nagios-mcp

![](https://badge.mcpx.dev?type=server 'MCP Server') PyPI - Version Python Version from PEP 621 TOML

MCP Server for Nagios Core.

This server is built by us for the Nagios Core web-client. The code for the server can be found here. The server utilizes the CGI binaries located at the cgi-bin or sbin folder in your Nagios folder. More specifically the statusjson.cgi and objectjson.cgi files for the purpose of the status and configuration tooling.

How to install:

Setting up

Installing the PyPI package

# Using pip
pip install nagios-mcp # or pipx install nagios-mcp

# Using uv (Recommended)
uv tool install nagios-mcp

Creating a config file

Create a nagios_config.yaml or nagios_config.json file with the configuration parameters given below.

nagios_url: "http://localhost/nagios"
nagios_user: "your_nagios_core_username"
nagios_pass: "your_nagios_core_password"
ca_cert_path: "path_to_your_ssl_cert" # if the url is https, otherwise leave it empty ("")

Starting the SSE server

The mcp server by default runs on STDIO transport. If you do not require SSE transport, you can skip this section.
Command: uvx nagios-mcp --config NAGIOS_CONFIG_FILE --transport sse --host localhost --port 8000

For Claude Desktop

Official setup guide
For setting up in Claude Desktop, go to Settings -> Developer -> Edit Config. Or directly modify the config file,
MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Add the following block to the config file,

{
  "mcpServers": {
    "nagios": {
      "command": "uvx",
      "args": [
        "nagios-mcp",
        "--config",
        "PATH_TO_THE_NAGIOS_CONFIG_FILE",
      ],
    },
  },
}

For SSE transport:

{
    "mcpServers": {
        "nagios": {
            "url": "http://localhost:8000/sse" # change this if you are using different port
        }
    }
}

For Cursor

Official setup guide
To setup the server in Cursor, go to Setting -> MCP -> Add new global MCP server, and add the following:

For STDIO transport:

{
  "mcpServers": {
    "nagios": {
        "command": "uvx",
        "args": [
                "nagios-mcp",
                "--config", "PATH_TO_THE_NAGIOS_CONFIG_FILE"
            ],
        }
    }
}

For SSE Transport:

{
    "mcpServers": {
        "nagios": {
            "url": "http://localhost:8000/sse" # change this if you are using different port
        }
    }
}

For Windsurf

Official setup guide
For setting up the server in Windsurf, add the following lines to the ~/.codeium/windsurf/mcp_config.json file.

{
    "mcpServers": {
        "nagios": {
            "command": "uvx",
            "args": [
                "nagios-mcp",
                "--config", "PATH_TO_THE_NAGIOS_CONFIG_FILE"
            ],
        }
    }
}

For SSE Transport:

{
    "mcpServers": {
        "nagios": {
            "serverUrl": "http://localhost:8000/sse" # change this if you are using different port
        }
    }
}

For Cline

Official setup guide
For setting up the server in Cline, go to MCP Servers -> Installed -> Configure MCP Servers, this will open the cline_mcp_settings.json file. Add the following code block to the file.

{
    "mcpServers": {
        "nagios": {
            "command": "uvx",
            "args": [
                "nagios-mcp",
                "--config", "PATH_TO_THE_NAGIOS_CONFIG_FILE"
            ],
        }
    }
}

For SSE Transport:

{
    "mcpServers": {
        "nagios": {
            "url": "http://localhost:8000/sse" # change this if you are using different port
        }
    }
}

For 5ire

5ire is another MCP client. For setting up in 5ire, go to Tools -> New and add the following configuration.

Tool Key: Nagios
Name: NagiosMCP

Currently all the tools use GET requests. Other useful tools and tools requiring POST requests will be added soon.

How the MCP server works?

Nagios Core web-client is typically hosted on http://YOUR_HOST/nagios/
The MCP server reads the details about the processes and services using the CGI binaries, they can be found in the cgi-bin or sbin sub-directory in your Nagios main directory.
The Status Tools and Config Tools use the cgi-bin/statusjson.cgi and cgi-bin/objectjson.cgi files respectively for retrieving the information.
