Enable Cursor, VS Code, Claude Code or any MCP-enabled IDE to help you vibecode and manage Home Assistant: create automations, design dashboards
Enable Cursor, VS Code, Claude Code or any MCP-enabled IDE to help you vibecode and manage Home Assistant: create automations, design dashboards, tweak themes, modify configs, and deploy changes using natural language. That is what the home mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
You describe your goal → AI inspects your Home Assistant → designs a custom solution → and deploys it on-board automatically. 🚀
Installation goes through your MCP client rather than a global install: point it at ENOENT on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
The server publishes 4 tools. What each one is for:
Variable — DescriptionHA_AGENT_URL — URL of HA Vibecode AgentHA_AGENT_KEY — Agent Key for authenticationArchitecture — The Architecture tool exposed by this serverConfiguration is passed through the environment: HA_AGENT_URL, HA_AGENT_KEY, SUPERVISOR_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Home's toolset — Variable, HA_AGENT_URL, HA_AGENT_KEY and 1 more — is a fair guide to whether it matches your workflow. It is maintained by GitHub Actions; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
