Wazuh Mcp

wazuh-mcp

An MCP server that lets an AI client query your Wazuh SIEM/XDR: alerts, agents, vulnerabilities, rules, and more, read-only.

Website: lidless.dev/wazuh-mcp

wazuh-mcp is a Model Context Protocol (MCP) server for the Wazuh SIEM/XDR platform. It exposes your Wazuh manager and Wazuh Indexer as MCP tools so Claude, Claude Code, or any MCP-compatible client can investigate alerts, triage agents, and pull vulnerability inventory in plain language. It is read-only by design and security-first: TLS verification is on by default, sensitive fields (agent IPs, full logs, file hashes, command lines) are hidden unless you opt in per call, and attacker-controlled SIEM text is wrapped in untrusted-data markers to blunt prompt injection against the calling model.

What it does

wazuh-mcp turns a Wazuh SIEM/XDR deployment into a set of MCP tools an AI agent can call. Point your MCP client at the server, give it your Wazuh manager and (optionally) Wazuh Indexer credentials, and the model can list active and disconnected agents, retrieve and full-text search security alerts, pull vulnerability inventory by CVE or severity, inspect detection rules and decoders, review SCA (Security Configuration Assessment) results, walk system inventory (OS, packages, processes, ports, network, hotfixes), read File Integrity Monitoring and rootcheck findings, fetch manager logs and configuration, and run a connection diagnostic. It ships 28 tools, 3 resources, and 3 guided prompts over stdio. The server only ever reads from Wazuh: the sole writes it performs are JWT authentication against the manager and _search queries against the indexer.

Installation

The quickstart below runs the published npm package with npx, which is the recommended path. To work from source instead:

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

Quickstart

Run it straight from npm with npx, no clone or build required:

{
  "mcpServers": {
    "wazuh": {
      "command": "npx",
      "args": ["-y", "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"
      }
    }
  }
}

Drop that into your MCP client's server config (see [Usage](#usage) for the exact file per client), restart the client, and ask it something like "list the active Wazuh agents" or "search alerts for brute force in the last 24 hours." The indexer settings are optional: without them the agent, rule, decoder, and version tools still work, and the alert and vulnerability tools return a configuration message instead of failing.

Prefer a global install?

npm install -g wazuh-mcp
# then use "command": "wazuh-mcp" instead of the npx invocation above

Usage

The quickstart mcpServers block at the top works for most clients. The per-client recipes below give you the exact file location or CLI command for each.

Claude Desktop

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

{
  "mcpServers": {
    "wazuh": {
      "command": "npx",
      "args": ["-y", "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 \
  -- npx -y wazuh-mcp

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

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 \
  -- npx -y wazuh-mcp

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

OpenClaw

With the npm package:

openclaw mcp set wazuh '{
  "command": "npx",
  "args": ["-y", "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, 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"
  }
}'

Then restart the 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: "npx"
    args: ["-y", "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 reload MCP from inside a Hermes session with /reload-mcp.

Standalone

export WAZUH_URL=https://your-wazuh-manager:55000
export WAZUH_USERNAME=wazuh-wui
export WAZUH_PASSWORD=your-password
npx -y wazuh-mcp

Configuration

Set the following environment variables:

| Variable | Required | Default | Description | |----------|----------|---------|-------------| | WAZUH_URL | Yes | - | Wazuh API URL (e.g., https://192.0.2.2:55000) | | WAZUH_USERNAME | Yes | - | API username | | WAZUH_PASSWORD | Yes | - | API password | | WAZUH_VERIFY_SSL | No | true | Verifies SSL certificates by default. Set to false (also accepts 0/no/off) to disable verification for trusted self-signed lab environments only. | | WAZUH_TIMEOUT | No | 30 | Request timeout in seconds. Must be a positive integer. | | WAZUH_ALLOW_SENSITIVE_CONFIG | No | false | Server-side gate for get_manager_config. When unset/false, sensitive configuration values are always redacted even if the tool's include_sensitive_config argument is true. Set to true (also accepts 1/yes/on) to allow unredacted output when explicitly requested. | | WAZUH_MCP_MAX_RESPONSE_BYTES | No | 250000 | Maximum MCP tool response size before returning a truncated preview with metadata. |

Alternative variable names WAZUH_BASE_URL and WAZUH_USER are also supported.

Wazuh Indexer (OpenSearch) - Required for Alerts and Vulnerabilities

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

| Variable | Required | Default | Description | |----------|----------|---------|-------------| | WAZUH_INDEXER_URL | No | - | Wazuh Indexer URL (e.g., https://192.0.2.2:9200) | | WAZUH_INDEXER_USERNAME | No | admin | Indexer username | | WAZUH_INDEXER_PASSWORD | Yes, when WAZUH_INDEXER_URL is set | - | Indexer password. The server fails fast at startup if WAZUH_INDEXER_URL is set without it. | | WAZUH_INDEXER_VERIFY_SSL | No | true | Verifies SSL certificates by default. Set to false (also accepts 0/no/off) to disable verification for trusted self-signed lab environments only. | | WAZUH_INDEXER_TIMEOUT | No | 30 | Indexer request timeout in seconds. Must be a positive integer. |

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

SSL certificate verification is enabled by default (secure by default). When either SSL verification setting is explicitly set to false, the server prints a startup warning to stderr. TLS verification is disabled only for that configured Wazuh client.

Sensitive Output Defaults

Several tools return minimized output by default to avoid exposing raw logs, IPs, command lines, hashes, or raw event payloads unless requested:

| Tool | Hidden by default | Opt-in field | |------|-------------------|--------------| | list_agents, get_agent, get_group_agents | Agent IP details | include_ip: true | | get_alerts, search_alerts | full_log | include_full_log: true | | get_alert | full_log, raw data | include_full_log: true, include_raw_data: true | | list_vulnerabilities, search_vulnerabilities | Vulnerability descriptions | include_description: true | | get_agent_processes | Process command lines and arguments | include_command: true | | get_fim_files | MD5 and SHA-256 hashes | include_hashes: true | | get_manager_logs | Full log descriptions | include_description: true | | get_manager_config | Secret-like config values | include_sensitive_config: true (only honored when the server-side WAZUH_ALLOW_SENSITIVE_CONFIG flag is enabled; otherwise always redacted) |

Untrusted SIEM Content

Alert and log fields originate on monitored endpoints: anyone who can write a log line to a monitored host (a failed SSH login with a crafted username, a web request path, a syslog message) controls the text that lands in full_log, alert rule_description, raw event data, and manager log descriptions. To blunt prompt injection against the calling agent, the server wraps those values in ... markers, includes an output.untrusted_data_note warning in affected responses, and states in the tool descriptions that the content is attacker-influenced data, never instructions to follow.

Input Validation

Tool inputs are validated before requests are sent to Wazuh. Pagination is bounded, search text is length-limited, sort fields are enumerated per tool, and path-oriented identifiers such as agent IDs, alert IDs, group IDs, and SCA policy IDs reject unsupported characters.

Paginated tool responses include a pagination object with total, limit, offset, and has_more fields while preserving the existing top-level total, limit, and offset fields.

Tool responses are capped by WAZUH_MCP_MAX_RESPONSE_BYTES. Oversized responses return valid JSON with output.response_truncated, byte counts, and a preview instead of flooding the MCP client.

Transient manager GET requests and indexer search/readiness requests retry briefly on 429, 502, 503, 504, and common transient network reset or timeout errors.
