Junto Mcp
Gives Claude a universal payment interface that routes through any rail without teaching it provider-specific APIs. You get seven tools: pay, charge, status, refund, balance, providers, and limits. Ships with Woovi/Pix support (live-tested with real Brazilian transactions), plus built-in guardrails for daily spend caps, per-transaction limits, and human-in-the-loop confirmation above thresholds. Every action logs to JSONL for audit. Useful when you want agents to handle real money movement across Stripe, Wise, Mercado Pago, or other providers through a single MCP interface. Named after Franklin's Junto club, the idea being different payment rails at the same table.

Junto
The payment protocol for people and agents.
Send and receive money through any AI assistant. Any payment rail. Built-in guardrails.
Named after Benjamin Franklin's Junto — a society of tradesmen who built civic infrastructure together. Different providers, same table, mutual benefit.
Why
AI assistants are starting to move real money — paying invoices, splitting bills, sending transfers. But every payment provider has a different API, different auth, different settlement times. Nobody should have to teach their assistant how Pix works vs Stripe vs Wise.
Junto fixes that with one MCP server that:
- Exposes a universal payment toolkit to any MCP-compatible client (Claude, Cursor, custom agents)
- Routes to the right provider based on currency, country, and rail
- Enforces spending limits so agents can't go rogue
- Supports human-in-the-loop confirmation for high-value transactions
- Logs every action for audit and accountability
