Filter entries by date range
AI agents call filter_by_date to retrieve information from ContextForge MCP Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data by applying a date-range filter—a purely read operation with no side effects, no data creation, modification, or deletion. It returns a filtered view of existing entries. The low severity reflects minimal risk: even if misused by an AI agent, filtering operations cannot corrupt or compromise data.
From the tool's definition Tool name 'filter_by_date' and description 'Filter entries by date range' indicate a query/filtering operation with no modification or deletion of data.
