UCP & MCP - Why isn't anyone taking about this?
It’s been just over a week since the end of NRF 2026 and the announcement of Google’s UCP and I’m staggered by the lack of discussion on the topic given its importance. Why is no one talking about this - maybe it’s just a LinkedIn Algorithm thing and I’m outside of the conversation - or maybe not…?
We’ve been discussing this daily at Daemon in relation to our clients and their challenges on a daily basis.
This is not another incremental standards announcement. Nor is it “just” about agents, AI, or the future of search. What the emerging protocol landscape quietly signals is a fundamental architectural pivot - the shift from Generative AI to Agentic AI. The prize is not attention, but control over the allocation of finite supply.
If you work in media, commerce, marketing, marketplaces, or platforms, you should care deeply. If you work in any industry that relies on search and internet traffic to sell a finite product or service then this post is also for you. This moment looks far less like the rise of the open web… and far more like the early days of programmatic and retail media.
tl:dr - cio/cto briefing: why the universal commerce protocol (ucp) is your next architectural priority
This is not a marketing problem; it's an architectural and operational risk.
Avoid 'Invisibility' Risk: Autonomous agents will soon handle bookings, purchasing, and services for customers. If your inventory isn't exposed via the UCP standard, your entire business becomes invisible, losing transactions to protocol-ready competitors.
Decouple Data from UI: The era of building apps around proprietary APIs is over. UCP and its internal partner, MCP, are the new standards to decouple your core systems from user interfaces, enabling massive scale in automation and preparing your legacy systems for Agentic AI.
Solve the Trust Problem (MCP): UCP's partner, the Model Context Protocol (MCP), solves the biggest enterprise AI hurdle: hallucination. It creates a secure, standard port for agents to safely access real-time operational data (inventory, logs, manifests) with guaranteed accuracy, turning your data into a secure 'Super-Mechanic' tool.
Operational Efficiency: Standardising the Agent-to-Data handshake drastically reduces the complexity, payload size, and latency associated with traditional, monolithic API endpoints, leading to significant long-term cost and performance gains.
Secure Allocation and Governance: This shift is about the allocation of finite supply. You must implement the missing layers (reservation semantics, authoritative inventory state) now. Ignoring these protocols guarantees someone else will define the rules of commerce for the next internet.
The scarcity principle and why you should care
People do not search for the joy of retrieving information. They search because they want to do something - buy a product, book a seat, secure a service. In almost every economically meaningful category, that thing has limited capacity. Retail products sit in warehouses. Airline seats are finite. Energy, labour, tickets - all bounded by real-world limits.
Search engines and marketplaces helped humans navigate this scarcity. Agentic systems change this completely. When agents act on our behalf, there is no browsing, no Search Engine Results Page (SERP). There is intent, constraints, and execution. Scarcity is no longer mediated through pages and rankings; it is resolved through allocation logic.
This is why protocol-based architecture matters. It is an attempt to standardise how that allocation can happen across systems, agents, and suppliers at scale. Whoever sits closest to that layer will own the economics of the next internet.
The two pillars of the agentic web
The Agentic era is defined by two new protocols, decoupling an organisation’s data from its User Interfaces, allowing for massive scale in automation. This is a dual transformation: it addresses the scarcity of commercial inventory externally (UCP) while unlocking the context and capability of internal, operational data (MCP).
- Universal Commerce Protocol (UCP): This is the external standard, acting as the agent’s wallet and voice. Its real function is to act as an inventory consistency and allocation interface for agentic systems. It creates a standardised endpoint for "Booking" and "Negotiation." For a large travel operator, this means passenger agents can automatically negotiate rebooking and vouchers during a cancellation event, resolving disruption without touching a call centre. The risk of ignoring UCP for retail partners is "Invisibility," as customer agents will simply transact with protocol-ready competitors.
- Model Context Protocol (MCP): Think of this as the "USB-C port for AI." It is the internal operational standard that allows an agent to safely and securely see into enterprise data - whether that’s a flight manifest, maintenance logs, or an inventory log - without a custom-built connector for every LLM. It wraps legacy systems, enabling operational agents (like a 'Super-Mechanic') to securely query internal databases and manuals via an MCP server with zero hallucinations.
Beyond the architectural clarity, this protocol-based shift offers significant operational efficiency. By standardising the Agent-to-Data handshake, it drastically reduces the payload size and complexity of communication, lowering latency and data packet costs compared to traditional, monolithic API endpoints.
