Frequently asked questions
Can I access data from multiple accounting platforms like QuickBooks and Xero simultaneously?
Yes! Railz normalizes data across all supported providers. Use the list_businesses and list_connections tools to identify the target entity, then query reports which will return in a consistent format regardless of the underlying source.
How do I retrieve a Balance Sheet for a specific company connection?
First, find the relevant connection_id for the business using list_connections. Then, use the get_balance_sheet tool with that ID to fetch the snapshot of assets and liabilities.
Does this integration allow creating new invoices or only reading them?
The current toolset focuses on read-only operations for auditing and analysis, such as list_invoices, list_bills, and list_accounts. This ensures safe exploration of financial data without accidental modifications.
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 Railz MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
