What it does
Home Assistant has included a Model Context Protocol Server integration since release 2025.2, which makes a Home Assistant instance itself an MCP server. Once the integration is added, clients such as Claude, ChatGPT, Claude Code, Codex and OpenCode connect to the instance's /api/mcp address and sign in with OAuth. One tool set offers the Assist device-control tools, limited to entities exposed to voice assistants; another can read all entities, logs and history and perform any action, and always needs an administrator account. Options include a read-only mode. Prompts and tools are supported; sampling and notifications are not.
Capabilities
- Control devices exposed to Assist
- Read entity states, logs and history
- Perform Home Assistant actions (administrator only)
- Run in read-only mode
