What is HAProxy MCP Server?

HAProxy MCP Server is a bridge service that connects large language models (LLMs) with HAProxy load balancers. It allows users to manage and monitor HAProxy instances through natural language commands without memorizing complex command-line instructions.

How to use HAProxy MCP Server?

After installing the service, simply specify the connection parameters in the LLM configuration to start managing HAProxy through conversations. It supports two connection methods: TCP4 and Unix sockets.

Applicable scenarios

It is suitable for operation and maintenance teams that need to manage HAProxy frequently, non-technical users who want to simplify complex operations, and scenarios where HAProxy management needs to be integrated into automated processes.

Main features

Full runtime API supportFully supports HAProxy runtime API commands, including server status management, configuration query, etc.
Statistics page integrationCan connect to the HAProxy statistics page to obtain visual indicator data
Multi-transport protocol supportSupports two transport methods: stdio and HTTP, adapting to different deployment environments
Dynamic server managementAdd/remove backend servers in real-time and adjust parameters such as weights

Advantages and limitations

Advantages
Natural language interaction lowers the usage threshold
Supports deployment in production environments with enterprise-level reliability
Perfect error handling and timeout mechanism
Provides Docker images to simplify deployment
Limitations
Requires pre-configuring HAProxy to open the management interface
Some advanced functions still require direct use of the HAProxy command line
Performance monitoring depends on the native statistical functions of HAProxy

How to use

Install the service
Choose the installation method suitable for your system: Homebrew, binary package, Go installation, or Docker
Configure connection parameters
Set the HAProxy host address, port, or Unix socket path
Integrate into LLM
Add the MCP server connection information to the LLM configuration
Start using
Manage HAProxy through natural language commands

Usage cases

Monitor server statusCheck the health status and current load of all backend servers
Temporarily maintain nodesTake the specified server offline for maintenance without interrupting the service
