Hangsolow.OptiMcpServer 1.0.6

Hangsolow.OptiMcpServer

⚠️ Development tool only — do not use in production

This package is intended exclusively for local development against a local database. It exposes unauthenticated content read/write operations over HTTP. Running it in a production or shared environment is a serious security risk and is strongly discouraged.

An MCP (Model Context Protocol) server library for Optimizely CMS 12. Install it into your local Optimizely development project to expose content operations as tools callable by AI assistants (Claude, Copilot, etc.).

What it does

Exposes the following MCP tools over HTTP (/mcp):

Two guided prompts help AI assistants scaffold the correct tool calls:

• create_page — lists available page types and generates a creation workflow
• create_block — lists available block types and generates a creation workflow

Requirements

• Optimizely CMS 12
• .NET 8 or .NET 10
• SQL Server — local development database only

Installation

Install this package only in your development project configuration (e.g. guarded by #if DEBUG or an environment check). Never deploy it to staging or production.

dotnet add package Hangsolow.OptiMcpServer

Integration

Startup.cs (traditional Optimizely bootstrap)

using OptiMcpServer;

public class Startup
{
    private readonly IConfiguration _configuration;

    public Startup(IConfiguration configuration)
    {
        _configuration = configuration;
    }

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddCms()
                .AddOptiMcpServer(_configuration);
    }

    public void Configure(IApplicationBuilder app)
    {
        app.UseRouting();
        app.UseEndpoints(endpoints =>
        {
            endpoints.MapDefaultControllerRoute();
            endpoints.MapMcp("/mcp"); // exposes /mcp
        });
    }
}

AddOptiMcpServer returns an IMcpServerBuilder, so you can chain additional tool assemblies:

services.AddCms()
        .AddOptiMcpServer(_configuration)
        .WithToolsFromAssembly(typeof(MyCustomTool).Assembly);

appsettings.json

{
  "ConnectionStrings": {
    "EPiServerDB": "Server=.;Database=MyDb;Integrated Security=True;TrustServerCertificate=True"
  },
  "OptiMcpServer": {
    "PageBaseClass": "EPiServer.Core.PageData",
    "BlockBaseClass": "EPiServer.Core.BlockData"
  }
}

Set PageBaseClass and BlockBaseClass to your site's abstract base types (e.g. MySite.Models.Pages.SitePageData) so the create_page and create_block prompts only surface content types relevant to your project.

MCP endpoint

Once running, the MCP server is available at:

http://<host>/mcp

Configure your AI client to connect to this URL using the Streamable HTTP transport.
