lordraw/watchyourlan-mcp repository overview

⁠watchyourlan-mcp

MCP server for WatchYourLAN⁠ — exposes your network monitoring instance as tools that any MCP-compatible client (Claude Desktop, Claude Code, custom agents) can call.

Source: github.com/lordraw77/watchyourlan-mcp⁠

⁠What's inside

The image ships two Python scripts:

File	Role
`server.py`	MCP server — 10 tools, stdio and SSE transports
`agent.py`	Interactive CLI agent powered by OpenRouter

The active mode is selected by environment variables passed to docker run.

⁠Architecture

MODE 1 — MCP server, stdio  (default CMD)
──────────────────────────────────────────────────────────
MCP client (Claude Desktop / SDK)
      │  stdin / stdout  (JSON-RPC 2.0)
      ▼
[ lordraw/watchyourlan-mcp ]
      │  HTTP
      ▼
WatchYourLAN  :8840


MODE 2 — MCP server, SSE  (MCP_TRANSPORT=sse)
──────────────────────────────────────────────────────────
MCP client (Claude Desktop / Code / SDK)
      │  HTTP  GET /sse
      ▼
[ lordraw/watchyourlan-mcp  :8080 ]
      │  HTTP
      ▼
WatchYourLAN  :8840


MODE 3 — interactive agent  (override CMD to agent.py)
──────────────────────────────────────────────────────────
terminal
      │  stdin / stdout
      ▼
[ lordraw/watchyourlan-mcp  →  agent.py ]
      │  stdio subprocess          │  HTTPS
      ▼                            ▼
[ server.py ]               OpenRouter LLM
      │  HTTP
      ▼
WatchYourLAN  :8840

⁠Image details

Property	Value
Base image	`python:3.12-slim`
Build	Multi-stage — deps compiled in builder layer, only runtime ships
Default transport	`stdio`
SSE port	`8080`
Default command	`python3.12 server.py`
Config	Environment variables (`--env-file .env`)

⁠Quick start

⁠Mode 1 — stdio MCP server

docker run --rm -i \
  --env-file .env \
  lordraw/watchyourlan-mcp

The -i flag is required — the stdio transport keeps stdin open.

⁠Mode 2 — SSE MCP server

docker run --rm \
  --env-file .env \
  -e MCP_TRANSPORT=sse \
  -p 8080:8080 \
  lordraw/watchyourlan-mcp

MCP clients connect to http://localhost:8080/sse.

⁠Mode 3 — interactive agent

docker run --rm -it \
  --env-file .env \
  lordraw/watchyourlan-mcp \
  python3.12 agent.py

⁠Environment variables

Create a .env file (never pass secrets as image layers):

# WatchYourLAN instance  (required)
WYL_BASE_URL=http://192.168.1.10:8840
WYL_TIMEOUT=10

# Transport (optional, default: stdio)
MCP_TRANSPORT=stdio   # or: sse
MCP_HOST=0.0.0.0      # SSE bind host
MCP_PORT=8080         # SSE bind port

# OpenRouter — only needed when running agent.py
OPENROUTER_API_KEY=sk-or-...
OPENROUTER_MODEL=google/gemini-2.0-flash-001

Variable	Required	Default	Description
`WYL_BASE_URL`	yes	`http://localhost:8840`	WatchYourLAN base URL
`WYL_TIMEOUT`	no	`10`	HTTP timeout (seconds)
`MCP_TRANSPORT`	no	`stdio`	Transport: `stdio` or `sse`
`MCP_HOST`	no	`0.0.0.0`	SSE server bind host
`MCP_PORT`	no	`8080`	SSE server port
`OPENROUTER_API_KEY`	agent only	—	API key from openrouter.ai
`OPENROUTER_MODEL`	no	`google/gemini-2.0-flash-001`	OpenRouter model ID

⁠Connect to Claude Desktop

⁠stdio transport

{
  "mcpServers": {
    "watchyourlan": {
      "command": "docker",
      "args": [
        "run", "--rm", "-i",
        "--env-file", "/absolute/path/to/.env",
        "lordraw/watchyourlan-mcp"
      ]
    }
  }
}

⁠SSE transport (server must be running)

{
  "mcpServers": {
    "watchyourlan": {
      "type": "sse",
      "url": "http://localhost:8080/sse"
    }
  }
}

⁠Network access

If WatchYourLAN runs on the same Docker host:

# Linux — share the host network stack
docker run --rm -i --network host \
  --env-file .env \
  lordraw/watchyourlan-mcp

# macOS / Windows — use the host gateway alias
# set WYL_BASE_URL=http://host.docker.internal:8840 in .env
docker run --rm -i \
  --env-file .env \
  lordraw/watchyourlan-mcp
