Add PRIMS – Python Runtime Interpreter MCP Server

Install / run

./scripts/setup_env.sh

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

{
  "mcpServers": {
    "prims-python-runtime-interpreter-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "http://localhost:9000/mcp"
      ]
    }
  }
