Resend Skill

The Resend skill enables AI agents to send emails through the Resend API using our official recommendations. It provides a streamlined interface for sending single and batch emails with built-in error handling and retry logic.

This skill is part of the resend-skills repository, which also includes the Agent Email Inbox skill for secure inbound email processing. When you run the install command, you'll be prompted to choose which skills to install.

Clients that support the Agent Plugins spec can install the same repository as a plugin. That install adds these skills and the remote MCP server together. The MCP server docs list the install command for each supported client.
