This tool retrieves financial data from CSMAR databases without modifying or deleting anything. It is a Read operation. Severity is medium rather than low because financial data can be sensitive (potential for competitive advantage, insider knowledge, or privacy concerns if company-specific or non-public), but the tool itself performs no destructive or financial actions.

{
"version": "1",
"default": "deny",
"tools": {
"get_financial_data": {}
}
}get_financial_data is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
