What is Corefluxmcpserver

CorefluxMCPServer is a Model Context Protocol (MCP) server that connects to a Coreflux MQTT broker, enabling Coreflux actions to be utilized as tools for Claude and other MCP-compatible AI assistants.

Use cases

Use cases for CorefluxMCPServer include automating tasks with AI assistants, managing IoT devices through MQTT, and enhancing AI capabilities by providing access to Coreflux actions and commands.

How to use

To use CorefluxMCPServer, run the standalone setup assistant to configure your environment, including MQTT broker settings. After configuration, connect Claude to the MCP server by editing the appropriate configuration file and specifying the server details.

Key features

Key features of CorefluxMCPServer include connection to the Coreflux MQTT broker, availability of tools for all Coreflux commands, action discovery and listing, LOT language documentation, seamless integration with Claude using the official MCP SDK, and a standalone setup assistant for configuration.

Where to use

CorefluxMCPServer can be used in various fields where AI assistants are implemented, particularly in environments that utilize MQTT for communication and require integration with Coreflux actions.

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:

Argument	Description	Default
--mqtt-host	MQTT broker address	localhost
--mqtt-port	MQTT broker port	1883
--mqtt-user	MQTT username	-
--mqtt-password	MQTT password	-
--mqtt-client-id	MQTT client ID	claude-mcp-client
--mqtt-use-tls	Enable TLS for MQTT connection	false
--mqtt-ca-cert	Path to CA certificate file	-
--mqtt-client-cert	Path to client certificate file	-
--mqtt-client-key	Path to client key file	-
--log-level	Logging level (DEBUG/INFO/WARNING/ERROR/CRITICAL)	INFO

Available Tools

The server provides tools for common Coreflux commands:

• add_rule: Add a new permission rule
• remove_rule: Remove a permission rule
• add_route: Add a new route connection
• remove_route: Remove a route connection
• add_model: Add a new model structure
• remove_model: Remove a model structure
• add_action: Add a new action event/function
• remove_action: Remove an action event/function
• run_action: Run an action event/function
• remove_all_models: Remove all models
• remove_all_actions: Remove all actions
• remove_all_routes: Remove all routes
• list_discovered_actions: List all discovered Coreflux actions

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
