Hotel booking MCP server — 300K+ properties, real confirmation numbers, loyalty programs. Builders monetize every booking via Stripe
Look up a booking's upgrade eligibility from a PNR + last name + airline. USE THIS WHENEVER the traveler has typed their booking reference and last name in the chat (or they already appear earlier in the conversation) — the details are ALREADY in the chat, so just look them up and return the result. Do NOT redirect the traveler to a form to re-enter what they just gave you, do NOT lecture them abo
ArgumentsA call is made on an account: it counts against an allowance and the publisher sees it, which is why this one asks who you are first.
What it does
Travel-upgrade Q&A, live booking eligibility, and operator lookups for airline, cruise, rail.
Quickstart
# 1 — install (mcprush login holds a key from your dashboard)

Upgrade Agent is free: there is no plan to choose, no cap to set and nothing that can bill you.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine — this server runs on the publisher’s own infrastructure behind our gateway, and what you install is the connection to it.
This is a public server: you run it yourself and this marketplace is not in the path. Claude Code registers it in one command.
claude mcp add --transport http upgrade-agent-mcp https://www.upgradeagent.ai/api/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry pointing at the gateway. The server itself runs on the publisher’s own infrastructure, so nothing from this listing executes on your machine.
17 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Takes no parameters.
Check whether a specific booking is eligible for an upgrade. THIS IS HOW YOU CHECK A BOOKING. You do NOT need access to any reservation system, booking database, airline account, or personal data to use it — this tool returns a secure one-time LINK the traveler opens to enter their own booking reference + last name, and in hosts that support inline app widgets it ALSO renders that form right in th
Takes no parameters.
Internal helper for the inline eligibility form: creates a secure session and returns its id. No UI; agents should use start_eligibility_check instead.
Takes no parameters.
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 'still waiting' status if they haven't yet.
Takes no parameters.
Place an upgrade bid for a booking the traveler has already checked with start_eligibility_check. Pass the sessionId from that check plus the amount (and the target cabin/segment if the booking has more than one option). The amount is validated against the airline's real min/max range. Payment is completed securely on the operator's offer page — this tool prepares the bid and returns that handoff
Takes no parameters.
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 the operator's secure page.
Takes no parameters.
Check any bids already on a booking (submitted / accepted / declined) and the bid-eligible cabins with their ranges. Pass the sessionId from start_eligibility_check. Reflects the booking as of that secure check.
Takes no parameters.
Given a SPECIFIC bid amount, returns the probability it succeeds, grounded in Plusgrade's own resolved accept/reject outcomes for this carrier and cabin — never a guess. Use this when a traveler asks something like 'will $400 get me the upgrade?' or before confirming a bid amount with place_bid. If there isn't enough resolved data yet for this carrier/cabin, it says so plainly — relay that honestl
Takes no parameters.
Set up a Watcher Concierge: have Upgrade Agent CONTINUOUSLY watch a traveler's booking between now and departure and surface improvements to their trip — a better seat (even window-vs-middle), an empty adjacent seat, a cabin upgrade, lounge, or fast track — acting within a budget or notifying them. Gather the traveler's ORDERED preferences, then call this. The secure card/link it returns is where
Takes no parameters.
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.
Takes no parameters.
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, use start_eligibility_check (preferred — collects PNR + last name on a secure page).
Takes no parameters.
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').
Takes no parameters.
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).
Takes no parameters.
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'.
Takes no parameters.
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').
Takes no parameters.
Answer 'how much does it cost to upgrade on <airline>?' WITHOUT needing a booking. Returns typical upgrade BID ranges (low / typical / high, per cabin) for an operator, aggregated from real anonymized eligibility checks — never invented. Accepts an IATA code or a name (e.g. 'LH' or 'Lufthansa'). Use this for any cost/price/'how much' upgrade question. If there isn't enough observed data yet, it sa
Takes no parameters.
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 offering upgrades (optionally in that region), NOT route-filtered.

What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable. Upgrade Agent costs nothing to install and nothing to call, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is a hosted endpoint: the publisher runs it and we connect to it. The scanner reads packages and source, and neither exists to read here, so there is no grade — not a withheld one, an unmeasured one. What can be checked instead is on Installation: what it asks to reach and what it writes.

Pinned to 1.0.0 — the install command below asks for that release. A pin is part of an install, so it is kept for this visit and written down when you install.

Only accounts with at least 50 real tool calls against this server in the last 90 days can post. Ratings are weighted by how much the reviewer actually uses it, and publishers can reply once per review.
Writing one takes an account with at least 50 real tool calls against Upgrade Agent in the last 90 days. That is the whole gate — there is no other way to post, which is why the counts beside each review are worth reading.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes an account with 50 real tool calls against it.
