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>",
      }
      
    }
  }
}

NOTE: timezone environment variable values must be chosen from this list. The default timezone value is UTC.

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)
