Frequently asked questions
Can I check the status of an IRS form submission via AI?
Yes! Use the get_submission_status tool and provide the Submission ID. Your agent will retrieve the real-time status directly from TaxBandits.
How do I list all my registered businesses?
Run the list_businesses query. The agent will retrieve a complete list of all business entities currently configured in your TaxBandits account.
Is it possible to see draft forms waiting to be filed?
Absolutely. Use the list_tax_forms query. You can pass a JSON filter with the TaxYear and FormType to identify both filed and draft records.
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 TaxBandits MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
