Domotz MCP Server

License Node.js

A Model Context Protocol (MCP) server for Domotz network monitoring and management. Enables AI assistants to monitor network devices, view alerts, check device status, and manage network infrastructure.

This is a Model Context Protocol (MCP) server that connects Claude (or any MCP-compatible AI) to your Domotz environment.

Part of the MSP Claude Plugins ecosystem — a growing suite of AI integrations for the MSP stack. Built by MSPs, for MSPs.

Installation

npm install @wyre-ai/domotz-mcp

Related MCP server: network-mcp-server

Configuration

Copy .env.example and set the variables below.

Variable

Required

Description

DOMOTZ_API_KEY

For stdio and AUTH_MODE=env

Domotz Public API key

DOMOTZ_REGION

No

API region cell label (default: us-east-1)

MCP_TRANSPORT

No

stdio (default) or http

AUTH_MODE

No

gateway (Docker image and Compose default) or env. Gateway mode requires X-Domotz-API-Key on each /mcp request and never falls back to DOMOTZ_API_KEY. env uses that variable only after S2S auth succeeds.

CONDUIT_S2S_SECRET

Yes for HTTP

Service-to-service secret. The HTTP server logs an error and exits non-zero when this is empty or a known placeholder (changeme, secret, your-s2s-secret, replace-with-a-real-secret, and the other values rejected in src/http.ts). Compose will not start without it. Never commit a real value. The value is never logged.

MCP_ALLOW_INSECURE_DEV

No

Set to exactly 1 only for local development to start HTTP without CONDUIT_S2S_SECRET. The process logs a warning, does not enforce X-Gateway-S2S, and binds 127.0.0.1 only. A non-loopback MCP_HTTP_HOST is ignored and the override is logged. A known placeholder secret is still refused.

MCP_HTTP_HOST

No

Bind address when MCP_TRANSPORT=http. Defaults to 127.0.0.1. Honored when CONDUIT_S2S_SECRET is set. The container image sets 0.0.0.0.

MCP_HTTP_PORT

No

HTTP port. Defaults to 8080.

/health stays unauthenticated and does not read credentials. The stdio transport does not use CONDUIT_S2S_SECRET.

HTTP authentication

With MCP_TRANSPORT=http and CONDUIT_S2S_SECRET set, every /mcp request must include X-Gateway-S2S. The check is verifyS2sHeader in src/s2s-verify.ts: the header value is t=<unix seconds>,v1=<hex>, where the hex is HMAC-SHA256 of the literal string t=<unix seconds> keyed with CONDUIT_S2S_SECRET (64 lowercase hex characters). The timestamp must be within 300 seconds of the server clock. A missing or invalid header returns 401 before vendor credentials are read.

TS=$(date +%s)
SIG=$(printf 't=%s' "$TS" | openssl dgst -sha256 -hmac "$CONDUIT_S2S_SECRET" -hex | awk '{print $NF}')
curl -sS http://127.0.0.1:8080/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -H "X-Gateway-S2S: t=${TS},v1=${SIG}" \
  -H "X-Domotz-API-Key: $DOMOTZ_API_KEY" \
  -H 'X-Domotz-Region: us-east-1' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

In AUTH_MODE=gateway, /mcp also requires X-Domotz-API-Key (X-Domotz-Region is optional and defaults to us-east-1). That header is the only credential source for the request. In AUTH_MODE=env, a valid X-Gateway-S2S header is still required and vendor credentials come from DOMOTZ_API_KEY.

