What It Is

Oops!402 is a hosted remote MCP server (https://oops402.com/mcp) designed for AI assistants like ChatGPT and Claude. After connecting via OAuth, it gives agents a toolset to (1) create/manage a self-custodial wallet using Lit PKPs bound to the user’s OAuth identity, (2) discover x402-protected resources via the Coinbase Facilitator “Bazaar” discovery API, (3) discover x402-capable agents via ERC-8004/Agent0 registries, and (4) execute x402 payments as part of the agent’s plan → run loop.
