Описание

An MCP server for the Wazuh SIEM/XDR platform that enables users to query agents, security alerts, detection rules, and decoders through Claude or other MCP clients. It provides specialized tools and prompts for investigating security alerts, performing agent health checks, and generating environmental security overviews.

README

TypeScript Node.js MCP License: MIT

A Model Context Protocol (MCP) server for the Wazuh SIEM/XDR platform. Query agents, security alerts, detection rules, and decoders directly from Claude or any MCP-compatible client.

Features

25 MCP Tools - Agents, alerts, rules, decoders, SCA, syscollector, FIM, rootcheck, groups, and manager
3 MCP Resources - Pre-built views for agents, recent alerts, and rule summaries
3 MCP Prompts - Alert investigation, agent health checks, and security overviews
JWT Authentication - Automatic token management with refresh on expiry
Full Compliance Mapping - PCI-DSS, GDPR, HIPAA, NIST 800-53, MITRE ATT&CK
Pagination - All list endpoints support limit/offset pagination
Type-Safe - Full TypeScript with strict mode and Zod schema validation

Prerequisites

Node.js 20+
A running Wazuh manager with API access (default port 55000)
Wazuh API credentials (username/password)
(Optional) Wazuh Indexer (OpenSearch) access for alert queries

Installation

git clone https://github.com/solomonneas/wazuh-mcp.git
cd wazuh-mcp
npm install
npm run build

Configuration

Set the following environment variables:

Variable	Required	Default	Description
`WAZUH_URL`	Yes	-	Wazuh API URL (e.g., `https://10.0.0.2:55000`)
`WAZUH_USERNAME`	Yes	-	API username
`WAZUH_PASSWORD`	Yes	-	API password
`WAZUH_VERIFY_SSL`	No	`false`	Set to `true` to verify SSL certificates

Alternative variable names WAZUH_BASE_URL and WAZUH_USER are also supported.

Wazuh Indexer (OpenSearch) - Required for Alerts

Wazuh 4.x stores alerts in the Wazuh Indexer (OpenSearch), not the REST API. To enable alert tools (get_alerts, get_alert, search_alerts) and the wazuh://alerts/recent resource, configure the indexer connection:

Variable	Required	Default	Description
`WAZUH_INDEXER_URL`	No	-	Wazuh Indexer URL (e.g., `https://10.0.0.2:9200`)
`WAZUH_INDEXER_USERNAME`	No	`admin`	Indexer username
`WAZUH_INDEXER_PASSWORD`	No	-	Indexer password
`WAZUH_INDEXER_VERIFY_SSL`	No	`false`	Set to `true` to verify SSL certificates

If WAZUH_INDEXER_URL is not set, alert tools will return a helpful configuration message. All other tools (agents, rules, decoders, version) work without the indexer.

Usage

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "wazuh": {
      "command": "wazuh-mcp",
      "env": {
        "WAZUH_URL": "https://your-wazuh-manager:55000",
        "WAZUH_USERNAME": "wazuh-wui",
        "WAZUH_PASSWORD": "your-password",
        "WAZUH_INDEXER_URL": "https://your-wazuh-indexer:9200",
        "WAZUH_INDEXER_USERNAME": "admin",
        "WAZUH_INDEXER_PASSWORD": "your-indexer-password"
      }
    }
  }
}

Claude Code

claude mcp add wazuh \
  --env WAZUH_URL=https://your-wazuh-manager:55000 \
  --env WAZUH_USERNAME=wazuh-wui \
  --env WAZUH_PASSWORD=your-password \
  --env WAZUH_INDEXER_URL=https://your-wazuh-indexer:9200 \
  --env WAZUH_INDEXER_USERNAME=admin \
  --env WAZUH_INDEXER_PASSWORD=your-indexer-password \
  -- wazuh-mcp

Add --scope user to make it available from any directory instead of only the current project.

OpenClaw

If you're running from a source checkout instead of the npm-installed binary, point command/args at the built dist/index.js:

openclaw mcp set wazuh '{
  "command": "node",
  "args": ["/absolute/path/to/wazuh-mcp/dist/index.js"],
  "env": {
    "WAZUH_URL": "https://your-wazuh-manager:55000",
    "WAZUH_USERNAME": "wazuh-wui",
    "WAZUH_PASSWORD": "your-password",
    "WAZUH_INDEXER_URL": "https://your-wazuh-indexer:9200",
    "WAZUH_INDEXER_USERNAME": "admin",
    "WAZUH_INDEXER_PASSWORD": "your-indexer-password"
  }
}'

Or, with the global npm install:

openclaw mcp set wazuh '{
  "command": "wazuh-mcp",
  "env": {
    "WAZUH_URL": "https://your-wazuh-manager:55000",
    "WAZUH_USERNAME": "wazuh-wui",
    "WAZUH_PASSWORD": "your-password",
    "WAZUH_INDEXER_URL": "https://your-wazuh-indexer:9200",
    "WAZUH_INDEXER_USERNAME": "admin",
    "WAZUH_INDEXER_PASSWORD": "your-indexer-password"
  }
}'

Then restart the OpenClaw gateway so the new server is picked up:

systemctl --user restart openclaw-gateway
openclaw mcp list   # confirm "wazuh" is registered

Hermes Agent

Hermes Agent reads MCP config from ~/.hermes/config.yaml under the mcp_servers key. Add an entry:

mcp_servers:
  wazuh:
    command: "wazuh-mcp"
    env:
      WAZUH_URL: "https://your-wazuh-manager:55000"
      WAZUH_USERNAME: "wazuh-wui"
      WAZUH_PASSWORD: "your-password"
      WAZUH_INDEXER_URL: "https://your-wazuh-indexer:9200"
      WAZUH_INDEXER_USERNAME: "admin"
      WAZUH_INDEXER_PASSWORD: "your-indexer-password"

Or, when running from a source checkout instead of the global npm install:

mcp_servers:
  wazuh:
    command: "node"
    args: ["/absolute/path/to/wazuh-mcp/dist/index.js"]
    env:
      WAZUH_URL: "https://your-wazuh-manager:55000"
      WAZUH_USERNAME: "wazuh-wui"
      WAZUH_PASSWORD: "your-password"
      WAZUH_INDEXER_URL: "https://your-wazuh-indexer:9200"
      WAZUH_INDEXER_USERNAME: "admin"
      WAZUH_INDEXER_PASSWORD: "your-indexer-password"

Then reload MCP from inside a Hermes session:

/reload-mcp

Codex CLI

Codex CLI registers MCP servers via codex mcp add:

codex mcp add wazuh \
  --env WAZUH_URL=https://your-wazuh-manager:55000 \
  --env WAZUH_USERNAME=wazuh-wui \
  --env WAZUH_PASSWORD=your-password \
  --env WAZUH_INDEXER_URL=https://your-wazuh-indexer:9200 \
  --env WAZUH_INDEXER_USERNAME=admin \
  --env WAZUH_INDEXER_PASSWORD=your-indexer-password \
  -- wazuh-mcp

Or, when running from a source checkout:

codex mcp add wazuh \
  --env WAZUH_URL=https://your-wazuh-manager:55000 \
  --env WAZUH_USERNAME=wazuh-wui \
  --env WAZUH_PASSWORD=your-password \
  -- node /absolute/path/to/wazuh-mcp/dist/index.js

Codex writes the entry to ~/.codex/config.toml under [mcp_servers.wazuh]. Verify with:

codex mcp list

Standalone

export WAZUH_URL=https://your-wazuh-manager:55000
export WAZUH_USERNAME=wazuh-wui
export WAZUH_PASSWORD=your-password
npm start
