Send and track email, read inbound mail, and manage contacts, segments, broadcasts, templates, domains and webhooks, through Resend’s hosted MCP server.
When you connect Resend:
- Flexkit connects with OAuth through Resend’s authorization server (
https://api.resend.com) and calls onlyhttps://mcp.resend.com/mcp. The agent never sees the credential. - On Resend’s approval screen, choose Full access to let the agent manage everything below, or Sending access to let it only send email from your verified domains. Sending email, sending or scheduling broadcasts, and creating, changing or removing anything in Resend follow your project’s approval rules.
- Revoke access any time with Disconnect, or by revoking the Flexkit grant from your Resend team’s authorized apps.
The resend-email skill teaches the agent to send only from a verified domain, confirm recipients and content before anything goes out, use broadcasts for bulk mail, and check delivery after sending.
