AI agents call GetV1AvailableSwiftBySwift to retrieve information from BlindPay 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 bank Swift codes, which is a read-only lookup of static reference data. It does not create, modify, delete, or execute operations. While it operates in a financial context, the tool itself does not move money or commit financial obligations—it only provides bank identification information needed for payment operations.
From the tool's definition Tool name 'GetV1Available' and description 'Swift code bank details' indicate a retrieval/lookup operation. The 'Get' prefix and 'Available' qualifier suggest querying reference data (SWIFT codes for banks) without side effects.
