FlyBest Travel — Hotel Booking with Advisor Benefits README

FlyBest hotel booking plugin — live hotel tools and Skills for Claude

Search, compare and book hotels with your AI assistant. The FlyBest plugin bundles live hotel tools and the flybest-hotels Skill: check rates for your actual dates and guests, compare rooms, advisor benefits and cancellation terms, create a secure one-time payment page, and manage your own bookings. The Skill guides Claude through quote checks, rate selection and booking verification.

The tools connect to a licensed travel agency's reservation system (Sabre) through MCP. Add the plugin in Claude, then authenticate with your email code when connecting its hotel tools. Compatible clients can also connect to the MCP service directly. Free to use; you pay only the hotel.

Install in Claude: use Customize → Plugins and search for FlyBest, or open the FlyBest plugin page (sign-in required). Follow Claude's prompts to add it and connect the hotel tools. The plugin includes the Skill and remote MCP connection; your email sign-in still authorizes access to your own bookings.

What a rate looks like with the benefits attached

Illustrative example, not a live quote:

Hotel The Mitsui Kyoto, 12–15 Nov 2026, 2 adults

[Partner]   Deluxe Room, King · JPY 898,150 (≈ USD 5,990, estimate) for the stay (tax-in) · free cancellation until 5 Nov
            includes: daily breakfast for two · USD 100 hotel credit · upgrade on arrival (subject
            to availability) · early check-in / late check-out · welcome amenity
[Public]    Deluxe Room, King · JPY 898,150 (≈ USD 5,990, estimate) for the stay (tax-in) · free cancellation until 5 Nov
            includes: —

Same room, same price in this example, and one of them comes with the extras. A programme rate can also cost more or less than the public rate, so the assistant shows both side by side; only the benefits confirmed for the rate you choose apply, and upgrades and early or late times depend on availability on the day. Prices are in the hotel's own currency, with an estimate in yours; you book and pay in the hotel's currency.

What it is

A hotel plugin with live tools and a search-and-booking Skill. Hotels only. You sign in with your email, and your card is entered on a one-time payment page at ai.flybest.org, never in the chat. The MCP service remains available for clients that only need the tools.

Connector URL: https://ai.flybest.org/mcp

MCP Registry

The registered server is org.flybest/travel-hotels. Its publishing metadata is maintained in server.json, including the link to this public repository. This repository provides the hosted service's documentation, MCP Registry metadata, and Claude plugin bundle.

To use the hosted server, add https://ai.flybest.org/mcp as a Streamable HTTP connection in an MCP client with OAuth support, then complete the browser sign-in with your e-mail code. No local server installation or separate API key is required. See Connect for client setup and What you can ask for hotel search, rate comparison, booking and cancellation examples.

Why I built it

I am a travel advisor. The slowest part of the job was asking hotels, one by one, whether a rate includes breakfast, whether there is a credit, whether an upgrade is possible, and until when it can be cancelled. A client says "have a look for me" and I disappear for an hour. So I handed that work to the assistant: it looks, it explains, and when you have chosen, it books.

How it differs from other AI travel tools

Why book through FlyBest instead of direct

The rates come from the hotel's own inventory. Programme rates are often the same price as booking direct, sometimes not, which is why the assistant shows them next to the public rate. Many come through the agency's preferred-partner programmes, which add benefits the hotel does not normally give guests who book direct. Typical inclusions on those rates:

• Daily breakfast for two
• A property credit (commonly US$100 per stay, for dining or spa) where the hotel offers one — the exact credit is confirmed by the agency at booking
• Room upgrade on arrival, subject to availability
• Early check-in and late check-out, subject to availability
• A welcome amenity, and often VIP recognition on file

Rates may include Virtuoso hotel programme benefits where available, through Coastline Travel Advisors, a Virtuoso member agency. Other programmes the agency holds include Rosewood Elite, Mandarin Oriental Fan Club, Peninsula PenClub, Belmond Bellini Club, Dorchester Collection Diamond Club, Maybourne Exclusive, Hyatt Privé, Hilton for Luxury (Waldorf Astoria, Conrad, LXR), IHG Destined (InterContinental, Six Senses, Kimpton), Accor Preferred (Sofitel, Fairmont, Raffles), Shangri-La Luxury Circle, Small Luxury Hotels "Within", Preferred Platinum Partner, Kempinski Club 1897, Langham Couture, Rocco Forte Knights, and Jumeirah. Programme membership changes over time and not every hotel in a brand takes part. When a rate carries these benefits your assistant shows them next to the price, so you can compare a programme rate with the public one side by side, with an estimate of what the breakfast and any stated credit are worth (an estimate, never a discount or a promise); the benefits apply only to the rate you select and are confirmed by the hotel at booking.

