Wazuh MCP Server

Talk to your SIEM. Query alerts, hunt threats, check vulnerabilities, and trigger active responses across your entire Wazuh deployment — through natural conversation with any AI assistant.

What This Does

Your Wazuh SIEM generates thousands of alerts, vulnerability findings, and agent events daily. Investigating them means juggling dashboards, writing API queries, and manually correlating data across tools.

This MCP server turns that workflow into a conversation:

You:    "Show me critical alerts from the last hour"
AI:     [calls get_wazuh_alerts] Found 3 critical alerts:
        1. SSH brute force from 10.0.1.45 → agent-003 (Rule 5712, Level 10)
        2. Rootkit detection on agent-007 (Rule 510, Level 12)
        3. FIM change /etc/shadow on agent-001 (Rule 550, Level 10)

You:    "Block that source IP on agent-003"
AI:     [calls wazuh_block_ip] Blocked 10.0.1.45 via firewall-drop on agent-003.

You:    "Which agents have unpatched critical CVEs?"
AI:     [calls get_critical_vulnerabilities] 3 agents with critical vulnerabilities...

It works with Claude Desktop, Open WebUI + Ollama (fully local, air-gapped), mcphost, or any MCP-compliant client.

Works With Cloud AND Local LLMs

This is a standard MCP tool server. It doesn't care what LLM you use — it just executes tools and returns results.

| Mode | LLM | Client | Data leaves your network? | |------|-----|--------|--------------------------| | Cloud | Claude, GPT, etc. | Claude Desktop, any MCP client | Yes (to LLM provider) | | Local | Llama, Qwen, Mistral via Ollama | Open WebUI, mcphost, IBM/mcp-cli | No. Fully air-gappable. |

For security teams that can't send SIEM data to cloud APIs (compliance, air-gapped networks, data sovereignty), the local mode with Ollama keeps everything on-premises. Both modes coexist — same server, same tools, same API.

Quick Start: Local LLM with mcphost

# 1. Start the MCP server
docker compose up -d

# 2. Install mcphost (Go binary, no dependencies)
go install github.com/mark3labs/mcphost@latest

# 3. Configure
cat > ~/.mcphost.yml << 'EOF'
mcpServers:
  wazuh:
    type: remote
    url: http://localhost:3000/mcp
    headers: ["Authorization: Bearer ${env://MCP_API_KEY}"]
EOF

# 4. Chat with your SIEM using a local model
export MCP_API_KEY="your-key-from-server-logs"
mcphost --model ollama/qwen2.5:7b

Quick Start: Multi-User SOC with Open WebUI

Open WebUI v0.6.31+ connects to our /mcp endpoint natively. Add it as an MCP tool server in Admin Settings, and your entire team gets AI-powered SIEM analysis with conversation history, RBAC, and a web UI.

Quick Start

Prerequisites

• Docker 20.10+ with Compose v2
• Wazuh 4.8.0–4.14.4 with API access enabled

Deploy

git clone https://github.com/gensecaihq/Wazuh-MCP-Server.git
cd Wazuh-MCP-Server
cp .env.example .env

Edit .env:

WAZUH_HOST=your-wazuh-server
WAZUH_USER=your-api-user
WAZUH_PASS=your-api-password

docker compose up -d
curl http://localhost:3000/health

Connect Claude Desktop

1. Settings → Connectors → Add custom connector
2. URL: https://your-server/mcp
3. Add Bearer token in Advanced settings

Detailed setup: Claude Integration Guide

Security

This server sits between an LLM and your SIEM. Security is not optional.

| Layer | What It Does | |-------|-------------| | RBAC | Per-tool scope enforcement. 14 active response tools require wazuh:write. Read-only tokens can query but never trigger actions. Authless mode is read-only by default. | | Audit Logging | Every destructive tool call (block IP, isolate host, kill process) is logged with client ID, session, timestamp, and full arguments. | | Output Sanitization | Credentials, tokens, and API keys in alert full_log fields are redacted before reaching the LLM. Prevents credential leakage through AI responses. | | Input Validation | Every parameter validated: regex agent IDs, ipaddress module for IPs, shell metacharacter blocking for active response, Elasticsearch Query DSL (no string interpolation). | | Rate Limiting | Per-client sliding window with escalating block duration (10s → 5min). | | Circuit Breakers | Wazuh API failures trigger fail-fast for 60s, auto-recover. Single trial in HALF_OPEN state. | | Log Sanitization | Global filter redacts passwords, tokens, secrets from all server logs. | | Container Hardening | Non-root user, read-only filesystem, CAP_DROP ALL, no-new-privileges. |

# Generate a secure API key
python -c "import secrets; print('wazuh_' + secrets.token_urlsafe(32))"

Take It Further: Autonomous Agentic SOC

Combine this MCP server with Wazuh OpenClaw Autopilot to build a fully autonomous Security Operations Center.

While this server gives you conversational access to Wazuh, OpenClaw deploys AI agents that work around the clock — triaging alerts, correlating incidents, and recommending responses without human intervention.

Manual SOC:    Alert → Analyst reviews → Hours → Response
Agentic SOC:   Alert → AI triages → Seconds → Response ready for approval
