Lab · Protocol wire

Watch agent protocols talk

Eight agent protocols, one story: a customer charged twice for order 48213. Messages travel between the people, agents, tools and merchants involved, in the shapes their specifications define. Turn on Intercept to hold each message on the wire, read what every field is for, and drop or tamper with it to see how the other side reacts.

A simulation in your browser: no real systems are called. Payloads follow the published specifications; names and values are fictional.

Deep dives, with the real protocol code running in the page: MCP, A2A, AG-UI, A2UI, UCP, AP2 and ANP.
