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

1

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.
2

Restart OpenCode

Close and reopen OpenCode to load the new MCP configuration.
3

Verify the connection

Ask OpenCode to interact with your SendKit account:

OpenCode currently supports stdio and sse transports. The sse transport is used for remote HTTP servers.
