Or add to your MCP client config:

{
  "mcpServers": {
    "resend": {
      "command": "npx",
      "args": ["-y", "@aiwerk/mcp-server-resend"],
      "env": {
        "RESEND_API_KEY": "re_..."
      }
    }
  }
}

Environment variables

Name	Required	Description
`RESEND_API_KEY`	✅	Resend API key (starts with `re_`). Get one at resend.com/api-keys.
`RESEND_API_BASE_URL`	—	Override API base URL (default: `https://api.resend.com`).
`RESEND_API_TIMEOUT_MS`	—	Request timeout in milliseconds (default: `30000`).

Auth

Sign up at resend.com (free tier: 3,000 emails/month, 100/day).
Open API Keys in the dashboard and create a key with Full access.
Copy the key (starts with re_) into RESEND_API_KEY.
To send from your own address, verify a domain under Domains. For testing, use [email protected] (sender) → [email protected] / [email protected] / [email protected] without domain setup.
