AGNTCon + MCPCon Europe 2026

In one year, agents went from unable to pay for anything to spoiled for choice. x402 (Coinbase, now Linux Foundation) for machine-to-machine. AP2 (Google, donated to the FIDO Alliance) for signed payment mandates. ACP (OpenAI and Stripe) for checkout. MPP (Stripe and Tempo, launched March 2026) for streamed micropayments against a pre-authorized session. Four protocols, four layers, real volume.

What none of them owns is the part that decides whether an agent is allowed to spend this, now, on this. MCP returns HTTP 402 inside a tool call, but it has no concept of a budget, an attribution, or an audit trail. The vendor bolt-ons are already multiplying and fragmenting.

And the question stopped being academic. US regulators now treat agent purchases as ordinary card transactions, Europe is moving to put liability on whoever deployed the agent unless they can produce the mandate and audit trail. The receipts are now a legal requirement with no standard home.

This talk maps the four-protocol stack, shows the MCP payment handshake live, and argues for the one layer the agent economy is still missing.

This is the EUDI Wallet architecture, running inside an agent, 18 months before the Dec-2026 mandate.

Every "agent that verifies you" or "agent that pays" demo skips the hard part: how does an AI agent request a real, government- or bank-grade credential from your device, on any phone, any wallet, Android or iOS, and prove who authorized it?

We'll run the full chain live. An MCP server renders a verifier inside Claude and ChatGPT; the W3C Digital Credentials API requests a credential over OpenID4VP; FIDO caBLE carries it cross-device to your phone; the wallet returns an mdoc or SD-JWT credential held in hardware (StrongBox, TEE, Secure Enclave); an AP2 mandate binds your intent.

Identity is the headline, age, membership, passport, healthcare, with payments as one example. And it's not a stage trick: it's an open-source Digital Credential MCP server, soon to be released and donated, that you can clone, point at your own credential, and ship. Built on open standards, across every platform, with UCP & ACP conformance on the roadmap.

Here are some examples of the demos we're planning to showcase: https://github.com/dzuluaga/mcp-apps-shopping-demo
