SendGrid MCP Server

A Model Context Protocol (MCP) server that provides access to SendGrid’s Marketing API for email marketing and contact management. https://docs.sendgrid.com/api-reference/how-to-use-the-sendgrid-v3-api

Demo

In this demo, we ask the Cline SendGrid agent to make a new contact list, add my emails to it, automatically generate a template for Lost Cities facts, and send the email to the list. In this process, Cline will automatically realize that it needs to know the verified senders we have, and which unsubscribe group to use. A pretty email is delivered to my inboxes, delighting me with Lost Cities!

Important Note on API Support

This server exclusively supports SendGrid’s v3 APIs and does not provide support for legacy functionality. This includes:

• Dynamic templates only - legacy templates are not supported
• Marketing API v3 for all contact & contact list operations
• Single Sends API for bulk email sending
