multi_signal_query
AI agents call multi_signal_query 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.
The name 'multi_signal_query' suggests querying multiple data signals, consistent with read-only financial data retrieval given the server's purpose. However, the empty description lowers confidence. No evidence of write, execute, destructive, or financial transaction capabilities. Severity is medium because misuse in a financial context could lead to bad decisions, but likely no direct side effects.
