Umbraco MCP

An MCP (Model Context Protocol) server for Umbraco CMS that unlocks AI-powered content management. It provides comprehensive access to the Umbraco Management API, enabling your AI agent to perform back office tasks through natural conversation - freeing you from the UI and making complex, repetitive workflows that would be tedious or impossible manually become effortless.

Intro

The MCP server authenticates using an Umbraco API user, ensuring secure, permission-based access to the Umbraco Management API. This means you maintain complete control over what your AI agent can do through Umbraco's standard user permission system - no special security model required.

Quick Start

1. Create an Umbraco API User

First, create an Umbraco API user with appropriate permissions. You can find instructions in Umbraco's documentation.

2. Install in Claude Desktop

Download and install the Claude Desktop app, then add the MCP server to your configuration:

1. Open Claude Desktop Settings > Developer > Edit Config
2. Add this configuration to your claude_desktop_config.json:

{
  "mcpServers": {
    "umbraco-mcp": {
      "command": "npx",
      "args": ["@umbraco-cms/mcp-dev@17"],
      "env": {
        "NODE_TLS_REJECT_UNAUTHORIZED": "0",
        "UMBRACO_CLIENT_ID": "your-api-user-id",
        "UMBRACO_CLIENT_SECRET": "your-api-secret",
        "UMBRACO_BASE_URL": "https://localhost:{port}",
        "UMBRACO_INCLUDE_TOOL_COLLECTIONS": "document,media,document-type,data-type"
      }
    }
  }
}

3. Fully restart Claude Desktop (including in the system tray on Windows)

Hosted Deployment

The Cloudflare Worker entry point (src/worker.ts) supports two deployment modes, selected at request time by the @umbraco-cms/mcp-hosted library:

• Single-tenant (default) — the worker authenticates against the UMBRACO_BASE_URL configured in wrangler.toml. This is the existing behavior and requires no extra configuration.
• Multi-tenant Umbraco Cloud — set UMBRACO_CLOUD_ROUTING_ENABLED = "true" under [vars] in wrangler.toml. Requests to /at/{alias}/... resolve the upstream Umbraco Cloud project for {alias} and issue access tokens scoped to that resource per the MCP resource-indicator spec. Each Umbraco Cloud project served by the worker must register an OpenIddict client with id umbraco-cms-developer-mcp-hosted.

siteRouting is wired unconditionally; the per-request toggle is the env var.
