FAQ from Lfwin Payment Mcp
What tools does Lfwin Payment Mcp provide?
It provides four MCP tools: create_payment_order, query_payment_order, refund_payment_order, and query_refund_status.
What environment variables are required?
Both implementations require PAYMENT_API_KEY and PAYMENT_SIGN_KEY. Obtain these from the service provider.

How should I protect my API keys?
Never commit PAYMENT_API_KEY or PAYMENT_SIGN_KEY to version control. Use environment variables, IDE secrets, or a secret management system.
