Frequently asked questions
Can I create and send invoices?
Yes. Create draft invoices with contact ID and line items, then send them directly to the customer via the API.
How does Moneybird authentication work?
Moneybird requires a Bearer API Key and an Administration ID against moneybird.com/api/v2/{administrationId}/.
Can I list bank transactions?
Yes. Financial mutations (bank transactions) can be listed for reconciliation purposes.
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 Moneybird MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
