GitHub - CorefluxCommunity/Coreflux-MQTT-MCP-Server: Coreflux MQTT MCP Server (original) (raw)

Coreflux MQTT MCP Server

This is a Model Context Protocol (MCP) server that connects to a Coreflux MQTT broker and makes Coreflux and MQTT actions available as tools for Claude and other MCP-compatible AI assistants.

Features

• Connects to Coreflux MQTT broker
• Provides tools for all Coreflux commands (models, actions, rules, routes)
• Discovers and lists available actions
• Includes LOT language documentation as resources
• Built with the official MCP SDK for seamless Claude integration
• Standalone setup assistant for configuration

Setup Assistant

The server includes a standalone setup assistant that can be run separately from the main server. Run the setup assistant when:

• You need to create an initial configuration (.env file)
• You want to update your existing configuration
• You're experiencing connection issues and need to reconfigure

To run the setup assistant:

python setup_assistant.py

The setup assistant helps you:

• Create or update the .env file with your configuration
• Configure MQTT broker settings (host, port, credentials)
• Set up TLS configuration if needed
• Configure logging options

After configuration is complete, you can run the server normally.

Connecting Claude to the MCP Server

Using Claude Desktop Config

1. Create or edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS/Linux) or %USERPROFILE%\AppData\Roaming\Claude\claude_desktop_config.json (Windows)
2. Add the following configuration (adjust the paths accordingly):
   {
   "mcpServers": {
   "coreflux": {
   "command": "python",
   "args": [
   "/PATH/TO/server.py",
   "--mqtt-host", "localhost",
   "--mqtt-port", "1883",
   "--mqtt-user", "root",
   "--mqtt-password", "coreflux",
   "--mqtt-client-id", "claude-coreflux-client"
   ],
   "description": "Coreflux MQTT Broker Control",
   "icon": "🔄",
   "env": {}
   }
   }
   }
3. Restart Claude Desktop

Command-Line Arguments

The server accepts the following command-line arguments. These settings can also be configured via the .env file using the setup assistant:

Debugging and Troubleshooting

If you encounter issues:

1. Verify your MQTT broker credentials in your Claude configuration
2. Ensure the broker is accessible
3. Run the setup assistant to verify or update your configuration:
   python setup_assistant.py
4. Check Claude Desktop logs:

Check Claude's logs for errors (macOS/Linux)

tail -n 20 -f ~/Library/Logs/Claude/mcp*.log

Windows PowerShell

Get-Content -Path "$env:USERPROFILE\AppData\Roaming\Claude\Logs\mcp*.log" -Tail 20 -Wait 5. Run the server with debug logging:

Direct execution with debug logging

python server.py --mqtt-host localhost --mqtt-port 1883 --log-level DEBUG
