Our reading of Flop, from the data

Flop is a code execution & sandboxes MCP server from ninjatrader542, listed in the official MCP Registry.

We haven't measured its tool list yet, so its token cost is unknown.

It runs as a hosted endpoint, so there is nothing to install.

Install Flop MCP server

claude mcp add --transport http flop https://opti.tailbdecdd.ts.net/mcp

{
  "mcpServers": {
    "flop": {
      "url": "https://opti.tailbdecdd.ts.net/mcp"
    }
  }
}

{
  "mcpServers": {
    "flop": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://opti.tailbdecdd.ts.net/mcp"
      ]
    }
  }
}

Or add it as a custom connector under Settings → Connectors. The config above bridges via mcp-remote.
