web_search
AI agents call web_search to retrieve information from Digital Oracle MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Web search operations are read-only queries that retrieve information without side effects. The empty description reduces confidence slightly, but the tool name and context (a financial data server) suggest simple information retrieval. No destructive, financial commitment, code execution, or write operations are implied.
From the tool's definition Tool named 'web_search' with empty description. Based on naming convention alone, web_search typically retrieves data from the internet without modifying or executing code.
