Mailgun MCP Server Integration

What does “Mailgun” MCP Server do?

The Mailgun MCP Server is an implementation of the Model Context Protocol (MCP) server for the Mailgun email APIs. It acts as a bridge between AI assistants (such as Claude Desktop) and the Mailgun service, allowing AI clients to programmatically send emails, retrieve email statistics, and manage email workflows. By connecting external AI systems with Mailgun’s API, the server enhances development and automation workflows—enabling tasks like sending transactional emails, fetching analytics, and integrating Mailgun capabilities directly into AI-powered applications. This integration allows developers and AI agents to interact with email infrastructure in a standardized, secure, and extensible way, streamlining communications and operational automation.

   • Obtain a Mailgun account and API key.

2. Clone the repository:

   git clone https://github.com/mailgun/mailgun-mcp-server.git
   cd mailgun-mcp-server
   

3. Install dependencies:

   npm install
   

4. Configure Claude Desktop:
   Create or modify the config file:

   • MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%/Claude/claude_desktop_config.json

   Add the following configuration:

   {
     "mcpServers": {
       "mailgun": {
         "command": "node",
         "args": ["CHANGE/THIS/PATH/TO/mailgun-mcp-server/src/mailgun-mcp.js"],
         "env": {
           "MAILGUN_API_KEY": "YOUR-mailgun-api-key"
         }
       }
     }
   }
   

5. Save and (re)start Claude Desktop.

6. Verify the setup by sending a test email or fetching statistics.

Securing API keys

API keys are set using environment variables in the configuration:

{
  "mcpServers": {
    "mailgun": {
      "command": "node",
      "args": ["CHANGE/THIS/PATH/TO/mailgun-mcp-server/src/mailgun-mcp.js"],
      "env": {
        "MAILGUN_API_KEY": "YOUR-mailgun-api-key"
      }
    }
  }
}

How to use this MCP inside flows

Using MCP in FlowHunt

To integrate MCP servers into your FlowHunt workflow, start by adding the MCP component to your flow and connecting it to your AI agent:

Click on the MCP component to open the configuration panel. In the system MCP configuration section, insert your MCP server details using this JSON format:

{
  "mailgun": {
    "transport": "streamable_http",
    "url": "https://yourmcpserver.example/pathtothemcp/url"
  }
}

Once configured, the AI agent is now able to use this MCP as a tool with access to all its functions and capabilities. Remember to change "mailgun" to whatever the actual name of your MCP server is and replace the URL with your own MCP server URL.

Overview

Our opinion

The Mailgun MCP server is functional and minimally documented, with clear setup instructions for Claude Desktop and support for secure API key management. However, it lacks details on prompt templates, resources, and tools, reducing discoverability for more advanced MCP features. The repository is open source with a standard license and moderate community interest.

Overall, we’d rate this MCP at 4/10: it covers the basics but misses many advanced or best-practice MCP features.
