Frequently asked questions
How can I find the most recent data for a specific investment fund?
Use the search_datasets tool with keywords like 'fundos' or 'fi-cad'. Once you identify the dataset, use get_dataset to list all available resources, which typically include the most recent CSV files.
Can I get the direct download link for a data file?
Yes! Use the get_resource tool with a specific Resource ID. The response will include the url field, which is the direct link to the raw data (e.g., a CSV file).
What are thematic groups in the CVM portal?
Thematic groups categorize datasets by market segment. Use list_groups to see categories like 'Fundos de Investimento', 'Companhias', and 'Auditores Independentes' to better navigate the available data.
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 CVM Dados Abertos MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
