Travel Hacking Toolkit

AI-powered travel hacking with points, miles, and award flights. Drop-in skills and MCP servers for OpenCode, Claude Code, and Codex.

Ask your AI to find you a 60,000-mile business class flight to Tokyo. It'll search award availability across 27 mileage programs, compare against cash prices, check your loyalty balances, and tell you the best play.

Quick Start

Install via plugin (no clone)

The easiest way to use the toolkit. Pick your tool:

Claude Code

Inside Claude Code, run:

/plugin marketplace add borski/travel-hacking-toolkit
/plugin install travel-hacker@borski

Done. 42 skills, 6 MCP servers (5 free + LiteAPI which needs a key), and the travel-hacker subagent are installed. Run claude from anywhere and ask it to plan a trip.

To verify the install, run /travel-hacker:getting-started inside Claude Code. It tells you which API keys are configured and points at the local setup script for the missing ones. Or in your shell: claude plugin list | grep travel-hacker should show the plugin.

Codex

In your terminal:

codex plugin marketplace add borski/travel-hacking-toolkit

Then start Codex and the plugin appears in /plugins. Codex pulls the marketplace catalog from the repo (.agents/plugins/marketplace.json) and the plugin manifest from plugins/travel-hacking-toolkit/.codex-plugin/plugin.json, so the install is one command.

Cowork (Claude Desktop's agent panel)

Cowork itself doesn't expose /plugin slash commands, so you can't install plugins from inside a Cowork chat. Install via Claude Code first; Cowork picks it up automatically because both share ~/.claude/plugins/.

1. In your terminal, run claude
2. In Claude Code, run the two install commands from the Claude Code section above
3. Open Cowork inside Claude Desktop. The plugin is already there.

Claude Desktop's chat UI doesn't support the plugin format yet, so use Cowork inside the same app for the full experience.

Configure API keys

The 5 free MCP servers (Skiplagged, Kiwi, Trivago, Ferryhopper, Airbnb) work immediately with zero keys. Cash flight and hotel search work out of the box.

To unlock award search and the rest of the toolkit, you need API keys set as environment variables in your shell. Run the local setup script:

macOS / Linux / WSL / Git Bash:

bash <(curl -fsSL https://raw.githubusercontent.com/borski/travel-hacking-toolkit/main/scripts/setup-keys.sh)

Windows (PowerShell):

iwr https://raw.githubusercontent.com/borski/travel-hacking-toolkit/main/scripts/setup-keys.ps1 -OutFile $env:TEMP\setup-keys.ps1
powershell -NoProfile -ExecutionPolicy Bypass -File $env:TEMP\setup-keys.ps1
Remove-Item $env:TEMP\setup-keys.ps1

The script prompts for each key with masked input, validates them (rejects values with single quotes that would break the export, plus a per-key minimum length sanity check), writes them to the right shell rc with a backup, and never echoes the values back. The exports are single-quoted so other shell metacharacters in the key are safe. Keys never enter your terminal scrollback or any chat session. The /travel-hacker:getting-started skill inside Claude Code points at the same script.
