Verdict

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

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

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 Postgres MCP Pro

Install / run

uvx postgres-mcp --access-mode=restricted

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

{
  "mcpServers": {
    "postgres-mcp-pro": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "DATABASE_URI",
        "crystaldba/postgres-mcp",
        "--access-mode=restricted"
      ],
      "env": {
        "DATABASE_URI": "postgresql://<user>:<password>@<host>:5432/<dbname>"
      }
    }
  }
}

Requires Docker to be installed and running.
