The skill for control Home Assistant smart home devices and query states using MCP protocol.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Home Assistant
Control Home Assistant smart home and query states using MCP protocol.
## Prerequisites
Enable MCP server in Home Assistant:
- Browse to your Home Assistant instance.
- Go to Settings > Devices & services.
- In the bottom right corner, select the [+ Add Integration](https://my.home-assistant.io/redirect/config_flow_start?domain=mcp) button.
- From the list, select Model Context Protocol.
- Follow the instructions on screen to complete the setup.
## Config
When prompted that the MCP server does not exist, remind the user to configure the `HASS_BASE_URL` and `HASS_ACCESS_TOKEN` environment variables by executing the following command to add the configuration:
```shell
npx -y mcporter config add home-assistant \
--transport http \
--url "${HASS_BASE_URL:-http://homeassistant.local:8123}/api/mcp" \
--header "Authorization=Bearer \${HASS_ACCESS_TOKEN}"
```
## Usage
```shell
# Get states
npx -y mcporter call home-assistant.GetLiveContext
# Turn on the device
npx -y mcporter call home-assistant.HassTurnOn(name: "Bedroom Light")
npx -y mcporter call home-assistant.HassTurnOn(name: "Light", area: "Bedroom")
# Turn off the device

How to install
mdr add aahl/skills/mcp-hass@sha256:4008679d7cbb3066The line at the top of this page pins the label git:20260224.81058ce, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
