Cursor

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.
Clone this project locally. Edit index.ts and replace [email protected] to your own email to send emails from
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

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

Claude desktop

Same set up as above, and then add the following MCP config

  "mcpServers": {
    "resend": {
      "command": "node",
      "args": ["ABSOLUTE_PATH_TO_MCP_SERVER/build/index.js"],
