01 · Install Fly Io

before you install - you'll need

Set FLY_IO_API_TOKEN, FLY_IO_APP_NAME before connecting.

Claude Code

claude mcp add pulsemcp-mcp-servers-experimental-fly-io -- npx -y fly-io-mcp-server

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "pulsemcp-mcp-servers-experimental-fly-io": {
      "command": "npx",
      "args": [
        "-y",
        "fly-io-mcp-server"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
