Verdict

Pick Label Studio MCP Server if you prefer its approach (manage label studio projects, tasks, and model predictions from your mcp client via the label-studio-sdk).

Pick Memory (Knowledge Graph) if you want the official, vendor-maintained server, and you prefer the more popular, battle-tested option.

Add Label Studio MCP Server

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

{
  "mcpServers": {
    "label-studio-mcp-server": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/HumanSignal/label-studio-mcp-server",
        "mcp-label-studio"
      ],
      "env": {
        "LABEL_STUDIO_API_KEY": "your_actual_api_key_here",
        "LABEL_STUDIO_URL": "http://localhost:8080"
      }
    }
  }
}

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

Add Memory (Knowledge Graph)

Install / run

npx -y @modelcontextprotocol/server-memory

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

{
  "mcpServers": {
    "memory-knowledge-graph": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-memory"
      ],
      "env": {
        "MEMORY_FILE_PATH": "/absolute/path/to/memory.jsonl"
      }
    }
  }
}
