Mailjet MCP Server

The Mailjet MCP Server bridges the gap between AI assistants and the Mailjet email‑marketing platform, allowing agents such as Claude Desktop to perform complex mailing operations without writing custom API calls. By exposing Mailjet’s contact, campaign, segmentation, statistics, and workflow endpoints as standardized MCP tools, developers can ask an AI to manage email lists, launch campaigns, or analyze delivery metrics—all through natural language interactions.

At its core, the server authenticates with Mailjet using a single environment variable that bundles the API key and secret. It then translates AI‑generated tool calls into authenticated HTTP requests, handling pagination, error mapping, and response formatting behind the scenes. This abstraction lets developers focus on higher‑level business logic rather than boilerplate authentication and endpoint management.

Key capabilities include:

• Contact Management – add, update, or query subscribers across multiple lists.
• Campaign Operations – create, schedule, and monitor email campaigns with real‑time status reports.
• Segmentation – build dynamic audience segments based on user attributes or engagement history.
• Analytics & Reporting – fetch delivery, open, click, and bounce statistics, and generate visual charts for quick insights.
• Workflow Automation – trigger Mailjet workflows or integrate with other services through chained tool calls.

Real‑world scenarios benefit from this server in several ways. Marketing teams can ask an AI to “find the list with the highest open rate” or “launch a weekend promotion campaign,” while customer success teams might request “create a segment of users who opened last month’s newsletter.” The server also supports iterative refinement: an AI can retrieve statistics, analyze trends, and automatically adjust segmentation rules—all within a single conversational session.

Integration with AI workflows is seamless: the MCP server communicates over standard I/O, so any compliant client can register it as a tool provider. Developers can then embed the Mailjet server into larger AI‑driven pipelines—combining data extraction, natural language understanding, and automated email outreach without custom glue code. The result is a powerful, extensible workflow that leverages Mailjet’s full feature set while keeping the developer experience intuitive and consistent across tools.
