Cursor

1. First, you need to authorize Resend to send emails from your domain or email. Follow the steps here to set that up and get a Resend API key.
2. Clone this project locally. Edit index.ts and replace me@yoko.dev to your own email to send emails from
3. Run npm install, npm run build under the project dir. You should now see a /build/index.js generated - this is the MCP server script!

Then go to Cursor Settings -> MCP -> Add new MCP server

• Name = [choose your own name]
• Type = command
• Command: node ABSOLUTE_PATH_TO_MCP_SERVER/build/index.js --key=YOUR_RESEND_API_KEY --sender=OPTIONAL_SENDER_EMAIL_ADDRESS --reply-to=OPTIONAL_REPLY_TO_EMAIL_ADDRESS_ONE --reply-to=OPTIONAL_REPLY_TO_EMAIL_ADDRESS_TWO

You can get Resend API key here: https://resend.com/

Now you can test out sending emails by going to email.md, replace the to: email address, select all in email md, and hit cmd+l. You can now tell cursor to "send this as an email" in the chat. Make sure Cursor chat is in Agent mode by selecting "Agent" on lower left side dropdown
