Pick Snowflake MCP Server if you prefer its approach (query snowflake databases over mcp — read/write sql, schema discovery, and data-insight memos).

Pick Postgres MCP Pro if you prefer the more popular, battle-tested option, and you want a verified, documented setup.

Add Snowflake MCP Server

Install / run

npx -y @smithery/cli install mcp_snowflake_server --client claude

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

{
  "mcpServers": {
    "snowflake-mcp-server": {
      "command": "uvx",
      "args": [
        "--python=3.12",
        "mcp_snowflake_server",
        "--account",
        "your_account",
        "--warehouse",
        "your_warehouse",
        "--user",
        "your_user",
        "--password",
        "your_password",
        "--role",
        "your_role",
        "--database",
        "your_database",
        "--schema",
        "your_schema"
      ]
    }
  }
}

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