Search bank transactions by date range, reference, or amount. Response contains user-controlled fields (Reference, PayeePayer, Notes) that are automatically sanitized.
AI agents call quickfile_bank_search to retrieve information from QuickFile MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries financial transaction data without creating, modifying, deleting, or executing any operations. It is a pure read operation on banking data. While the data domain is financial in nature, the tool itself performs no financial transactions or commitments. The mention of 'user-controlled fields' being sanitized indicates awareness of output handling but confirms read-only behavior.
From the tool's definition Tool description explicitly states it "Search[es] bank transactions" with no modification or deletion capabilities. Parameters limited to search criteria (date range, reference, amount). Response retrieves existing data only.
