MCP Server for Logz.io

An unofficial Model Context Protocol (MCP) server that enables AI assistants like Claude to interact with Logz.io's log management platform. Includes tools for simple log search, Lucene query search, and fetching basic statistics from Logz.io.

🚀 Quick Start

Add this to your Claude/Cursor/etc configuration file:

{
  "mcpServers": {
    
    # other servers ...
    
    "logzio": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-server-logzio", 
        "apiKey", "YOUR_LOGZIO_API_KEY"
      ]
    }
  }
}

US is the default region. For other regions:

{
  "mcpServers": {
    
    # other servers ...
    
    "logzio": {
      "command": "npx", 
      "args": [
        "-y",
        "mcp-server-logzio",
        "apiKey", "YOUR_LOGZIO_API_KEY",
        "region", "eu" # add this for example
      ]
    }
  }
}

🛠️ Advanced Configuration

Command Line Arguments

Supported Regions

The server automatically maps region codes to the correct Logz.io API endpoints:

Finding Your Region: Log into your Logz.io account and check the URL in your browser:

• https://app.logz.io → use region us
• https://app-eu.logz.io → use region eu
• https://app-ca.logz.io → use region ca
• etc.
