OpenCode - SendKit

OpenCode is an open-source AI coding assistant that runs in your terminal. You can connect it to SendKit’s MCP server to manage your email infrastructure with natural language.

Prerequisites

OpenCode installed
A SendKit API key with Full permission

Setup

Open the configuration file

Edit your OpenCode configuration at .opencode.json in your project root (or ~/.opencode.json for global config):

{
  "mcpServers": {
    "sendkit": {
      "type": "sse",
      "url": "https://mcp.sendkit.dev/sendkit",
      "headers": {
        "Authorization": "Bearer sk_your_api_key_here"
      }
    }
  }
}

Replace sk_your_api_key_here with your actual API key from the SendKit dashboard.

Restart OpenCode

Close and reopen OpenCode to load the new MCP configuration.

Verify the connection

Ask OpenCode to interact with your SendKit account:
