Frequently asked questions
Can I manage trust account balances?
Yes. Monitor IOLTA trust account balances, view transactions per client matter, and track deposits and disbursements.
Does LawPay use Basic Auth?
Yes. LawPay uses HTTP Basic Auth with the Secret Key against api.affinipay.com/v1. The Merchant ID is required for identifying the account.
Can I track invoices and outstanding balances?
Yes. List all invoices with amounts, due dates, payment status, and client details. Monitor aging reports and outstanding balances.
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 LawPay MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
