How to Set Up and Use Grocy
The Grocy MCP server provides a complete integration with the Grocy self-hosted household management API, enabling AI assistants to manage inventory, shopping lists, meal planning, chores, and more. It connects directly to your Grocy instance using your personal API key, making it possible to query stock levels, add items, and automate home management tasks from an AI chat interface. This is especially useful for households running Grocy who want to interact with their data through natural language rather than the Grocy web UI.
Prerequisites
- Node.js 18 or later installed
- A running Grocy instance (self-hosted) with a valid API key
- The Grocy base URL accessible from your machine
- An MCP-compatible client such as Claude Desktop
Clone the repository
Clone the mcp-grocy-api repository from GitHub and navigate into the project directory.
git clone -b main https://github.com/saya6k/mcp-grocy-api.git
cd mcp-grocy-apiInstall dependencies and build
Install Node.js dependencies and compile the TypeScript source.
npm install
npm run buildLocate your Grocy API key
In your Grocy web interface, go to Settings → Manage API keys to generate or copy your API key. Note the base URL of your Grocy instance (e.g., http://192.168.1.100:9283 or https://grocy.yourdomain.com).
Set environment variables
Export the required environment variables before running the server. GROCY_BASE_URL is your Grocy instance URL and GROCY_APIKEY_VALUE is your API key. Optionally set GROCY_ENABLE_SSL_VERIFY to false if using self-signed certificates.
export GROCY_BASE_URL=http://your-grocy-instance
export GROCY_APIKEY_VALUE=your_api_keyConfigure your MCP client
Add the server to your Claude Desktop (or other MCP client) configuration file with the environment variables set inline.

}
}
}
}Verify the connection
Restart your MCP client and ask a question that touches Grocy data to verify connectivity, such as asking about current stock levels.

"mcpServers": {
"grocy": {
"command": "npx",

"env": {
"GROCY_BASE_URL": "http://192.168.1.100:9283",

"GROCY_ENABLE_SSL_VERIFY": "true",
"REST_RESPONSE_SIZE_LIMIT": "10240"
}
}
}
}Prompts to try
Example natural language prompts to use with Claude after connecting the Grocy MCP server.
- "What products are currently low in stock in my Grocy inventory?"
- "Add 2 liters of whole milk to my shopping list."
- "What meals are planned for this week in my meal plan?"
- "Which chores are overdue in Grocy?"
- "Show me all items expiring in the next 7 days."Troubleshooting Grocy
Connection refused or timeout when reaching Grocy
Verify GROCY_BASE_URL is correct and reachable from your machine. If Grocy runs on a local network IP, make sure there is no firewall blocking the port. Test with curl: curl -H 'GROCY-API-KEY: your_key' http://your-grocy-instance/api/system/info
SSL certificate verification errors
If your Grocy instance uses a self-signed certificate, set GROCY_ENABLE_SSL_VERIFY=false in the environment configuration. Only do this on trusted local networks.
Response truncated or incomplete data returned
The default REST_RESPONSE_SIZE_LIMIT is 10KB. If Grocy returns large datasets (many products, long history), increase this value, e.g., REST_RESPONSE_SIZE_LIMIT=51200 for 50KB.
