Muxy AI

Muxy AI is an MCP payment gateway deployed on Morph that lets AI agents pay per call when they use external tools. It addresses a settlement gap in the agent economy: MCP specifies how a tool is described and invoked but not how a caller pays for a call, and providers struggle to verify that payment actually arrived.For providers, prices and settlement rules written on-chain split more cleanly into per-call billing than a subscription.

On-chain, the gateway keeps a tool registry holding each MCP service's endpoint, unit of account and price. When a call is made, the PaymentGateway contract escrows the amount, releases it once the result is returned, and refunds it if the call times out. A separate MCP Launchpad lets developers publish services, set billing rules and receive settlement by call volume.
