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.
v4.2.1 | 54 security tools | Wazuh 4.8.0–4.14.4 | Changelog
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_wazuh_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.
54 Security Tools
Every tool is validated, rate-limited, scope-checked, and audit-logged.

| Active Response (9) | wazuh_block_ip wazuh_isolate_host wazuh_kill_process wazuh_disable_user wazuh_quarantine_file wazuh_firewall_drop wazuh_host_deny wazuh_active_response wazuh_restart |
Block IPs, isolate hosts, kill processes, quarantine files |
| Verification (5) | wazuh_check_blocked_ip wazuh_check_agent_isolation wazuh_check_process wazuh_check_user_status wazuh_check_file_quarantine |
Verify active response actions took effect |
| Rollback (5) | wazuh_unisolate_host wazuh_enable_user wazuh_restore_file wazuh_firewall_allow wazuh_host_allow |
Undo active response actions |
The 14 state-changing tools (Active Response + Rollback) require the wazuh:write scope; everything else needs only wazuh:read. ISO 27001 also adds an iso27001_assessment guided prompt (5 prompts total).

Security
This server sits between an LLM and your SIEM. Security is not optional.
| Layer | What It Does |
|---|---|
| RBAC | Per-tool scope enforcement, fail-closed: a token with no scope claim gets read-only, never write. The 14 state-changing tools (active response + rollback) require wazuh:write, which is opt-in (MCP_API_KEY_SCOPES="wazuh:read wazuh:write"). Authless mode is read-only unless AUTHLESS_ALLOW_WRITE=true. |
| 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))"
