In this hands-on hour you build a multi-agent MCP workflow that does 3 things. You create a MCP server with a catalog of services or tools, connect to a master payment-enabled MCP server, and give your agent a non-custodial identity that can publish to the catalog as well as hold, receive, and spend funds. Any purchasing agent can call a paid tool, watch the payment settle, then hand custody to a second agent — and finish with a verifiable record of every step you can open and inspect.

You leave with:
- a running multi-agent workflow that publishes tools, searches and pays for tools, and transfers custody between agents
- a clear model of how identity and payment attach to an MCP server with no login and no server-side session
- one real failure handled live: an agent that runs out of funds mid-workflow, and how the protocol recovers
- the code and the audit log, yours to fork

Prerequisites: comfort with one MCP client (Claude Desktop, Cursor, or a small Node/Python client), basic command line, an empty GitHub repo, and the workshop repo cloned in advance. No identity- or payment-protocol background needed.
