Verdict

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

Add BigQuery MCP server

Install / run

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

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

{
  "mcpServers": {
    "bigquery-mcp-server": {
      "command": "uvx",
      "args": [
        "mcp-server-bigquery"
      ],
      "env": {
        "BIGQUERY_PROJECT": "{{GCP_PROJECT_ID}}",
        "BIGQUERY_LOCATION": "{{GCP_LOCATION}}"
      }
    }
  }
}

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

Add Supabase MCP Server

Install / run

Add remote URL https://mcp.supabase.com/mcp to your MCP client (OAuth login)

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

{
  "mcpServers": {
    "supabase-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.supabase.com/mcp?read_only=true&project_ref=<your-project-ref>"
      ]
    }
  }
}

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