Pick Home Assistant MCP if
- ✅ Broad domain coverage — lights, climate, covers, media, locks, vacuums, cameras, and more mapped to MCP tools out of the box
- ✅ Real-time SSE subscriptions let an LLM react to state changes and automation triggers, not just poll
- ✅ Docker Compose setup and clear env-var config make it easy to run alongside an existing Home Assistant install
- ✅ Exposes system-level surfaces most HA wrappers skip: add-on management, HACS package installs, automation CRUD
Pick MCP Everything Server if
- ✅ Only server that exercises the full MCP feature matrix in one place — tools, resources, prompts, sampling, elicitation, roots, logging, subscriptions, and Tasks
- ✅ Maintained by the Model Context Protocol project itself, so behavior tracks the spec as it evolves (SEP-1686 Tasks, Streamable HTTP, etc.)
- ✅ Runs anywhere an MCP client runs — npx, Docker, Claude Desktop, VS Code, Cursor, Windsurf — with stdio or HTTP transports
- ✅ TypeScript source is short and readable, making it a de-facto reference for how each handler should be shaped
