About Home Assistant MCP
Home Assistant ships a first-party MCP Server integration that exposes your exposed entities (lights, locks, climate, sensors, scenes and scripts) to any MCP client. Because Home Assistant runs locally, the whole loop stays on your network, which matters for a smart home where cloud latency and outages are real problems. You control exactly which entities are visible through Home Assistant's existing Assist exposure settings.
Home Assistant MCP is a APIs & Data MCP server designed for engineers and ops teams. It enables connecting AI assistants to third-party APIs and data feeds by wrapping HTTP endpoints with auth and schema as MCP tools. Key capabilities include auth helpers for common providers, pagination and rate-limit handling, endpoint allow-lists, and structured tool calls that work cleanly inside an LLM context. It integrates with Salesforce, HubSpot, Mixpanel, Stripe, and most REST/GraphQL APIs, and is best suited for engineers and ops teams who need internal admin apis.

Our Take on Home Assistant MCP
A rare fully-local MCP server. Setup is fiddlier than a hosted one, but nothing leaves your network.