Usage

Running with Claude Desktop

Add to your Claude Desktop claude_desktop_config.json:

{
  "mcpServers": {
    "domotz-mcp": {
      "command": "npx",
      "args": ["@wyre-ai/domotz-mcp"],
      "env": {
        "DOMOTZ_API_KEY": "your-domotz-api-key"
      }
    }
  }
}

Running with Claude Code (CLI)

claude mcp add domotz-mcp \
  -e DOMOTZ_API_KEY=your-value \
  -- npx -y @wyre-ai/domotz-mcp

Docker

The image listens on 0.0.0.0 inside the container (MCP_HTTP_HOST) and defaults to AUTH_MODE=gateway. Publish the port on loopback and pass the S2S secret. In gateway mode, the Domotz API key arrives on each request as X-Domotz-API-Key; it is not read from the environment. Compose does not set DOMOTZ_API_KEY.

docker build -t domotz-mcp .
docker run \
  -e CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" \
  -p 127.0.0.1:8080:8080 \
  domotz-mcp

Compose refuses to start when CONDUIT_S2S_SECRET is unset, sets AUTH_MODE=gateway, and publishes 127.0.0.1:8080:8080. Generate the secret with openssl rand -hex 32; do not use a placeholder such as your-s2s-secret.

CONDUIT_S2S_SECRET="$(openssl rand -hex 32)" docker compose up

Single-tenant HTTP (AUTH_MODE=env) still requires the S2S secret, then uses DOMOTZ_API_KEY:

docker run \
  -e CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" \
  -e AUTH_MODE=env \
  -e DOMOTZ_API_KEY=your-value \
  -e DOMOTZ_REGION=us-east-1 \
  -p 127.0.0.1:8080:8080 \
  domotz-mcp

Local HTTP without a secret is development-only. It binds 127.0.0.1 only and logs a warning. A non-loopback MCP_HTTP_HOST, including 0.0.0.0, is ignored:

MCP_TRANSPORT=http MCP_ALLOW_INSECURE_DEV=1 npm run start:http

Available Tools

2 tools
domotz_navigateA

Navigate to a domain to access Domotz tools. Domains: agents (collectors/sites), devices (network devices), metrics (SNMP/variables), network (topology/interfaces), alerts (alert profiles), power (PDU/outlets).

NameRequiredDescriptionDefault
domainYesThe domain to navigate to

TDQS

A3.8/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must bear full burden. It only says 'navigate to a domain to access tools' without disclosing behavioral traits like side effects, authentication needs, or what happens after navigation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences: first states purpose, second lists domains. No wasted words, front-loaded with key information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given only one parameter with full schema coverage and no output schema, the description provides sufficient context for a navigation tool. Could mention expected return or effect, but minimalism is acceptable.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has 100% coverage with an enum and description. The description adds value by mapping each domain to underlying tools (e.g., 'agents (collectors/sites)'), providing context beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Navigate to a domain to access Domotz tools' with a specific verb and resource, and lists all possible domains, distinguishing it from the sibling tool 'domotz_status' which likely checks status.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage (when you want to access a specific domain) but does not explicitly state when to use it vs. the sibling tool or any exclusions/alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

domotz_statusA

Check Domotz API connection status and available domains.

NameRequiredDescriptionDefault

No parameters

TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden. It indicates a read-only check operation, which is appropriate, but lacks details on backend calls, authentication, or performance implications.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, no extraneous words. Perfectly concise for a simple tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a parameterless tool with no output schema, the description covers the essential purpose. However, it omits details about the response format or what 'available domains' means, which could be slightly improved.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are zero parameters, so the description adds no parameter meaning. Baseline is 4 because no parameter documentation is needed.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Check') and clearly specifies the resource ('Domotz API connection status and available domains'). It distinguishes itself from the sibling 'domotz_navigate' tool by focusing on status rather than navigation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage when needing to verify connectivity or list domains, but provides no explicit guidance on when to avoid this tool or compare with siblings like 'domotz_navigate'.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Scored across 2 tools

Disambiguation5/5

The two tools have completely distinct purposes: one navigates to various domains, the other checks API status. No overlap or ambiguity.

Naming Consistency5/5

Both tools follow the same 'domotz_verb' pattern with simple, clear verbs: 'navigate' and 'status'. Consistent and predictable.

Tool Count2/5

With only 2 tools covering a wide range of domains (agents, devices, metrics, network, alerts, power), the tool surface is too thin for the apparent scope. Likely requires heavy parameterization in a single tool.

Completeness2/5

The server only provides navigation to domains and status check, but no actual CRUD or action tools for those domains. This is severely incomplete for practical management tasks.
