Concrete CMS MCP Server

A Model Context Protocol (MCP) server for Concrete CMS built with TypeScript.

Installation

git clone https://github.com/MacareuxDigital/concretecms-mcp-server.git
cd concretecms-mcp-server
npm install && npm run build

Usage

Enable API in Concrete CMS

Since the MCP server uses the Concrete CMS API, you need to enable it in your Concrete CMS installation first. Please refer to the Concrete CMS documentation for more information.

Connect your LLM to the local Concrete CMS MCP Server

Here's an example configuration for Claude Desktop:

{
  "mcpServers": {
    "concretecms": {
      "command": "node",
      "args": [
        "/path/to/concretecms-mcp-server/dist/index.js"
      ],
      "env": {
        "CONCRETE_CANONICAL_URL": "https://your-concrete.example",
        "CONCRETE_API_CLIENT_ID": "YOUR_API_CLIENT_ID",
        "CONCRETE_API_CLIENT_SECRET": "YOUR_API_CLIENT_SECRET",
        "CONCRETE_API_SCOPE": "account:read system:info:read"
      }
    }
  }
}

• Set CONCRETE_CANONICAL_URL to the URL of your Concrete CMS installation.
• Set CONCRETE_API_CLIENT_ID and CONCRETE_API_CLIENT_SECRET to the credentials of a registered API integration.
• Set CONCRETE_API_SCOPE to the scopes you want to request. You can find a list of available scopes from https://your-concrete.example/index.php/dashboard/system/api/scopes.

After you've configured the MCP server, please restart Claude Desktop. It'll automatically opens an authorization window, then sign in and authorize the requested scopes. Now you should be able to get information about your Concrete CMS in a chat. A refresh token will be saved in .tokens.json in the concretecms-mcp-server directory, so you don't need to sign in again.

For more information about local MCP servers, please refer to the Claude Desktop documentation.

Use your own OpenAPI specification

The MCP server is loading openapi.yml to know which endpoints are available in the Concrete CMS API. The bundled openapi.yml file is generated from the Concrete CMS default installation, but you can also use your own OpenAPI specification. If you added some Express Objects to your Concrete CMS installation and want to use them in your chat, you can generate a new OpenAPI specification from your installation and use it instead.

1. Check "Include this entity in REST API integrations." in the Express Object settings.
2. Open https://your-concrete.example/index.php/ccm/system/api/openapi.json in your browser, and copy the JSON output.
3. Replace the openapi.yml file in the concretecms-mcp-server directory with your own OpenAPI specification.
