How to Use the Home Assistant MCP in Cursor

Q: Can Cursor read my Home Assistant log files?

The agent uses getlogbookentries to read system events. You can filter these entries by specific entity IDs and time ranges to debug failing scripts.

Q: How do I find the correct service parameters for a new integration?

Have the agent run listavailableservices. It returns every valid domain, service, and required parameter currently supported by your installation.

Give Cursor live access to your smart home state to write perfect automation scripts.

Perplexity

Build automations with live MCP Server data

`list_entity_states` gives Cursor exact entity IDs and current attributes while you write code. Your MCP server pulls real device names from your network instead of hallucinating placeholder variables. You write Python scripts or AppDaemon apps using the actual data structures your instance generates. `call_ha_service` tests the climate.set_temperature command immediately when you write a function to control the HVAC. Testing service payloads happens inside the IDE. The AI agent verifies the JSON structure against your live setup before you commit a single line.

Debug templates and configuration files

`render_ha_template` executes Jinja2 logic directly against your live database. You highlight a block of template code in your editor, and the agent processes it to show you the exact output. This catches syntax errors and missing variables before you restart the core service. `check_ha_configuration` runs the native validation check on your YAML files. Validating your changes takes one command. If there is a syntax error in your configuration file, the agent reads the error and fixes the indentation right in your workspace.

Inspect component and event structures

`list_ha_components` pulls every loaded integration currently active on your network. Your AI client checks this list to ensure required dependencies exist before writing new automation logic. It prevents you from writing code for integrations that failed to load. `list_ha_events` dumps the registered event types, while `fire_ha_event` lets you simulate triggers. Event-driven programming requires knowing the exact trigger names. You test your custom event listeners by firing payloads from the editor and watching your code respond.

Setup guide

Set up Home Assistant MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Home Assistant MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Home Assistant transactions." If the MCP tools are loaded correctly, Cursor will call the Home Assistant tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "home-assistant-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }

Common questions about Home Assistant MCP in Cursor

Create an mcp.json file in your project root or global .cursor directory. Define the server path and your long-lived access token. Switch the chat to Agent mode to start querying your devices.

The agent uses get_logbook_entries to read system events. You can filter these entries by specific entity IDs and time ranges to debug failing scripts.

Cursor edits the YAML or Python files in your local workspace. You must still deploy those files to your actual server. It uses get_ha_config to read your current setup details.

Have the agent run list_available_services. It returns every valid domain, service, and required parameter currently supported by your installation.

This connection accesses your HVAC schedules, lighting routines, and security camera triggers. Vinkius isolates this data in a zero-trust execution layer. We handle the endpoint token routing, but we never store your device states or configuration payloads.
