Verdict

Pick DuckDB MCP Server if you want a local (stdio) server that keeps data on your machine, and you want zero-setup with no API key.

Pick Neon MCP Server if you want the official, vendor-maintained server, and you prefer the more popular, battle-tested option.

Add DuckDB MCP Server

Install / run

npx -y @smithery/cli install mcp-server-duckdb --client claude

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "duckdb-mcp-server": {
      "command": "uvx",
      "args": [
        "mcp-server-duckdb",
        "--db-path",
        "~/mcp-server-duckdb/data/data.db"
      ]
    }
  }
}

Requires `uv` (the Python package runner). Install it from https://docs.astral.sh/uv/ if `uvx` is not found.

Add Neon MCP Server

Install / run

npx -y mcp-remote https://mcp.neon.tech/mcp

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "neon-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.neon.tech/mcp"
      ]
    }
  }
}

Claude Desktop connects to remote servers through the `mcp-remote` proxy (installed on first run via npx). Restart Claude Desktop after saving.
