Adding New Tools

To add new tools, simply add new methods to the DnnTools class:

2. Add a new method in the appropriate region (or create a new region)
3. Decorate the method with the [McpServerTool] and [Description] attributes
4. Rebuild the project

For example:

[McpServerTool]
[Description("Get page details")]
public async Task<string> GetPage(int pageId, int portalId)
{
    var data = await ExecuteCommandAsync(portalId, $"get-page --id {pageId}");
    return JsonSerializer.Serialize(data, new JsonSerializerOptions { WriteIndented = true });
}
