7 TOOLS AVAILABLE
OUR ASSESSMENT
- 2,770 GitHub stars.
- 100 commits on main in the last 30 days.
- MIT license.
- Comprehensive tool surface across entities, services, automations.
- First smart-home MCP in the directory.
- Home Assistant instance required; cloud or self-hosted.
- Long-lived access token carries full HA permissions; scope token usage carefully.
- Community-maintained; no Home Assistant vendor stamp.
HA_TOKEN is a long-lived access token with admin-level capabilities by default. Use a dedicated user account scoped to the agent flow. call_service can invoke any registered service (lights, locks, security alarms); restrict the agent prompt path or use Home Assistant's built-in user permissions to limit reachable services.
Smart-home enthusiasts running Home Assistant who want agents to control devices via natural language; energy-monitoring flows where the agent triages state changes; security flows where the agent reads sensor states and triggers automations.

SOURCES & VERIFICATION
We don't take any single directory's word for it. Before scoring, we cross-reference 4 public MCP sources, install the server ourselves against the clients we cover, and record when we last re-verified.
The same server, 4 different lenses. We reconcile these signals into our editorial score, which is why our number sometimes diverges from a directory-aggregate star count.
