Cline (VS Code Extension)

  1. Open Cline in VS Code (Sidebar -> Cline icon).

  2. Click "Configure MCP Servers" in the Cline panel. This opens cline_mcp_settings.json.

  3. Edit cline_mcp_settings.json, adding the following within the mcpServers section and replacing <YOUR_NEON_API_KEY> with your Neon API Key:

    "neon": {
  "command": "npx",
  "args": ["-y", "@neondatabase/mcp-server-neon", "start", "<YOUR_NEON_API_KEY>"]
}

  4. Save cline_mcp_settings.json.
