CMS MCP Hub

CMS MCP Hub

A universal connector hub that proxies Claude.ai tool calls to any CMS that runs an MCP server (Drupal, Joomla, WordPress, etc.).

How it works

Claude.ai  ──MCP──▶  cms-mcp-hub  ──SSE──▶  Drupal MCP server
                                  ──SSE──▶  Joomla MCP server
                                  ──SSE──▶  WordPress MCP server

Each "connector" has a name and a URL pointing to that CMS's hosted MCP server.The hub fetches all tools from each server, registers them prefixed by connector name,and proxies Claude's calls to the right backend.

Tool naming: <connector-name>__<original-tool-name>Example: drupal-site-a__get_node

Requirements

• Node.js 18+
• A Drupal site with the mcp_server module installed (or any CMS MCP server)

Setup

# 1. Install dependencies
npm install

# 2. Start the hub
npm start

# 3. (Optional) Custom port
PORT=4000 npm start

Hub starts on http://localhost:3456 by default.

Endpoints

Adding connectors

Web UI

Open http://localhost:3456/ui in your browser.

CLI

# Link the CLI globally (once)
npm link

# Add a connector
cms-hub add --name drupal-site-a \
            --url https://yoursite.com/mcp/sse \
            --token YOUR_API_TOKEN \
            --description "Production Drupal site"

# List all connectors
cms-hub list

# Check hub status
cms-hub status

# Refresh tools (after adding modules to the CMS)
cms-hub refresh --name drupal-site-a

# Remove a connector
cms-hub remove --name drupal-site-a

Config file (connectors.json)

Edit directly then restart the hub:

{
  "connectors": [
    {
      "name": "drupal-site-a",
      "url": "https://yoursite.com/mcp/sse",
      "token": "YOUR_API_TOKEN",
      "description": "Production Drupal site"
    }
  ]
}

Connect Claude.ai

1. In Claude.ai → Settings → Integrations → Add MCP Server
2. Enter: http://localhost:3456/mcp (or your hosted hub URL)
3. Claude will discover all tools from all connected CMS connectors
