MCP 服务器（Drupal 适配器）

MCP Server for Drupal

This is a typescript based companion Model Context Protocol(MCP) server for the Drupal MCP module that works with the STDIO transport. In order to use SSE transport this server is not required.

[!IMPORTANT] 📖 Detailed docs are avilable at drupalmcp.io

Installation

The STDIO Binary is available through multiple distribution channels to accommodate various environments:

• Docker container
• Compiled binary
• JSR package

Here is a quick example of how to use the server with docker:

{
  "mcpServers": {
    "mcp-server-drupal": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/omedia/mcp-server-drupal",
        "--drupal-url=__DRUPAL_BASE_URL_"
      ],
      "env": {}
    }
  }
}

📖 For more details check the Installation section in the docs

Authentication

The server supports both authentication via environment variables. You can use either a auth token or a basic auth with username and password combination . The following environment variables are supported:

• DRUPAL_AUTH_TOKEN: The authentication token.
• DRUPAL_AUTH_USER: The username for authentication.
• DRUPAL_AUTH_PASSWORD: The password for authentication.

[!NOTE] Make sure to turn the authentication on the Drupal MCP module settings page.

[!NOTE] If both DRUPAL_AUTH_TOKEN and DRUPAL_AUTH_USER/DRUPAL_AUTH_PASSWORD are set, the token will be used over the username and password.

📖 Check the Authentication section in the docs for more details

MCP

• All instruments are defined by the Drupal API during the initialization phase

[!NOTE] The server now exposes the following

• Resources (templates, reads)
• Tools (calls)

No prompts are exposed by the server for now

Development

This project is built with Deno.

[!NOTE] Use deno version 2.0.0 or above

Install dependencies:

deno install

For development with auto-rebuild:

bun task dev

Build the server:

deno task build --output build/mcp-server-drupal

[!TIP] To build for the specific platform use the --target flag and check the docs

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a deno task:

deno task inspector --drupal-url [DRUPAL_BASE_URL]

Verifying the binaries and images

drupal_mcp_server binaries and container images are signed by cosign using identity-based signing.

You can verify your binary by downloading the signatures.tar.gz file from the release page, extracting the signature and running the following command:

cosign verify-blob ${YOUR_BINARY_NAME} \
--bundle signatures/${YOUR_BINARY_NAME}.bundle \
--certificate-oidc-issuer https://token.actions.githubusercontent.com \
--certificate-identity-regexp https://github.com/Omedia/mcp-server-drupal/.github/workflows/release.yml@refs/tags/v \
--certificate-github-workflow-repository Omedia/mcp-server-drupal

On the container side you can verify the image by running the following command:

cosign verify ghcr.io/omedia/mcp-server-drupal:latest \
  --certificate-oidc-issuer "https://token.actions.githubusercontent.com" \
  --certificate-identity-regexp "https://github.com/Omedia/mcp-server-drupal/.github/workflows/release.yml@refs/tags/v"
