Azure Log Analytics MCP Server

An MCP (Model Context Protocol) server for querying Azure Log Analytics using natural language. This server allows large language models to convert natural language queries into KQL (Kusto Query Language) and execute them against Azure Log Analytics.

Features

• Convert natural language queries to KQL using Claude AI
• Execute KQL queries against Azure Log Analytics
• Format results for easy consumption by LLMs
• CLI mode for direct interactions and MCP server mode for LLM integrations

Prerequisites

• Node.js 18.x or higher
• An Azure subscription with Log Analytics workspace
• An Anthropic API key for Claude AI
• Azure CLI configured with appropriate credentials

Installation

# Clone the repository
git clone https://github.com/MananShahTR/azure-log-analytics-mcp.git
cd azure-log-analytics-mcp

# Install dependencies

      "env": {
        "ANTHROPIC_API_KEY": "your_key_here"
      }
    }
  }
}
