Umbraco MCP Server

Umbraco MCP Server

!Happydance Labs

A Model Context Protocol (MCP) server implementation for Umbraco CMS, allowing LLMs to access and manipulate Umbraco content through standardized interfaces.

Overview

This repository provides a Model Context Protocol server that connects to Umbraco CMS, enabling AI models like Claude to:

• Retrieve content from Umbraco
• Execute operations against the Umbraco Management API
• Access document types, media, and other Umbraco resources
• Perform actions through standardized tool interfaces

Installation

# Clone the repository
git clone https://github.com/HappydanceLabs/umbraco-mcp-server.git

# Navigate to the project directory
cd umbraco-mcp-server

# Install dependencies
npm install

# Generate Umbraco API types
npm run generate:umbraco

# Start the development server
npm run dev

The server will be available at http://localhost:8787/

Connect the MCP Inspector

To explore the MCP API and test available resources and tools:

1. Start the MCP Inspector:

   npm run mcp:inspector

1. In the Inspector interface, switch the Transport Type to SSE and enter http://localhost:8787/mcp as the URL.

1. Click "Connect" and follow any authentication prompts.

1. Once connected, you can list and call the available resources and tools.

Connect to Claude Desktop

To use this MCP server with Claude:

1. Install Claude Desktop and follow Anthropic's MCP Quickstart

1. In Claude Desktop, go to Settings > Developer > Edit Config

1. Replace the configuration with:

{
  "mcpServers": {
    "umbraco": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "http://localhost:8787/mcp"
      ]
    }
  }
}

1. Restart Claude and you'll be able to use the Umbraco tools directly from Claude.

Deployment

1. Create a KV namespace for OAuth:

   npx wrangler kv namespace create OAUTH_KV

1. Add the KV namespace ID to wrangler.jsonc

1. Deploy to Cloudflare Workers:

   npm run deploy

1. Update your Claude configuration to use your deployed URL:

   {
     "mcpServers": {
       "umbraco": {
         "command": "npx",
         "args": [
           "mcp-remote",
           "https://your-worker-url.workers.dev/sse"
         ]
       }
     }
   }

Project Structure

• /src/api: Umbraco API clients and interfaces
• /src/resources: MCP resource implementations for reading Umbraco data
• /src/tools: MCP tool implementations for executing operations
• /src/helpers: Utility functions and shared code
• /src/types: TypeScript type definitions

Development

This project uses the Model Context Protocol TypeScript SDK and Cloudflare Agents SDK to implement resources and tools according to the MCP specification. Hosted and deployed on a Cloudflare Worker.

For more information on the MCP protocol, see the official documentation.

Debugging

If you encounter issues:

# Test direct connection to the MCP server
npx mcp-remote http://localhost:8787/sse

# Clear MCP authentication cache if needed
rm -rf ~/.mcp-auth
