What it does
MCP Hass is an agent skill from aahl/skills. The skill for control Home Assistant smart home devices and query states using MCP protocol.
Its SKILL.md is about 570 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol and Home Assistant. The repository describes itself as: AAHL's Agent Skills. 汇集了多种实用的智能体技能，涵盖Home Assistant智能家居控制、微软Edge TTS和智谱GLM-TTS文本转语音、DuckDuckGo搜索、DeepWiki文档检索、加密货币行情、天气预报、Lark/飞书、影视搜索、商品比价等功能. The licence is MIT.
When your agent uses it
- Tasks that involve MCP servers
Example prompts
- “/mcp-hass”
Requirements
- Node.js
- A credential in HASS_ACCESS_TOKEN
What it can do on your machine
Read from SKILL.md and the folder at commit 47edd62. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
HASS_ACCESS_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
MCP Hass loads about 568 tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 122 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 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:
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
# 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
npx -y mcporter call home-assistant.HassTurnOff(name: "Bedroom Light")
npx -y 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
npx -y 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.
npx -y mcporter call home-assistant.HassFanSetSpeed(name: "Fan", area: "Bedroom", percentage: 80)Execute the following command to learn about specific usage methods:
npx -y mcporter list home-assistant --schema --all-parameters
