About Home Assistant MCP (ha-mcp)
ha-mcp lets AI assistants control smart home devices, query states, call services and manage automations in Home Assistant through natural language. The recommended install is a custom component from HACS that runs the server inside Home Assistant on every installation type, with no access token to manage; Docker, uvx and an add-on are alternatives. It is not an official Home Assistant project.
Home Assistant MCP (ha-mcp) is listed in this index written primarily in Python, with 5.4k stars on GitHub. Its latest recorded repository push was in November 2026; that is not an ASE editorial review date.
Before connecting: access and data
This record's specific permissions have not been reviewed by ASE. Read the publisher's documentation before copying setup or connecting.
- List the accounts, files and services the enabled tools can read, change or execute. Check your actual credentials and discovered tools.
- Use narrowly scoped credentials and read-only mode where supported. Review proposed writes before approving them; a generated configuration does not apply these limits for you.
- Local launch is not local-only data processing. External services receive requests, and your client may pass tool results to its model provider. Check both destinations before sharing private data.
- Keep keys and browser session files out of shared config, repositories and screenshots. Know how to disconnect the server and separately revoke its credentials or account sessions.
