load_airtime
AI agents use load_airtime to commit financial operations through Africa's Talking Airtime MCP — usually the final step of a payment, billing, or trading workflow. A call moves real money.
Airtime loading involves transferring monetary value to phone numbers, constituting a financial transaction. The server context explicitly describes sending airtime as a core function, and 'load_airtime' strongly implies disbursing airtime (a form of currency/credit). Misuse could result in unauthorized financial transfers. Confidence is slightly reduced due to empty tool description.
From the tool's definition Tool name 'load_airtime' on a server described as enabling airtime transactions via Africa's Talking API, which 'send[s] airtime to phone numbers'
