Asking an LLM to calculate personal or corporate finances is dangerous. AI models frequently miscalculate decimals, drop expenses from large arrays, or hallucinate total percentages. The Budget Engine MCP solves this by offloading strict financial auditing to a hyper-precise V8 mathematical engine.

The Superpowers

  • Strict 50/30/20 Algorithmic Enforcement: You map the expenses, and the engine mathematically enforces the golden rule of finance (50% Needs, 30% Wants, 20% Savings/Debt), calculating the exact target capital for your given income.
  • Micro-Precision Deviations: Generates exact dollar and fractional percentage deviations. It instantly tells you if your 'Wants' category is $250.45 over budget, preventing LLM math hallucinations and allowing immediate tactical corrections.
  • Deficit & Surplus Diagnostics: Automatically calculates the final monthly surplus or deficit, triggering strict structural alerts ('Deficit' vs 'Healthy') accompanied by algorithmic recommendations.
  • Zero-Dependency Execution: Operates entirely natively within the V8 runtime, guaranteeing extreme speed and deterministic precision without relying on fragile external financial APIs.

You must provide the exact monthly income and a stringified JSON array of categorized expenses. Instantly applies the 50/30/20 financial rule to an income and expenses list, returning strict algorithmic deviations, percentages, and surplus/deficit health checks

Here is my mapped list of expenses and $5000 income. Am I over budget on wants?

Using the analyze_budget tool: Yes, the diagnostic shows your 'Wants' category is $200 over budget (`isOverBudget: true`, `deviation: 200`), consuming 34% of your income instead of the required 30%.

Calculate my monthly surplus and health status.

Using the analyze_budget tool: Your total income is $4000, and expenses are $3200. You have a monthly surplus of $800, and your budget is structurally 'Healthy'.

Based on my $6000 income, exactly how much is my 20% savings target?

Using the analyze_budget tool: The mathematical 50/30/20 algorithm confirms your target for the 'saving' category is exactly $1200.00.

No. The AI agent calling the tool is responsible for tagging each expense as 'need', 'want', or 'saving'. The MCP acts as an infallible mathematical referee, receiving the categorized list and computing the exact metrics and deviations.
