history_query
State changes by entity + hours (not ISO timestamps)
How to use it
Project documentation lists history_query for the Homeassistant MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
