How many months to reach a goal.
AI agents call savings_goal to retrieve information from Finance MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a financial calculation (projecting savings timelines) but does not move money, create financial obligations, modify accounts, or execute transactions. It is purely computational and informational, analogous to a query or forecast. Therefore it falls under Read rather than Financial, which is reserved for tools that actually commit financial obligations or move funds.
From the tool's definition Tool name 'savings_goal' and description 'How many months to reach a goal' indicate a calculation/projection function that retrieves or computes financial information without modifying any data or executing transactions.
