Frequently asked questions
How do I find my Division ID?
Use the get_me tool to retrieve your current authenticated user profile and the active Division ID associated with your account.
Can I register hours for a specific date?
Yes! The create_time_transaction tool requires a Date parameter in YYYY-MM-DD format to log work entries accurately.
Which regions are supported for Exact Online?
Common regions include 'nl', 'be', 'com', 'co.uk'. Check your login URL (e.g., start.exactonline.nl) to confirm your specific region code.
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 Exact Online Bouw MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
