mcp-airq-cloud

MCP server for the air-Q Cloud API — access air quality data from anywhere.

Unlike mcp-airq (which communicates directly with devices on the local network), this server uses the air-Q Cloud REST API to retrieve sensor data remotely.

The same mcp-airq-cloud executable also works as a direct CLI when you pass a tool name as a subcommand.

Tools

Tool	Description
list_devices	List configured air-Q Cloud devices
get_air_quality	Get latest sensor readings (supports device/location/group selection)
get_air_quality_history	Get historical data within a time range as column-oriented JSON
plot_air_quality_history	Render one historical chart per sensor across all matching devices
export_air_quality_history	Export one historical sensor as one csv or xlsx across matching devices

All tools are read-only — the Cloud API does not support device configuration or control.

Installation

pip install mcp-airq-cloud

Or install from source:

git clone https://github.com/CorantGmbH/mcp-airq-cloud.git
cd mcp-airq-cloud
uv sync --frozen --extra dev

CLI Usage

Use the same command directly from the shell:

mcp-airq-cloud list-devices
mcp-airq-cloud get-air-quality --device "Living Room"
mcp-airq-cloud get-air-quality-history --device "Living Room" --last-hours 24 --sensors co2 pm2_5
mcp-airq-cloud plot-air-quality-history --sensor co2 --output-format png --output co2.png
mcp-airq-cloud export-air-quality-history --sensor co2 --output-format xlsx --output co2.xlsx

For historical plots and exports:

• omit device, location, and group to combine all configured devices into one artifact
• use location or group to combine only the matching devices
• plot_air_quality_history returns one file per requested sensor, with one series per matching device
• export_air_quality_history returns one CSV/XLSX file per request, with rows for all matching devices

The CLI subcommands mirror the MCP tool names. Both styles work:

mcp-airq-cloud list-devices
mcp-airq-cloud list_devices

To force MCP server mode from an interactive terminal, run:

mcp-airq-cloud serve

The CLI is pipe-friendly: successful command output goes to stdout, while tool errors go to stderr with exit code 1. Plot commands can also stream directly to stdout.

mcp-airq-cloud get-air-quality --device "Living Room" | jq '.co2'
mcp-airq-cloud get-air-quality-history --device "Living Room" --compact-json | jq '.columns.co2'
mcp-airq-cloud get-air-quality-history --device "Living Room" --yaml | yq '.columns.co2'
mcp-airq-cloud plot-air-quality-history --sensor co2 --device "Living Room" --output - > co2.png
mcp-airq-cloud export-air-quality-history --sensor co2 --device "Living Room" --output - > co2.xlsx

Historical Data

Three tools provide access to historical sensor data via the air-Q Cloud API:

Plotting charts

plot_air_quality_history renders a chart for one sensor. When multiple devices match, each device becomes a separate series in the same chart.

Single device (24 h, area chart, PNG)

Multiple devices at one location (24 h, area chart, PNG)

# Single device, last 24 hours (default), PNG output (default)
mcp-airq-cloud plot-air-quality-history --sensor co2 --device "Living Room"

# All devices at a location, custom time range, SVG output
mcp-airq-cloud plot-air-quality-history --sensor co2 --location "Living Room" \
  --from-datetime "2026-03-16T00:00:00" --to-datetime "2026-03-17T00:00:00" \
  --output-format svg --output co2.svg

# All configured devices, dark mode, line chart
mcp-airq-cloud plot-air-quality-history --sensor co2 --dark --chart-type line

# Save to file
mcp-airq-cloud plot-air-quality-history --sensor co2 --output co2_chart.png

Output formats: png (default), webp, svg, html (interactive Plotly chart with hover tooltips and zoom)

Customization: --title, --x-axis-title, --y-axis-title, --chart-type (line/area), --dark, --timezone-name

Exporting data

export_air_quality_history produces one CSV or Excel file containing all matching devices.

# CSV export (default)
mcp-airq-cloud export-air-quality-history --sensor co2 --device "Living Room" --last-hours 48

# Excel export for all devices at a location
mcp-airq-cloud export-air-quality-history --sensor co2 --location "Home" \
  --output-format xlsx --output co2.xlsx

Common parameters

Parameter	Default	Description
--last-hours	1 (history) / 24 (plot)	Hours of data to retrieve
--from-datetime / --to-datetime	—	ISO 8601 time range (overrides --last-hours)
--max-points	300	Downsample to at most N evenly spaced points
--timezone-name	UTC	IANA timezone for timestamps (e.g. Europe/Berlin)

Configuration

You need a Cloud API key and the 32-character device ID for each device. Both can be obtained at my.air-q.com.

Option 1: Environment variable (inline JSON)

export AIRQ_CLOUD_DEVICES='[{"id": "de45d2ed777780c96c0deae7a220b745", "api_key": "your-api-key", "name": "Living Room"}]'

Option 2: Default config file (recommended)

Place a JSON file at ~/.config/airq-cloud-devices.json — no environment variable needed:

[
  {"id": "de45d2ed777780c96c0deae7a220b745", "api_key": "your-api-key", "name": "Living Room"}
]

Option 3: Custom config file path

export AIRQ_CLOUD_CONFIG_FILE=/path/to/devices.json

Option 4: Global API key

If all devices share the same API key, set it once:

export AIRQ_CLOUD_API_KEY="your-api-key"
export AIRQ_CLOUD_DEVICES='[{"id": "de45d2ed777780c96c0deae7a220b745", "name": "Living Room"}]'

Device config fields

Field	Required	Description
id	yes	32-character cloud device ID
api_key	no	Per-device API key (falls back to AIRQ_CLOUD_API_KEY)
name	no	Friendly name (defaults to first 8 chars of ID)
location	no	Location for grouping (e.g. "Wohnzimmer")
group	no	Group for grouping (e.g. "zu Hause")

Usage with Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "air-Q Cloud": {
      "command": "mcp-airq-cloud",
      "env": {
        "AIRQ_CLOUD_DEVICES": "[{\"id\": \"<device-id>\", \"api_key\": \"<key>\", \"name\": \"Living Room\"}]"
      }
    }
  }
}

Usage with Claude Code

claude mcp add air-Q-Cloud mcp-airq-cloud \
  -e AIRQ_CLOUD_DEVICES='[{"id":"<ID>","api_key":"<KEY>","name":"<Name>"}]'

Development

uv sync --frozen --extra dev
uv run pre-commit install
uv run pytest

The repository uses a project-local .venv plus uv.lock for reproducible tooling. Run developer commands through uv run, for example:

uv run ruff check .
uv run ruff format --check .
uv run pyright
uv run pre-commit run --all-files
