query_activities
AI agents call query_activities to retrieve information from Invest Gate Ksa without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The naming pattern 'query_*' and the server's stated purpose—enabling 'conversational querying' of investment datasets—strongly indicate this is a Read operation that retrieves data without side effects. No description limits confidence slightly, but the consistent pattern of sibling tools and lack of mutative language in the tool name support Read classification.
From the tool's definition Tool name 'query_activities' suggests a read operation; description is empty but context shows this server hosts 8 tools for 'conversational querying of structured, source-linked datasets'.
