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.
## Usage
```shell
# Get states
mcporter call home-assistant.GetLiveContext
# Turn on the device
mcporter call home-assistant.HassTurnOn(name: "Bedroom Light")
mcporter call home-assistant.HassTurnOn(name: "Light", area: "Bedroom")
# Turn off the device
mcporter call home-assistant.HassTurnOff(name: "Bedroom Light")
mcporter call home-assistant.HassTurnOff(area: "Bedroom", domain: ["light"])
# Control light
# brightness: The percentage of the light, where 0 is off and 100 is fully lit.
# color: Name of color
mcporter call home-assistant.HassLightSet(name: "Bedroom Light", brightness: 50)
# Control fan
# percentage: The percentage of the fan, where 0 is off and 100 is full speed.
mcporter call home-assistant.HassFanSetSpeed(name: "Fan", area: "Bedroom", percentage: 80)
```
Execute the following command to learn about specific usage methods:
- `mcporter list home-assistant --schema --all-parameters`

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
mcporter config add home-assistant \
--transport http \
--url "${HASS_BASE_URL:-http://homeassistant.local:8123}/api/mcp" \
--header "Authorization=Bearer \${HASS_ACCESS_TOKEN}"
```

Meeting Prep
Never walk into a meeting unprepared again. Your agent researches all attendees before calendar events—pulling LinkedIn profiles, recent company news, mutual connections, and conversation starters. Generates a briefing doc with talking points, icebreakers, and context so you show up informed and confident. Triggered automatically before meetings or on-demand. Configure research depth, advance timing, and output format. Walking into meetings blind is amateur hour—missed connections, generic small talk, zero leverage. Use when setting up meeting intelligence, researching specific attendees, generating pre-meeting briefs, or automating your prep workflow.
self-improvement
Captures learnings, errors, and corrections to enable continuous improvement. Use when: (1) A command or operation fails unexpectedly, (2) User corrects Claude ('No, that's wrong...', 'Actually...'), (3) User requests a capability that doesn't exist, (4) An external API or tool fails, (5) Claude realizes its knowledge is outdated or incorrect, (6) A better approach is discovered for a recurring task. Also review learnings before major tasks.
