Resend Email MCP Server + Cursor FAQ

Where is the Cursor config file?

Cursor reads MCP servers from ~/.cursor/mcp.json. Paste the Resend Email MCP Server config there under the "mcpServers" key and restart the client.

Is Resend Email MCP Server safe to use with Cursor?

Where do I get the API key?

Generate one at resend.com/api-keys and provide it as the RESEND_API_KEY environment variable. The server reads it for all API calls.

Can I send to any email address?

To send to external recipients you must verify a sending domain at resend.com/domains. Without a verified domain you can only use Resend's onboarding/test addresses.

Do I have to set a sender address?

No. You can set SENDER_EMAIL_ADDRESS as a default, but if you don't, the server will prompt for a sender when you invoke a send tool.