Why media and commerce companies have an advantage
At first glance, it might seem obvious that this future belongs to platforms or cloud providers. But this view misses a crucial point: media and commerce companies already operate the machinery required to make this work.
Modern organisations, particularly those running sophisticated commerce or media networks, already manage:
- Large-scale inventory systems
- Real-time optimisation and decisioning
- Pricing, prioritisation, and yield management
- Execution at massive, distributed scale
Retail media was about learning how to monetise scarce, valuable inventory using sophisticated allocation logic under demand pressure. That is the same structural problem agentic allocation must solve - just with different inventory. Furthermore, these companies understand that markets fail without governance. Fairness, transparency, and trust are not optional when you are allocating constrained supply; they are existential requirements.
This is why the analogy to retail media is so powerful. Media companies have already navigated the shift from blunt selling to algorithmic allocation. They know how to balance supply interests, demand optimisation, regulatory scrutiny, and commercial outcomes.
The hard realities and missing layers
This opportunity is real - but only if media and commerce companies evolve from impression brokers into neutral inventory exchanges with governance baked in. The shift from media to agentic inventory allocation confronts several hard realities:
Physical Inventory is Stateful: Media inventory is probabilistic and repeatable; physical-world inventory is deterministic, finite, and stateful. A misallocated impression is an inefficiency; a double-booked airline seat is a systemic failure.
Reservation Semantics are Mandatory: Allocation requires atomic holds, confirmations, expiries, and releases. This is closer to financial exchange design than advertising delivery.
Inventory State Must be Authoritative: There must be a single, trusted source of truth for availability, with auditable reconciliation.
Regulation is Unavoidable: The moment allocation impacts essential or constrained services, competition law and fairness obligations follow.
The role of UCP in all of this
UCP should not be viewed as a content or capability protocol. Its real function is to act as an inventory consistency and allocation interface for agentic systems.
In practical terms, that means standardising:
- Availability representation
- Pricing and prioritisation rules
- Reservation and locking behaviour
- Time-based decay and release
- Auditable execution outcomes
Without this, agentic booking collapses under load. With it, agents can operate across multiple suppliers and exchanges without fragmenting the market.
For media companies, UCP is not a threat. It is an invitation to plug existing strengths into a much larger value pool - provided the right layers are added.
The operational shift: agentops and governance
The transition to Agentic AI is an engineering challenge, not just a prompt engineering one. It requires a new approach to running and operating systems that are probabilistic.
New Observability: Traditional tracing tracks requests, but Agentic tracing must track intent. This requires monitoring the "Chain of Thought" of every transaction.
New Governance: The protocols must be managed with robust guardrails, such as starting MCP servers in "Read-Only Mode" and using "LLM-as-a-Judge" frameworks to ensure trust and control.
What needs to happen next
If organisations want to win in this future, four things need to be done deliberately and quickly.
1. Refocus the Frame: Stop framing this as “AI” or “search disruption.” This is about the allocation of scarcity and governance. That is the language that resonates with boards, regulators, and suppliers.
2. Invest in the Missing Layers: These are the price of entry:
- Deterministic inventory state management
- Reservation and locking semantics
- Trust, audit, and reconciliation frameworks
- Explicit governance and fairness models
3. Reposition Commercially: The winning posture is not toll-taking, but neutrality. Success comes from becoming trusted exchanges that maximise total market efficiency, not by extracting rent.
4. Engage with Protocols Early: Standards shape power. Standards like UCP and MCP are an invitation to plug existing strengths into a much larger value pool, but sitting out the conversation guarantees someone else defines the rules.
The bigger picture
Retail media showed us that attention could be algorithmically allocated and monetised. Agentic systems extend that logic to the real world - allocating not impressions, but outcomes.
The companies that thrive will be those that understand this shift early and re-architect themselves accordingly.
Media companies are closer than most realise - especially if they already have plans to evolve.
The window is open. I doubt that it will stay that way for long.
As we prepare for client meetings and real challenges they are facing into within their businesses we love to expand the conversation and maybe even get a few non competing connections together for dinner to discuss it openly and frankly - at Daemon we let our engineers do most of the talking with their experience and their results - so if you’d like to be part of something like that get in touch - I and they would love to talk.
