Use MailAgent in your project

Full openness = your Cloudflare Worker, your Resend inbox domain, your API key. No dependency on our hosted API or approval from us.

Self-host (recommended)

1. Clone GitHub (MIT)
2. Neon + Resend + npm run db:migrate
3. npm run deploy → your *.workers.dev
4. Set your own API_KEY (wrangler secret)
5. Resend webhook → https://your-worker/webhooks/resend

Cursor agent (MCP)

Add to your repo root:

// .cursor/mcp.json
{
  "mcpServers": {
    "mailagent": {
      "command": "node",
      "args": ["/path/to/MailAgent/mcp/dist/index.js"],
      "env": {
        "MAILAGENT_API_URL": "https://your-worker.workers.dev",
        "MAILAGENT_API_KEY": "your-secret"
      }
    }
  }
}

Run npm run build:mcp in MailAgent. Copy skill from .cursor/skills/mailagent-mcp/ optional.
