Get investment bank relationships for a company. Shows which banks have been involved
AI agents call get_banks to retrieve information from Signal8 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 existing information about investment bank relationships—a read-only operation with no side effects. While the Signal8 server deals with financial data, this specific tool does not execute transactions, create obligations, or modify data. It falls squarely into the Read category as it simply fetches and displays historical relationship information.
From the tool's definition Tool name 'get_banks' and description 'Get investment bank relationships for a company. Shows which banks have been involved' indicate retrieval of historical relationship data with no modification or execution capability.
