What is the ESPHome MCP Server?
Connect your ESPHome microcontrollers to any AI agent and take full control of your smart home or industrial IoT setup through natural conversation.
What you can do
- Real-time Monitoring — Fetch the current state and values of any sensor, switch, or binary sensor using the
get_entity_statetool. - Lighting Control — Manage lights with precision using
light_action, including brightness and RGB color adjustments. - Appliance Management — Toggle switches, control fans with
fan_action, and adjust covers (blinds/garage doors) withcover_action. - Interactive Components — Press buttons via
button_press, set numeric values withnumber_set, and choose options from dropdowns withselect_option. - Security & Safety — Arm or disarm alarm panels using
alarm_actiondirectly from your chat interface.
How it works
- Enable the
web_servercomponent in your ESPHome YAML configuration. - Subscribe to this server.
- Enter your device's local URL and optional password.
- Start interacting with your hardware from Claude, Cursor, or any MCP client.
Who is this for?
- Home Automation Enthusiasts — control your local environment without complex dashboards.
- IoT Developers — test and debug ESP32/ESP8266 entity behaviors using natural language.
- Hardware Engineers — monitor sensor metrics and trigger actions during prototyping phases.

Frequently asked questions
Can I control my lights and set specific colors using this server?
Yes! Use the light_action tool. You can specify the entity name, the action (turn_on), and optional parameters like brightness (0-255) and RGB values (r, g, b) to get the perfect ambiance.
How do I check the current temperature or humidity from my sensors?
Simply use the get_entity_state tool. Provide the domain (e.g., 'sensor') and the entity ID. The agent will return the current value and state of that specific hardware component.
Is it possible to trigger a physical button or restart a device?
Yes. If you have a button entity configured in ESPHome (like a restart button), you can use the button_press tool with the entity name to trigger that action remotely.
How does Claude Desktop discover MCP tools?
When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.
What happens if the MCP server is temporarily unavailable?
Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.
Can I connect multiple MCP servers simultaneously?
Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.
Is there a limit on the number of tools per server?
Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.
Does Claude Desktop support Streamable HTTP transport?
Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
Server not appearing after restart
Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).
Authentication error
Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.
Tools not showing in chat
Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
