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)

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

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
