From the repository
Install via Smithery or manually. For manual setup, clone the repository and add a configuration entry to your MCP client’s JSON file (e.g., claude_desktop_config.json) with the required environment variables: SENDGRID_API_KEY, CRONJOB_API_KEY, FROM_EMAIL, and optional TZ. Then ask your LLM to create, get, or delete scheduled emails. If no recipient email is specified, the server defaults to sending to the sender’s email address.
