{
  "mcpServers": {
    "codesys-mcp": {
      "command": "uvx",
      "args": [

    }
  }
}

Or install with pip: pip install codesys-mcp

README Excerpt

MCP server for CODESYS with a persistent UI instance and file-based IPC. Unlike headless-only approaches that spawn a new CODESYS process per command, this server launches CODESYS **with its UI visible** and keeps it running. MCP tool calls are sent to the same instance via a file-based IPC watcher, so changes appear in real-time and the user can interact with the IDE alongside AI-driven automation.
