Follow the instructions below to integrate Resend MCP server to your AI application using our API or SDK.

​
Prerequisites

​
1. Create a Resend MCP Server

Use the following endpoint to create a new remote Resend MCP server instance:

​
Request

from klavis import Klavis
from klavis.types import McpServerName

klavis_client = Klavis(api_key="<YOUR_API_KEY>")

# Create a Resend MCP server instance
resend_server = klavis_client.mcp_server.create_server_instance(
    server_name=McpServerName.RESEND,
    user_id="<YOUR_USER_ID>"
)

​
Response

{
  "serverUrl": "https://resend-mcp-server.klavis.ai/sse?instance_id=<instance-id>",
  "instanceId": "<instance-id>"
}
serverUrl specifies the endpoint of the Resend MCP server, which allows you to send emails through the Resend service.
instanceId is used for authentication and identification of your server instance.

​
2. Configure Resend API Key

To use the Resend MCP Server, you need to configure it with your Resend API key.

​
Setting up Resend API Key

curl --request POST \
  --url https://api.klavis.ai/mcp-server/instance/set-auth \
  --header 'Authorization: Bearer <YOUR_KLAVIS_API_KEY>' \
  --header 'Content-Type: application/json' \
  --data '{
  "instanceId": "<YOUR_INSTANCE_ID>",
  "authData": {
    "token": "<YOUR_RESEND_API_KEY>"
  }
}'

​
