What problem does it solve?
Builders shipping wallet features struggle to keep agents helpful without turning the MCP into a risky custodial money mover.
Who is it for?
Solo developers prototyping non-custodial agent commerce or onboarding flows where the user keeps wallet custody.
Skip if: Teams that need a licensed payment processor, full treasury ops, or zero user involvement in wallet actions.
What do I get? / Deliverables
After registering the npm stdio server, your agent can follow wallet-teaching flows that respect user-held wallets instead of opaque auto-spend behavior.
- Agent-accessible wallet guidance and integration hooks via MCP
- Clearer non-custodial payment UX patterns in your Build prototype
- Foundation to extend wallet flows from the published GitHub repository
