Wazuh MCP Server

A production-grade, open-source MCP server for integrating Wazuh security data with LLMs (such as the Claude Desktop App). This service authenticates with the Wazuh RESTful API, retrieves alerts from Elasticsearch indices, transforms events into an MCP-compliant JSON format, and exposes an HTTP endpoint for Claude Desktop to fetch real-time security context.

Features

JWT-Based Authentication: Securely authenticate with Wazuh using JWT tokens.
Alert Retrieval: Query Elasticsearch indices for Wazuh alert data.
MCP Message Transformation: Convert security events into standardized MCP messages.
Flask HTTP Server: Exposes an /mcp endpoint for Claude Desktop integration.
Robust Error Handling: Handles token expiration, network timeouts, and malformed data.
Configurable: Easily configure via environment variables and integrate with Claude Desktop via its config file.

Prerequisites

Python 3.8+
Access to a Wazuh API instance.
(Optional) Claude Desktop configured to call the MCP server.

Installation

Clone the Repository:
git clone https://github.com/unmuktoai/Wazuh-MCP-Server.git cd Wazuh-MCP-Server

Create and Activate a Virtual Environment:

python3 -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate

Install Dependencies:

pip install -r requirements.txt

Configuration Set the following environment variables to configure the MCP server:

WAZUH_HOST: Wazuh server hostname or IP. WAZUH_PORT: Port for the Wazuh API (default: 55000). WAZUH_USER: Wazuh API username. WAZUH_PASS: Wazuh API password. VERIFY_SSL: Set to "true" or "false" (default: false). MCP_SERVER_PORT: Port on which the MCP server will run (default: 8000).

Example (MacOS):

export WAZUH_HOST="your_wazuh_server" export WAZUH_PORT="55000" export WAZUH_USER="your_username" export WAZUH_PASS="your_password" export VERIFY_SSL="false" export MCP_SERVER_PORT="8000"

Running the Server Start the MCP server with:

python wazuh_mcp_server.py

The server will listen on all interfaces at the port specified by

MCP_SERVER_PORT.

Integration with Claude Desktop To integrate with Claude Desktop, update its configuration file:

MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%/Claude/claude_desktop_config.json Add the following entry under mcpServers:

{ "mcpServers": { "mcp-server-wazuh": { "command": "python3 /path/to/Wazuh-MCP-Server/wazuh_mcp_server.py", "env": { "WAZUH_HOST": "your_wazuh_server", "WAZUH_PORT": "55000", "WAZUH_USER": "your_username", "WAZUH_PASS": "your_password", "MCP_SERVER_PORT": "8000", "VERIFY_SSL": "false" } } } }