The agency also holds Four Seasons Preferred Partner, but those rates are not available through this connection: a partner rate shown at a Four Seasons hotel comes through another programme, with that programme's own benefits. The advisor arranges Four Seasons Preferred Partner bookings directly (jay@flybest.org).

Use your own hotel loyalty membership. Add your member number (Marriott Bonvoy, World of Hyatt, Hilton Honors, IHG One Rewards, ALL Accor …) when booking. Points and elite nights are credited as usual, and your status benefits apply on top of the partner benefits. The assistant can quote public and partner options before you supply a number, then verifies a selected members-only offer with your own number. Brands without a points programme can still offer the benefits stated in their selected partner rate.

Member rates. At Hilton, Hyatt, IHG and I Prefer (Preferred Hotels) properties, the hotel's own member rates appear in the rate list next to the public and partner rates, marked members-only. They book with your own member number: the assistant searches that hotel again with it, and a rate found with your number books only with that number. No member discount is guaranteed, and Marriott member rates are not available through this connection. Joining Hilton Honors, World of Hyatt or IHG One Rewards is free.

Plus: a licensed agency behind every booking (Coastline Travel Advisors), the booking is in your name with the hotel, and you can see and cancel it from the assistant.

Connect

Claude (claude.ai / Claude Desktop)

1. In Claude, open Customize → Plugins and search for FlyBest (direct page, sign-in required: FlyBest plugin).
2. Add the plugin and follow the prompts to connect its hotel tools.
3. Complete the email-code sign-in when prompted. The Skill and MCP connection are included; no separate server installation or manual URL entry is needed.

For a tools-only connection:

1. In Claude's connector settings, choose Add custom connector.
2. Name: FlyBest, URL: https://ai.flybest.org/mcp. Save.
3. Click Connect. On the page that opens choose Sign up with your e-mail, enter your address, type the 6-digit code from the e-mail. Done.

ChatGPT (web, developer mode)

1. Where your account and workspace permit it, open Settings → Apps → Advanced Settings → Developer mode. Workspace administrators may need to enable access first.
2. From Settings → Apps → Create, enter URL https://ai.flybest.org/mcp, authentication: OAuth, and complete the tool scan and connection.
3. Same e-mail sign-in page as above.

ChatGPT support is experimental: custom connectors are a ChatGPT web feature (developer mode), availability depends on your account and workspace settings, and FlyBest has not yet completed end-to-end testing on a real ChatGPT account. The mobile apps are not verified. Read OpenAI's current developer-mode and MCP app instructions for account eligibility, workspace permissions and support for booking/cancellation actions. An administrator may need to refresh and approve updated tool definitions after a connector update.

Other MCP clients

Any client that speaks Streamable HTTP with OAuth 2.1 (dynamic client registration is supported). Point it at the URL above.

What you can ask

• "Find me a hotel in Kyoto for 12–15 November, two adults, near Gion."
• "Show the rates for the Park Hyatt with breakfast, and what the cancellation terms are."
• "The cheapest refundable room, unless breakfast is only a little more." → the assistant recommends by what matters to you (price, benefits or flexibility) and shows a dearer rate of the same programme next to the cheapest when it adds breakfast or a credit.
• "Two adults and two children aged 8 and 10 in Paris, 20–23 December." → city search prices are provisional; the assistant then checks the chosen hotel's rates for all four guests and the children's ages. A rate verified for that family can be booked directly through a secure payment page, including deposit or non-refundable rates after you accept their terms. If occupancy cannot be verified, Jay can help; an adults-first booking is available only if you explicitly choose it, with free cancellation, no deposit or prepayment, and the children still pending hotel confirmation.
• "I'm a World of Hyatt member — show me the member rates at the Park Hyatt Tokyo too."
• "Book the flexible rate under my name — here's my e-mail." → you get a one-time payment link; the booking is made when you submit it.
• "Show my bookings." / "Cancel my Kyoto booking."

Install in Claude Code

This repository is also a Claude plugin bundle: it references the connector and ships the flybest-hotels skill, so Claude gets the house rules (what to check before booking, how deposits and cancellation terms work, what it must never do) automatically.

