Verdict

Pick YDB MCP if you prefer its approach (query and explore ydb databases from any mcp-compatible llm using natural language).

Pick MCP Toolbox for Databases (BigQuery) if you want the official, vendor-maintained server, and you prefer the more popular, battle-tested option.

Add YDB MCP

Install / run

pip install ydb-mcp

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

{
  "mcpServers": {
    "ydb-mcp": {
      "command": "uvx",
      "args": [
        "ydb-mcp",
        "--ydb-endpoint",
        "grpc://localhost:2136",
        "--ydb-database",
        "/local"
      ]
    }
  }
}

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

Add MCP Toolbox for Databases (BigQuery)

Install / run

brew install mcp-toolbox && toolbox --prebuilt bigquery --stdio

    "mcp-toolbox-for-databases-bigquery": {
      "command": "/absolute/path/to/toolbox",
