Features

• Dynamic API Discovery - Automatically discovers and exposes all available Spruthub JSON-RPC methods

• Schema Validation - Built-in parameter validation and documentation for all API methods

• Full API Coverage - Access to all Spruthub functionality including devices, rooms, scenarios, and system administration

• WebSocket Connection - Secure connection to Spruthub server with authentication

• Method Categories - Organized API methods by category (hub, accessory, scenario, room, system)

• Real-time Schema Updates - Schema information updated with spruthub-client library versions

• Structured Responses - JSON-formatted responses optimized for AI integration

Installation

Using npx (Recommended)

Run the MCP server directly using npx:

npx spruthub-mcp-server

Using Claude Desktop

Add to your Claude Desktop MCP settings:

{
  "mcpServers": {
    "spruthub": {
      "command": "npx",
      "args": ["spruthub-mcp-server"],
      "env": {
        "SPRUTHUB_WS_URL": "wss://your-spruthub-server.com/ws",
        "SPRUTHUB_EMAIL": "your-email@example.com",
        "SPRUTHUB_PASSWORD": "your-password",
        "SPRUTHUB_SERIAL": "your-device-serial"
      }
    }
  }
}

Development

For development or local modifications:

git clone https://github.com/shady2k/spruthub-mcp-server.git
cd spruthub-mcp-server
npm install

Usage

As an MCP Server

Add this server to your MCP client configuration. For Claude Desktop, add to your claude_desktop_config.json:

Using npm package (recommended):

{
  "mcpServers": {
    "spruthub-mcp-server": {
      "command": "npx",
      "args": [
        "spruthub-mcp-server@1.3.9"
      ],
      "env": {
        "SPRUTHUB_WS_URL": "ws://192.168.0.100/spruthub",
        "SPRUTHUB_EMAIL": "your_email@example.com",
        "SPRUTHUB_PASSWORD": "your_password",
        "SPRUTHUB_SERIAL": "AAABBBCCCDDDEEEF"
      }
    }
  }
}

For local development:

{
  "mcpServers": {
    "spruthub-mcp-server": {
      "command": "node",
      "args": ["/path/to/spruthub-mcp-server/src/index.js"],
      "env": {
        "SPRUTHUB_WS_URL": "ws://192.168.0.100/spruthub",
        "SPRUTHUB_EMAIL": "your_email@example.com", 
        "SPRUTHUB_PASSWORD": "your_password",
        "SPRUTHUB_SERIAL": "AAABBBCCCDDDEEEF"
      }
    }
  }
}

Note: Replace the environment variables with your actual Spruthub server details:

• SPRUTHUB_WS_URL: WebSocket URL of your Spruthub server

• SPRUTHUB_EMAIL: Your Spruthub account email

• SPRUTHUB_PASSWORD: Your Spruthub account password

• SPRUTHUB_SERIAL: Your Spruthub hub serial number

Security Best Practice: For sensitive values like SPRUTHUB_PASSWORD, consider using your system's environment variables instead of hardcoding them in the config file:

{
  "mcpServers": {
    "spruthub-mcp-server": {
      "command": "npx",
      "args": ["spruthub-mcp-server@1.3.9"],
      "env": {
        "SPRUTHUB_WS_URL": "ws://192.168.0.100/spruthub",
        "SPRUTHUB_EMAIL": "your_email@example.com",
        "SPRUTHUB_PASSWORD": "$SPRUTHUB_PASSWORD",
        "SPRUTHUB_SERIAL": "AAABBBCCCDDDEEEF"
      }
    }
  }
}

Then set the password in your system environment:

export SPRUTHUB_PASSWORD="your_actual_password"

Available Tools

This server provides three core tools that give you access to the complete Spruthub JSON-RPC API:

spruthub_list_methods

Discover all available Spruthub API methods with their descriptions and categories.

Parameters:

• category (optional): Filter methods by category (hub, accessory, scenario, room, system)

Example usage: Start here to explore what's available in your Spruthub system.

spruthub_get_method_schema

Get detailed schema information for any API method, including parameters, return types, and examples.

Parameters:

• methodName (required): The method name to get schema for (e.g., accessory.search, characteristic.update)

Important: Always call this tool before using spruthub_call_method to understand the exact parameter structure required.

spruthub_call_method

Execute any Spruthub JSON-RPC API method with the provided parameters.

Parameters:

• methodName (required): The API method to call

• parameters (optional): Method parameters as defined in the method's schema

Critical: You MUST call spruthub_get_method_schema first to understand the parameter structure. Never guess parameters.

Common Workflows

1. Explore your system:

   spruthub_list_methods → spruthub_get_method_schema → spruthub_call_method

2. Control devices:

   spruthub_get_method_schema(methodName: "characteristic.update")
   → spruthub_call_method(methodName: "characteristic.update", parameters: {...})

3. Browse by category:

   spruthub_list_methods(category: "accessory") → Get device-related methods
   spruthub_list_methods(category: "scenario") → Get automation methods

Efficient API Usage

The schema-based approach provides efficient access to Spruthub functionality:

Recommended Workflow

1. Discovery Phase: Use spruthub_list_methods to explore available functionality

2. Schema Phase: Use spruthub_get_method_schema to understand method requirements

3. Execution Phase: Use spruthub_call_method with proper parameters

Best Practices

• Filter by category when exploring: Use category parameter in spruthub_list_methods

• Always get schema first: Never guess API parameters - use spruthub_get_method_schema

• Use specific methods: The API provides targeted methods for efficient operations

• Check method categories:

  • hub - Hub management and status

  • accessory - Device discovery and control

  • scenario - Automation and scenes

  • room - Room management

  • system - System administration

Schema-Driven Development

Each API method includes:

• Complete parameter specifications

• Return type definitions

• Usage examples

• REST API mapping (where available)

• Category classification
