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.

*I'll be a little surprised if logz io makes an official MCP server. Instead, they seem to be leaning heavily into integrating AI directly into their tooling, which makes sense, but doesn't give the user much flexibility over models or integration with external tools.. which is why this project exists.

🚀 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

Argument	Description	Default	Required
apiKey <key>	Your Logz.io API key	-	Yes
region <region>	Logz.io region (us, us-west, eu, ca, au, uk)	us	No
logzioUrl <url>	Custom Logz.io API URL (overrides region)	-	No
--timeout <ms>	Request timeout	30000	No
--retry-attempts <num>	Retry attempts	3	No
--max-results <num>	Max results per query	1000	No

Supported Regions

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

Region Code	Description	API Endpoint
us	US East (default)	https://api.logz.io
us-west	US West	https://api-wa.logz.io
eu	Europe	https://api-eu.logz.io
ca	Canada	https://api-ca.logz.io
au	Australia	https://api-au.logz.io
uk	United Kingdom	https://api-uk.logz.io

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.
