If you’re developing with AI, Resend offers several resources to improve your experience.

​
Prerequisite: Create an API Key

Currently, we require a human to create a Resend account. Once you have an account, you’ll need to create an API key. With an API key, your agent can perform many other tasks.
To send or receive with Resend, you’ll need to verify a domain. While an agent can create a domain, the API returns DNS records you will need to add in your DNS provider before verifying your DNS records. You may find it easier to verify your domain in the dashboard.

Resend MCP Server

MCP is an open protocol that standardizes how applications provide context to LLMs. Among other benefits, it provides LLMs tools to act on your behalf. Our MCP server is open-source and covers our full API surface area. To get started, clone and build the repo: 
git clone https://github.com/resend/resend-mcp.git
With the MCP server built, you can add it to a supported MCP client like Claude Code, Cursor, or Codex.

Resend Docs for Agents

You can give your agent current docs in a context-aware way in three ways:
  1. Markdown docs Every doc includes a markdown version (append md to any page) 
    Docs for this page: https://resend.com/docs/ai-onboarding.md
  2. Full llms.txt Give your agent all our docs in a single file. 
    Here are the Resend docs: https://resend.com/docs/llms-full.txt
  3. MCP Docs server For a more structured approach using MCP tools, you can install our MCP docs server in any MCP client, like Cursor, Codex, or Claude Code.

OpenClaw Guide

OpenClaw is a tool that allows you to build and deploy AI agents. Agents can interact with APIs like Resend. Equipping your agent with its own email inbox can be a powerful tool to unlock new workflows. Alternatively, give it access to your Resend account to support agentic flows for sending and receiving emails.
