daily_average
AI agents call daily_average to retrieve information from ExpenseTracker MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on the tool name, 'daily_average' likely computes and returns a daily average of expenses, which is a read/query operation with no side effects. The sibling tools context (expense tracker with summarize, monthly_report, top_spending_categories) supports this interpretation. However, the empty description lowers confidence. Severity is low as misuse of a read-only analytics tool has minimal blast radius.
From the tool's definition Tool name 'daily_average' suggests a read/analytical operation; description is empty and uninformative.
