MCP Server

The plugin registers Resend's hosted MCP server at https://mcp.resend.com/mcp (streamable HTTP), giving agents tool access to the full Resend API. It authenticates via OAuth — your client walks you through sign-in on first connect, so no API key or header configuration is needed.