Use a current Claude Code release. Plugins added to your Claude account can sync to Claude Code when you sign in with the same account; account sync requires Claude Code 2.1.273 or later. See Claude's plugin guide. You can also install this repository directly:

In a terminal:

claude plugin marketplace add flybestorg-cyber/flybest-connector
claude plugin install flybest-hotels@flybest

Or inside a Claude Code session:

/plugin marketplace add flybestorg-cyber/flybest-connector
/plugin install flybest-hotels@flybest

On first use, run /mcp, pick the FlyBest server (plugin:flybest-hotels:flybest), and authenticate. A browser page opens; sign in with an e-mail code.

Validation and updates: claude plugin validate checks the package; it does not install it or complete your hotel-tool authorization. The current Claude manifest omits the old displayName and privacyPolicyUrl keys removed in 1.1.6. The maintainer's root CLAUDE.md is not plugin context; the customer Skill ships under skills/. Existing installations need to update the plugin to receive changed Skill instructions (see Updating).

For older Claude Code versions, or if you only want the tools:

claude mcp add --transport http flybest https://ai.flybest.org/mcp

This connects the server's tools and its own booking rules, without the flybest-hotels skill. Use /mcp, pick flybest, and sign in as above.

The Claude directory entry bundles these tools and the Skill for Claude web and desktop.

Using ChatGPT or another client? The connector sends its core booking rules as server instructions when you connect (this skill is the fuller version), and you can paste skills/flybest-hotels/SKILL.md together with its linked references/quote-integrity.md into a project or custom instructions. Either way, check the payment page and the booking confirmation yourself.

Updating

• Claude web and desktop (installed from the Claude directory): nothing to do. Once a new version is published to the directory, existing installs update automatically.

• Claude Code, installed from this GitHub marketplace: Claude Code does not auto-update a marketplace you added yourself unless you turn it on. Do it once: /plugin → Marketplaces → flybest → Enable auto-update. Or update by hand:

  TerminalCopy

  claude plugin marketplace update flybest
  claude plugin update flybest-hotels@flybest
  

  Then run /reload-plugins in an open session (or restart Claude Code) so the new Skill text is loaded.

• Tools-only connections (claude mcp add, a custom connector, ChatGPT): the tools and their server instructions come from the server, so there is nothing to install. If your client caches tool definitions, refresh or reconnect to pick up changes.

How booking works

1. The assistant asks the connector for a payment page for the room you chose. The confirmation goes to the e-mail you signed up with unless you give another one; you can change it on the page.
2. You open the page, read the price, deposit and cancellation terms written out in full, tick the box, and enter your card. You enter the card only on that page, operated by FlyBest at ai.flybest.org; the details are sent to the hotel reservation system (Sabre) to make the booking. FlyBest keeps the last four digits, the terms you ticked and when you ticked them. Card details are never part of what the assistant sends or receives, so never type them in the chat. The page is open for about ten minutes and the assistant gives you the closing time; if it closes before you pay, nothing is booked or charged, and the assistant can make a new one.
3. The hotel confirms; you get a confirmation number in the chat and the agency gets a copy of the booking. If the same stay's price or terms change before booking, the payment page can show the updated terms and ask you to agree again before continuing. If the price changed before a page could be made, the assistant shows the new price and makes the page once you agree. A different room, date or currency needs a new quote. If the result is unclear, check your trips or e-mail jay@flybest.org with the reference before trying again; do not create another booking while the first is being checked.

To cancel, the assistant first retrieves a cancellation preview, shows the current terms and asks for your confirmation. If the hotel charges a cancellation fee, you must explicitly accept it before the request is sent. Changed terms need fresh confirmation; a completed cancellation does not by itself confirm a refund.

Some rates take a deposit at booking or are non-refundable. The page says so in plain words before you tick; nothing is charged until you do.

Limits

Each public connection allows up to 800 searches, 60 payment links and 60 cancellation requests per day (reset at 00:00 UTC), to keep the reservation system fair for everyone. The assistant tells you when you hit a limit. If a limit stops you from managing a time-sensitive booking, e-mail jay@flybest.org with the booking reference; hotel cancellation deadlines still apply.

Terms, privacy, security

• Terms of use · Privacy notice
• Bookings, cancellations the assistant could not complete, charges, privacy requests: jay@flybest.org with your booking reference (never card details). One advisor, Pacific time; replies usually within one business day.
• Found a security problem? See SECURITY.md.
