THE PROBLEM

Two walls.
Every time.

Every AI agent trying to reach a European service hits the same two walls. Not because the demand isn't there — because the infrastructure isn't.

01
Not speakable

No MCP endpoint. No machine-readable interface. The service exists on a website, behind a form, in a PDF. Agents can't interact with it programmatically — so they skip it entirely.

✕ NO MCP · NOT DISCOVERABLE
02
Not payable

No MPP. No programmatic payment layer. Even if an agent finds the service, it can't complete a transaction autonomously. The purchase loop never closes.

✕ NO MPP · NOT TRANSACTABLE
25M
European SMEs structurally invisible to AI agents today

HOW IT WORKS
01
DISCOVERY
Agent discovers

The agent queries the Merx directory via MCP. It finds the service, its capabilities, and its pricing — without human intervention.

02
PAYWALL
HTTP 402 — Payment Required

The service responds with machine-readable payment instructions. Amount, currency, protocol — everything an agent needs to pay autonomously.

03
SETTLEMENT
Merx intermediates

Merx validates the SPT token, routes the fiat transaction through Stripe, and forwards the authenticated request to the EU service.

Transaction settled. Data delivered. Service paid. Every call traceable, compliant, instant.

TRANSACTION SETTLED
THE PROTOCOL STACK

Three layers.
One integration.

Merx is built on open standards. Not a proprietary platform — infrastructure that outlasts any single player.

LAYER 01
⬡
MCP — Model Context Protocol
Speakable

Every service registered on Merx gets an MCP endpoint automatically. Any AI agent that speaks MCP — Claude, GPT, Gemini, custom agents — can discover and query it without custom integration.

97M MCP DOWNLOADS
LAYER 02
⬡
MPP — Machine Payments Protocol
Payable

HTTP 402 becomes the payment handshake. Agents pay autonomously via Stripe SPT — fiat currency, no crypto, no PSAN license required. Legally compliant in France from day one.

STRIPE SPT · FIAT · LIVE
LAYER 03
⬡
Directory — European Registry
Findable

The first European directory of agent-ready services. When an agent needs a French legal service, a German VAT validator, a Spanish logistics API — it checks Merx first.
