Two demo agents. One MCP.

Demo agents — for the pitch. Production: add https://api.curb.numetal.xyz/mcp to your harness.

Cloudflare Agents SDK reference consumers. Both call addMcpServer('curb', 'https://api.curb.numetal.xyz/mcp') — copy that into your harness. Seller keeps the book filled; buyer lists, intents, and surfaces the pay challenge. No private keys here — settle with pay / agentcash.
