ioBroker Simple-API MCP Server

This project provides a Model Context Protocol (MCP) server that connects to your ioBroker instance via the simple-api adapter. It enables MCP-compatible clients (such as Claude Desktop, Cursor, VSCode, etc.) to interact with your ioBroker installation using standardized tools.

Features

• Exposes ioBroker simple-api endpoints as MCP tools
• Supports authentication via query parameters, Basic Auth, or Bearer tokens
• Easily configurable via CLI arguments or environment variables
• Designed for use with MCP clients (stdio transport)

Installation

You can run this server directly with npx (no installation required) or clone and run locally.

Usage with MCP Clients

Add the following to your MCP client configuration (e.g., Claude Desktop, Cursor, VSCode, etc.):

"servers": {
  "iobroker-simple-api-mcp-server": {
    "type": "stdio",
    "command": "npx",
    "args": [
      "iobroker-simple-api-mcp-server",
      "--host", "http://localhost:8087",
      "--authType", "query",
      "--user", "admin",
      "--pass", "secret"
    ]
  }
}

You can also provide authentication and host information via environment variables:

IOB_AUTH_TYPE=query IOB_USER=admin IOB_PASS=secret IOB_HOST=http://localhost:8087 

Authentication Options

• Query parameters:
  --authType=query --user=admin --pass=secret
• Basic Auth:
  --authType=basic --user=admin --pass=secret
• Bearer Token:
  --authType=bearer --token=YOUR_TOKEN

All options can be set via CLI arguments or environment variables (IOB_AUTH_TYPE, IOB_USER, IOB_PASS, IOB_TOKEN, IOB_HOST).

Supported Tools

• getPlainValue(stateID) – Get the plain value of a state
• getState(stateID) – Get the value and info of a state
• setState(stateID, value) – Set the value of a state
• toggleState(stateID) – Toggle a boolean state
• ...and more (see ioBroker.simple-api documentation)
