What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

claude mcp add sqlbenchdag -- uvx sqlbenchdag

{
  "mcpServers": {
    "sqlbenchdag": {
      "args": [
        "sqlbenchdag"
      ],
      "command": "uvx"
    }
  }
}

[mcp_servers.sqlbenchdag]
command = "uvx"
args = ["sqlbenchdag"]

{
  "mcpServers": {
    "sqlbenchdag": {
      "args": [
        "sqlbenchdag"
      ],
      "command": "uvx"
    }
  }
}

This one needs environment variables set before it will start: SB_RESULTS_DIR (Directory of experiment result capsules. The package ships the SQL suites, taxonomy and templates but NOT capsules, which are run output — so on a fresh install the catalog tools work and list_results is empty until this points at a results directory.), SB_API_BASE (Optional. Base URL of a running SQL Benchmarks REST API. Leave unset and the read tools mount the API in-process — no server needed. Set it only when the API runs elsewhere, or to use submit_experiment, which needs a process that outlives the request.). The author declared them in the registry entry; get the values from the project itself.
