Claude Code is Anthropic’s CLI tool for working with Claude directly in your terminal. You can connect it to SendKit’s MCP server to manage your email infrastructure with natural language.

​
Prerequisites

  • Claude Code installed (npm install -g @anthropic-ai/claude-code)
  • A SendKit API key with Full permission

​
Setup

1

Add the MCP server

Run the following command in your terminal:
claude mcp add --transport http sendkit https://mcp.sendkit.dev/sendkit \
  --header "Authorization: Bearer sk_your_api_key_here"
Replace sk_your_api_key_here with your actual API key from the SendKit dashboard.
This adds the server to your project’s .mcp.json file. To add it globally instead, append the --scope user flag.
2

Verify the connection

Start Claude Code and ask it to interact with your SendKit account:
claude

List all my SendKit domains

​
Manual configuration

You can also configure the server manually by creating a .mcp.json file in your project root: 
{
  "mcpServers": {
    "sendkit": {
      "type": "http",
      "url": "https://mcp.sendkit.dev/sendkit",
      "headers": {
        "Authorization": "Bearer sk_your_api_key_here"
      }
    }
  }
}
For global configuration, add the same to ~/.claude.json.

​
Example prompts

Once connected, you can use natural language to manage your SendKit account: 
Create a sender called "Support" with username "support" on my verified domain

Show me all contacts that are subscribed to the "Newsletter" list

Send a test email from support@mydomain.com to test@example.com with subject "Hello"

What's my sending reputation right now?
