Beehiiv

A Model Context Protocol (MCP) server for integrating with the Beehiiv newsletter platform. This MCP provides tools to interact with the Beehiiv API, allowing you to retrieve subscriber information and manage your newsletter operations programmatically.

🚀 Features

• Get Subscribers: Retrieve subscriber data with advanced filtering and pagination
• TypeScript Support: Full TypeScript implementation with proper error handling
• Environment Configuration: Secure API key and publication ID management
• Comprehensive Filtering: Support for status, tier, email, and custom field filtering
• Pagination Support: Cursor-based pagination for efficient data retrieval

🛠️ Quick Start

Prerequisites

• Node.js 18.0.0 or higher
• A Beehiiv account with API access
• Your Beehiiv API key and Publication ID

Installation

Install in Claude Desktop

1. Prepare your Beehiiv credentials

   • You will need your Beehiiv API key and your Publication ID.
   • In Beehiiv, go to Settings → Integrations to create or view your API key.

   

2. Upload the MCP bundle to Claude Desktop

   • Open the Claude Desktop app.
   • Navigate to Settings → Extensions.
   • Drag-and-drop the bundle file beehiiv-mcp.mcpb, or go to Advanced settings → Install extension and select the same file from the project root.

   

3. Configure environment variables for the extension

   • In the extension configuration screen, add the required variables:
     • BEEHIIV_API_KEY: your Beehiiv API key
     • BEEHIIV_PUBLICATION_ID: your Beehiiv publication ID
   • Save the configuration.

   

4. Use it in Claude Desktop app

   • Open a chat and ask something like: "Use the Beehiiv MCP to fetch subscribers".
   • You can also verify tools are available via the Extensions view.

Note: The MCP bundle file is included at the repository root as beehiiv-mcp.mcpb. If you build from source, you can continue to use the JSON-based configuration below as an alternative to the bundle.
