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.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
