01 · Install BigQuery MCP

Claude Code

claude mcp add snowleopard-ai-bigquery-mcp -- uvx sl-bigquery-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "snowleopard-ai-bigquery-mcp": {
      "command": "uvx",
      "args": [
        "sl-bigquery-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
