Connect Smartlead without code

Smartlead's docs don't confirm Claude or ChatGPT support yet, so we don't list chat-app steps. See the developer setup below, or the Smartlead MCP docs.

From Smartlead's docs: Claude Desktop only, configured in claude_desktop_config.json via npx mcp-remote with the API key in the URL (Node.js required); Smartlead says Claude web is not supported yet.Source: helpcenter.smartlead.ai, checked 2026-10-16

Developer setup (Claude Code, Cursor)

Add this to .mcp.json (Claude Code, project root) or ~/.cursor/mcp.json (Cursor). Remove the // comment line if your client requires strict JSON.

{
  "mcpServers": {
    "smartlead": {
      "url": "https://mcp.smartlead.ai/sse"
    }
  }
}

Add the endpoint to your client config (above), or as a custom connector in Claude.
Add your API key where the config shows the example value. Keep real keys out of shared or committed files.
Test it with a prompt like: “List the tools the Smartlead MCP server exposes.”
