Frequently asked questions
Can I send SPEI transfers to any Mexican bank from my AI agent?
Yes! Use the create_transfer tool with the recipient's 18-digit CLABE number, the amount in MXN, and an optional concept description. Transfers are processed instantly during banking hours through Mexico's SPEI interbank system.
Can I see which purchases were made with meses sin intereses?
Yes. Use list_credit_card_transactions to see all your credit card charges. Each transaction includes its installment details — whether it was a single payment or spread across 3, 6, 12, or 18 months interest-free (meses sin intereses), along with the remaining installments.
How does the spending analytics feature work?
Use get_spending_analytics with a period (last_month, last_3_months, last_year). It returns your spending broken down by category (food, transport, entertainment, etc.), your top merchants, and comparison percentages against your previous period.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Nubank MX MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
