CronGrid — an MCP server scheduling SendGrid Cron Jobs!

Description

This MCP server enables LLMs to POST, GET, and DELETE cron jobs that schedule email sends via SendGrid.

Prerequisites

Claude Desktop (or another MCP server-compatible LLM interface of your choice) installed on your local machine
If using Smithery: Node.js (version 14 or higher) installed
If running locally: uv installed
SendGrid account with verified single sender email address
Cron-Job.Org account

Installation

Installing via Smithery

To install CronGrid automatically via Smithery (example for Claude Desktop):

npx -y @smithery/cli install @chaser164/sendgrid-cronjob-mcp --client claude

Installing Manually

Open your terminal or command line.
Run git clone https://github.com/chaser164/sendgrid-cronjob-mcp.git
Add the below to your MCP server-compatible interface of choice (e.g., ~/Library/Application Support/Claude/claude_desktop_config.json)

{
  "mcpServers": {
    "cronjob_email_mcp": {
      "command": "/path/to/uv",
      "args": [
        "--directory",
        "/path/to/sendgrid-cronjob-mcp",
        "run",
        "email-schedule-send-mcp-server.py"
      ],
      "env": {
        "SENDGRID_API_KEY": "<SendGrid API key>",
        "CRONJOB_API_KEY": "<Cron-Job.Org API key>",
        "FROM_EMAIL": "<SendGrid verified single sender email>"
        "TZ": "<timezone value>",
      }
      
    }
  }
}

Usage

Ask your LLM to create, get, and delete scheduled emails
This MCP also has the ability to get the current date/time to enhance its scheduling capabilities
If a "to email" is not specified, the mcp will send an email to yourself (e.g., "remind me to dance" will send an email to the specified SendGrid sender identity's email address)
