This project provides a Model Context Protocol (MCP) server for the Mailjet API, enabling compatible AI agents (e.g. Claude Desktop) to interact with Mailjet's contact, campaign, segmentation, statistics, workflow (and more) APIs through a standardized tool interface.

1. Clone the repository:

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

2. Install dependencies and build:

   pnpm install

3. 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

Then start the MCP server:

node src/mailjet-mcp.js

Add the following configuration:

{
    "mcpServers": {
        "mailjet": {
            "command": "node",
            "args": ["CHANGE/THIS/PATH/TO/mailjet-mcp-server/src/mailjet-mcp.js"],
            "env": {
                "MAILJET_API_KEY": "YOUR_api_key:YOUR_secret_key"
            }
        }
    }
}

The following environment variables are currently supported by the server:

MAILJET_API_KEY="your_api_key:your_secret_key" # REQUIRED, used for authenticating your account
MAILJET_API_REGION="eu" # OPTIONAL, used to change to the EU servers, if desired

Run the local test suite with:

NODE_ENV=test pnpm test

Which of my contacts lists has the most subscribers?

Would you be able to make a chart with email delivery statistics for the past week?

The MCP server communicates over stdio, please refer to Debugging section of the Model Context Protocol.
