Configuration

Usage with Cline、Cursor、Claude and other applications

Add this to MCP settings of your application:

Using uvx

{
    "mcpServers":
    {
        "nacos-mcp-router":
        {
            "command": "uvx",
            "args":
            [
                "nacos-mcp-router@latest"
            ],
            "env":
            {
                "NACOS_ADDR": "<NACOS-ADDR>, optional, default is 127.0.0.1:8848",
                "NACOS_USERNAME": "<NACOS-USERNAME>, optional, default is nacos",
                "NACOS_PASSWORD": "<NACOS-PASSWORD>, required"
            }

}

You may need to put the full path to the uvx executable in the command field. You can get this by running which uvx on MacOS/Linux or where uvx on Windows.
