Get an institution\
AI agents call get_institution_activity 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 institutional activity data without modifying, executing, or deleting anything. It performs passive querying of financial information similar to SEC filing searches or stock data lookups.
