezer and temperature sensors.

New to this? Follow the plain-words setup guide — five minutes, short steps, no jargon.

tempstick-mcp is a free, open-source Model Context Protocol (MCP) server for Temp Stick WiFi temperature sensors by Ideal Sciences — a freezer monitor and temperature sensor reader for your AI assistant. It was built for restaurant kitchens (nobody wants to discover a warm walk-in at 6 AM), and it works anywhere a Temp Stick watches something that matters: freezers, fridges, server rooms, greenhouses, homes. Connect it to Claude, Cursor, or any MCP client and just ask:

"What's my freezer at right now?" "Has the walk-in been above 40°F today?" "Is any sensor offline or low on battery?"

The server answers with live data from the official Temp Stick API: temperature (Celsius and Fahrenheit), humidity, battery level, offline status, alert definitions, and recent-reading summaries.

• Zero dependencies. Pure Python 3 standard library — no pip install of anything. Clone, add your key, go.
• Read-only. It cannot change a setting, a threshold, or an alert on your account.
• Private by design. Your API key stays on your machine in an environment variable. The server talks only to tempstickapi.com.

Tools

A command-line twin is included for terminal checks and cron jobs: tempstick.py list-sensors, latest --sensor <ID>, history --sensor <ID>, alerts, freezer --sensor <ID>.

Install

git clone https://github.com/obseard223/tempstick-mcp

Claude Desktop

Add to your claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json; Windows: %APPDATA%\Claude\claude_desktop_config.json):

{  "mcpServers": {    "tempstick": {      "command": "python3",      "args": ["/path/to/tempstick-mcp/server.py"],      "env": { "TEMPSTICK_API_KEY": "paste-your-key-here" }    }  }}

Restart Claude Desktop, then ask: "List my Temp Stick sensors."

Claude Code

claude mcp add tempstick \  --env TEMPSTICK_API_KEY=paste-your-key-here \  -- python3 /path/to/tempstick-mcp/server.py

Cursor

Add to .cursor/mcp.json in your project (or the global MCP config):

{  "mcpServers": {    "tempstick": {      "command": "python3",      "args": ["/path/to/tempstick-mcp/server.py"],      "env": { "TEMPSTICK_API_KEY": "paste-your-key-here" }    }  }}

On Windows, use python instead of python3 (and a Windows-style path).

Test it offline

No key, no network:

python3 selftest.py            # full end-to-end test against a stub APIpython3 tempstick.py selftest  # parsing/unit checks only

Both should end in PASS.

Notes on the API

A few behaviors of the Temp Stick API this server handles for you:

• Errors come back as HTTP 200 with a JSON envelope (type: "error"), so the server checks the envelope and surfaces the real message — e.g. Invalid X-API-KEY.
• Temperatures arrive in Celsius; every reading is also reported in Fahrenheit.
• The API host rejects non-browser user agents, so the server sends a browser user agent.

Status

Community project, built against the official Temp Stick API. It is not affiliated with or endorsed by Ideal Sciences or Temp Stick. The parsing and protocol layers are covered by offline fixture tests (see selftest.py); readings and alerts shapes beyond the documented fields are parsed defensively.

Built by OpenPandora

Built by OpenPandora — AI tools for independent restaurants. This is the same sensor watch that keeps an eye on our pilot kitchen's walk-in freezer, released free because every operator with a Temp Stick should be able to ask their AI about it.
