Fibaro HC3 MCP Server

Overview

The Fibaro HC3 MCP server bridges the gap between natural‑language AI assistants and a home automation hub. By exposing Fibaro Home Center 3’s RESTful API through the Model Context Protocol, it allows assistants such as Claude Desktop to query and manipulate rooms, devices, scenes, and system state using plain‑English commands. This eliminates the need for custom scripts or manual web‑hooks, giving developers a unified interface to control a complete smart‑home ecosystem.

The server implements a rich set of tools that mirror the HC3’s capabilities. Developers can list and inspect rooms or devices, retrieve detailed device properties, and invoke any action the hub supports—turning lights on or off, adjusting dimmers, or setting thermostat values. Scene management tools let assistants list available scenes, inspect their configuration, execute them synchronously or asynchronously, and even terminate a running scene. A lightweight tool provides quick diagnostics to confirm that the hub is reachable and credentials are valid. These tools are described in MCP’s standard JSON schema, so any compliant client can discover and call them without prior knowledge of Fibaro’s internal structure.

In real‑world scenarios, this server is invaluable for building voice‑controlled or chat‑based home automation. A user could simply type “Set bedroom lamp to 10%” or ask the assistant to “Turn on all lights in the living room,” and the MCP server translates that into the appropriate HC3 API calls. Because the server runs locally, latency is minimal and sensitive data never leaves the home network. Developers can also compose complex automation flows by chaining tool calls: first retrieve a device’s current state, then decide whether to toggle it based on a condition.

Integration with AI workflows is straightforward. For desktop assistants that support STDIO transport, the server runs as a child process and exchanges JSON messages over standard input/output. HTTP‑based clients can instead use the server’s SSE endpoint for real‑time notifications and a POST endpoint for command execution. Authentication is optional but recommended; an API key protects the HTTP interface from unauthorized access.

Unique advantages of this MCP server include its zero‑code approach to home automation: developers need only configure environment variables, and the toolset is auto‑generated from Fibaro’s API. The server also supports both synchronous and asynchronous scene execution, giving assistants flexibility in how they handle long‑running automations. By providing a single point of integration, the Fibaro HC3 MCP server empowers developers to build sophisticated, conversational home‑control experiences without wrestling with proprietary SDKs or custom integrations.
