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_state tool.
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) with cover_action.
Interactive Components — Press buttons via button_press, set numeric values with number_set, and choose options from dropdowns with select_option.
Security & Safety — Arm or disarm alarm panels using alarm_action directly from your chat interface.

How it works

Enable the web_server component 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.

Why Cursor?

Cursor's Agent mode turns ESPHome into an in-editor superpower. Ask Cursor to generate code using live data from ESPHome and it fetches, processes, and writes. all in a single agentic loop. 10 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.

—
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
—
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
—
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
—
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

FAQ

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.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
