description Overview

mcp-sendgrid — SendGrid MCP Server

Send transactional and marketing emails at scale — let AI agents trigger emails, manage templates, maintain contact lists, and monitor deliverability via SendGrid.

SendGrid powers email delivery for over 80,000 companies, sending billions of emails every month. This MCP server gives your agents the full SendGrid v3 API: sending single and bulk emails with dynamic templates, managing marketing contacts and lists, pulling delivery and engagement stats, monitoring bounces, and managing verified sender identities.

Live endpoint: https://mcp.aerostack.dev/s/aerostack/mcp-sendgrid

What You Can Do

  • Send transactional emails from any trigger — signups, payments, errors, or alerts — with dynamic template data
  • Send personalized bulk emails to thousands of recipients with per-recipient template variables
  • Monitor email deliverability with global stats, bounce lists, and per-template analytics
  • Maintain marketing contact lists and sync subscribers from your application automatically

Frequently asked questions

What is the SendGrid MCP server and what can it do? +

The SendGrid MCP server is hosted on Aerostack and exposes these tools to your AI agent: `_ping`, `send_email`, `send_bulk_email`, `send_template_email`, `schedule_email`. You get one hosted URL — no self-hosting — that works from Claude, Cursor, ChatGPT, Gemini, VS Code, or any MCP-compatible client, and you can share it with your team or combine it with other MCP servers in a workspace.

Is the SendGrid MCP server hosted, or do I have to run it myself? +

It's hosted on Aerostack's edge infrastructure — you don't deploy or maintain anything. Add it to a workspace and you get one authenticated URL, with secrets encrypted, that any AI agent or editor can connect to. Use it solo or share the same URL across your whole team.

Which AI agents and editors can use the SendGrid MCP server? +

Any MCP client: Claude and Claude Code, Cursor, ChatGPT, Gemini, Windsurf, Cline, VS Code, and custom agents. Because it's one hosted URL, the same SendGrid MCP server works everywhere — and you can compose it with other MCP servers, skills, and functions behind a single workspace URL.

How do I install the SendGrid MCP server in Claude Desktop? +

Add the following to your Claude Desktop config (`claude_desktop_config.json`): ```json { "mcpServers": { "@aerostack/mcp-sendgrid": { "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-sendgrid"] } } } ``` Then restart Claude Desktop and the tools will appear automatically.

How do I use the SendGrid MCP server in Cursor? +

In Cursor, open **Settings → MCP** and add: ```json { "name": "@aerostack/mcp-sendgrid", "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-sendgrid"] } ``` Save and reload Cursor. The MCP tools will be available in Agent mode.

Does SendGrid MCP require authentication? +

Yes. SendGrid requires authentication. Check the MCP's documentation for the required credentials.
