Frequently asked questions
Can the AI automatically validate a shipping address before I calculate the tax?
Yes! Use the resolve_address tool with the full address string. Your agent will return the validated and formatted address, ensuring that the subsequent tax calculation uses the correct jurisdiction data.
How do I void a transaction that was recorded incorrectly?
Simply ask the agent to run the void_transaction tool with the specific transaction code and company code. It will instantly update the status in your AvaTax account.
Is it possible to check my company's tax nexus settings through the AI?
Yes. The list_nexus_by_company tool allows you to audit all active tax jurisdictions where your company is registered, ensuring you are collecting taxes where required.
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 Avalara (AvaTax) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
