If AI travel agents skip booking fees, does the hotel actually keep that money — or does someone else just grab it?
How does MCP's zero-commission model compare to current OTA commission structures?
This explores whether hotels connecting directly to AI assistants through MCP, the open standard that lets an assistant check availability and book without a middleman taking a cut, actually escapes the commissions online travel agencies (OTAs) like Expedia and Booking charge. It also asks what the corpus says about where those fees go instead.
This explores whether a free, open booking pipe between hotels and AI assistants undercuts the commission model OTAs run on. One caveat first: the collection has no side-by-side commission figures, and nothing in it describes MCP as having a 'zero-commission model.' MCP is a protocol, a shared way for software to talk, and a protocol doesn't charge anyone. So the real question is whether a fee-free pipe stays fee-free once businesses build on top of it. On that, the corpus has a sharp answer: probably not, and the fees may just move somewhere else.
The optimistic case comes from Will hotels need MCP endpoints to reach AI travel assistants?. Ly argues that hotels exposing their rooms through MCP endpoints can be booked directly by Perplexity, Gemini and OpenAI, and that early movers win share 'before new intermediaries emerge.' That phrase gives the game away. Ly's own case assumes the direct window is temporary and that new middlemen will show up. Do protocols reshape markets by enabling multi-vendor competition? adds why this matters: protocols aren't neutral plumbing. They decide whether a market collapses into one dominant platform or opens up to many competing vendors. A shared standard lowers the cost of plugging in. It doesn't guarantee that nobody charges a toll.
The data so far cuts against easy disintermediation. Are AI agents actually removing online travel agencies from bookings? reports that independent hotels' dependence on OTAs rose to 63.4% even as AI agents arrived. Expedia's business-to-business arm grew 24% and now makes up 38% of its revenue. OTAs are plugging into the agents as the back-end that takes the payment and stands behind the booking. Are AI agents actually disintermediating online travel platforms? explains why: AI makes searching cheap, but payment, supply contracts, trust and handling cancellations are still hard. OTAs control those parts. The commission may be shifting from a fee for being found to a fee for completing and guaranteeing the booking.
Here's the part you might not expect to want to know. Commissions also reappear at the agent itself. Can an AI agent serve both merchant and user interests fairly? points out that Meta's Muse earns referral fees from Expedia. The 'free' assistant is funded the same way an OTA is, and that creates the same pull toward whoever pays. And Can cheap agent search actually harm shopping markets? warns that near-free search can make markets worse, not better. Flooding them with similar-looking listings and low-quality sellers can drown out the savings. The comparison isn't 'zero commission vs. 15–25%.' It's whether hotels end up paying a commission they can see, or a hidden one through steering, ranking and referral deals at the assistant layer.
If you want hard numbers on actual OTA commission rates, or a hotel's real cost per booking through MCP versus Booking.com, this collection doesn't have them yet. What it does show is that the fight is over which layer gets to charge: the OTA, the assistant, or a new MCP aggregator.

Ly argues that MCP—a standard enabling AI assistants to query and transact hotel inventory directly—is becoming the booking channel, with early deployers capturing share before new intermediaries emerge. He cites live transactional bookings through Perplexity, Gemini, and OpenAI partnerships, along with industry moves by RateGain and Sabre showing MCP-enabled infrastructure is already moving from concept to production.
O'Reilly argues protocols are market-shaping mechanisms, not neutral infrastructure. He cites MCP's introduction as evidence that a shared protocol can shift an AI chatbot market from platform dominance toward ecosystem plurality where multiple vendors can compete fairly.
Goswami's 2026 travel data shows independent hotels' OTA dependence rose to 63.4% even as AI agents emerged, with OTAs retaining merchant-of-record status through API integrations. Expedia's B2B segment grew 24% year-over-year, now 38% of revenue.
Expedia, Booking, and Airbnb posted strong 2026 gains despite disintermediation warnings. Prieto argues AI may cheapen search but leaves payment, supply, trust, and transaction completion intact—functions OTAs control. This implies value may shift rather than evaporate.
Azhar argues that agents like Meta's Muse, which earn referral fees from merchants like Expedia, face structural conflicts that prevent unbiased recommendations. The incentive to collect fees, not technology, determines which platforms build or block such agents.

A 2026 market design paper argues that imperfect agent search, easy-to-generate similar descriptions, and low-quality seller entry can compound to create worse market equilibria than before agentic shopping became cheap, even though no direct search fees apply.
