Connects to airline, cruise line, and rail operator upgrade programs. Muse can check if a booking is eligible for an upgrade, show bid ranges and fixed prices, place or modify bids, estimate bid success, and watch for upgrade opportunities until departure.

Example request: "Can I upgrade my Swiss flight to business class and what would it cost?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Upgrade Agent to help me. It is a free service with an MCP server at https://www.upgradeagent.ai/api/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- check_upgrade_eligibility: Looks up a booking's upgrade eligibility from a booking reference, last name, and airline. Returns eligibility status, upgrade options, bid ranges, and a session id for follow-up bid tools.
- start_eligibility_check: Starts an upgrade eligibility check for a flight, cruise, or rail booking. Returns a secure page (and, where supported, an inline form) for the traveler to enter their booking reference and last name.
- mint_eligibility_session: Internal helper for the inline eligibility form: creates a secure session and returns its id. No UI; agents should use start_eligibility_check instead.
- get_eligibility_result: Read the result of a secure eligibility check started with start_eligibility_check. Pass the sessionId returned by that tool. Returns the live eligibility outcome (eligible options, bid ranges, offer URL) once the passenger has submitted their details on the secure page — or a 's
- place_bid: Places an upgrade bid, or buys a fixed-price (INSTANT) upgrade, for a checked booking. Takes an eligibility-check session id, an amount (omitted for INSTANT), and a cabin/segment. Returns a secure operator link to complete payment.
- modify_bid: Change the amount of a bid already prepared/placed on a booking. Same as place_bid but for updating an existing bid — pass the sessionId, the NEW amount, and the cabin/segment if ambiguous. The new amount is validated against the airline's range; payment/confirmation completes on
- get_bid_status: Check any bids already on a booking (submitted / accepted / declined), the bid-eligible cabins with their ranges, and the current cart. Pass the sessionId from start_eligibility_check. In hosts that render app widgets it shows a manage screen inline. Use modify_bid / cancel_bid t
- get_price_breakdown: Show the itemized all-in cost of an upgrade before the traveler commits — the amount plus any taxes and fees. Pass the sessionId (or conversationId), the amount (omit it for INSTANT — the airline's fixed price is used), and the cabin/segment if the booking has more than one optio
- cancel_bid: Withdraw a bid already placed on a booking the traveler checked with start_eligibility_check. Pass the sessionId (or conversationId). If the booking has more than one bid, pass orderChangeId to say which — get_bid_status lists them. Confirm with the traveler before calling; this 
- predict_bid_success: Estimates how likely a specific bid amount is to be accepted, grounded in Plusgrade's resolved bid outcomes for the carrier and cabin, plus the operator's own bid-strength read when a checked booking's session id is provided. Returns null when there isn't enough data.
- start_watch: Sets up a Watcher that monitors a traveler's booking between now and departure for upgrade opportunities (a better seat, an empty adjacent seat, a cabin upgrade, lounge, or fast track). Returns a secure card/link where the traveler enters their booking, notification preference, a
- get_watch_status: Check a Watcher Concierge watch (created with start_watch). Returns its status, what it's watching for, and any improvements found so far. Pass the token from start_watch.
- ask_upgrade_agent: Answer a general (not booking-specific) travel-upgrade question — how bid/instant/points upgrades work, eligibility rules, bidding strategy, and which airlines, cruise lines, or rail operators offer upgrades. Use this for informational questions only. To check a SPECIFIC booking,
- partner_question_insights: Report what travelers and AI agents are asking about a specific partner's upgrade programs: total volume, the most frequent questions, which agents are asking, and which answers were strong vs. which need review. Pass the partner name (e.g. 'Air Canada', 'MSC Cruises').
- usage_totals: Running totals across the whole system: how many questions have been asked, and how many were answered successfully (quality at or above the success threshold).
- list_partners: List the travel operators that offer upgrade programs, with optional filters. Returns each operator's name, IATA/code, vertical, region, and the upgrade products it offers. Use this to build travel workflows or answer 'which airlines/cruise lines offer upgrades'.
- get_partner_info: Get the full upgrade profile for one operator — products offered (with the official page URL), loyalty program, cabin paths, how to access, and summary. More detailed than ask_upgrade_agent. Accepts an IATA code or a name (e.g. 'AC' or 'Air Canada').
- get_upgrade_pricing: Returns typical upgrade bid ranges (low / typical / high, per cabin) for an operator, aggregated from anonymized eligibility checks. Accepts an IATA code or a name. Says so when there isn't enough observed data.
- search_upgrade_options: Find operators that offer upgrades, filtered by vertical, region, and/or product. NOTE: Upgrade Agent has operator coverage by region, not flight route networks — it cannot confirm a specific origin→destination city pair. If origin/destination are given, results are operators off
