Claude Code How to use Resend with Claude Code
You want Resend inside Claude Code so it can send transactional receipts, monitor delivery status, reschedule pending emails, and cancel scheduled emails — without you copy-pasting between tabs. Here is the whole setup, once.
Create your Resend gateway
The gateway is the thing Claude Code connects to, and it is where you decide which Resend tools an agent may use. You create it once and every client reuses it.
-
Create an Arcade account
Sign up and open the dashboard. The free tier is enough to follow this through.
-
Create an MCP Gateway and select your Resend tools
In the dashboard, create a gateway and pick the Resend tools you want to expose. The gateway is what your client connects to, and it is where tool access is decided.
-
Copy your gateway URL
Every client below needs it.
https://api.arcade.dev/mcp/<YOUR-GATEWAY-SLUG>
Connect the gateway to Claude Code
-
Add the gateway as a remote HTTP MCP server
claude mcp add arcade --transport http "<YOUR_ARCADE_GATEWAY_URL>"
-
Verify it was added
claude mcp get arcade claude mcp list
-
Try it out
Open Claude Code in your project and ask it to use one of your Resend tools.

Try these Resend prompts
Claude Code can now act on your Resend account. Click a prompt to copy it.
Restrict the agent to checking delivery status, or require approval before it sends, reschedules, or cancels a scheduled email. Pair it with Contextual Access policies so agents cannot take those actions without the access your policy allows.
