Building an AI Agent That Knows When Not to Guess (Qwen + MCP)

A payment landed for exactly half an invoice's value. The payer's email matched the customer on file. The reference generated by Paystack — the Stripe-equivalent payment processor across Africa didn't match anything at all.

Qwen looked at it and came back with 30% confidence and no invoice named.
